A guide to gluing Zinc Stopends

The Infinity Zinc rainwater system is available next day in 115mm and 125mm deep half round profile and in 80mm round downpipes. Other sizes are available with a longer leadtime and with prices available on request.
Over time, Zinc forms a thin layer called a ‘patina’. This patina covers the material and protects it from weather elements, such as heat, wind and water. It is utterly immune to the harmful effects of UV rays. This hard-wearing property means Zinc will last up to 50 years even in the most testing environments. The ‘Quartz’ Zinc system Rainclear stock already has the appearance of ‘pre-weathered’ Zinc.

Lightweight and easy to install

  • The gutter lengths can either be glued together or use our EPMD lined Union-connectors. There is no welding, soldering.
  • Wrap-around gutter outlets offer downpipe positioning flexibility.
  • Swaged-necked downpipes and fittings simply slot together.
  • The Zinc system comes with downpipe brackets that require galvanised M10 screws to secure them in place. The M10 screws need to be ordered separately from the brackets, at either 100mm, 140mm or 200mm lengths system.
  • The Zinc stop ends need to be glued in with the high-tech adhesive (applicable on damp surfaces, UV-resistant, solvent-free, extremely high bond strength,) we supply. This is still a simple and proven method.

A short video demonstration always makes an explanation much clearer and easier to understand, so we put one together for you below.

Video transcript:

  • Apply the glue evenly round the ‘lip’ of the outer edge of the stopend
  • Offer the stopend up to the gutter and, from ‘ear’ to ‘ear’, insert the gutter into the glue in the stopend lip
  • Make sure the gutter end is pressed tight up against the inside of the stopend
  • Clean off any glue that has been pressed through to the outside
  • To line the inside of the stopend with a thicker line of glue, cut the glue’s tip a ½” further down
  • Line the inside of the stopend with the glue
  • Use your ungloved and dampened finger to smooth the glue along the inside edge
  • Allow the glue to dry fully (6-8hours) before testing the strength of the bond!

Dusty Grey Infinity Galvanised Steel Fascia and Soffit to match windows and doors case study image

Consider an Infinity Galvanised Steel Fascia & Soffit facelift – because your home is worth it, isn’t it?

Unique to the UK market, Infinity Galvanised Steel Fascia & Soffit.

Why Infinity Galvanised Steel? 

Because it is light and, therefore, easy to handle and install.  Because it is long lasting - not fading or creaking in sun and heat, not rotting in the wet - but adding a touch of class & style instead.  Because it is available with next day delivery in 3 profiles and 3 robust colour coatings, and can also be ordered in almost unlimited colours if you are happy to accept a surcharge and a longer lead-time. Because a value adding facelift that also protects your home from the elements – well, that has to be worth considering, doesn’t it?

What is it likely to cost?

For a typical 3-bedroom semi-detached house on two floors, replacing soffits and fascia will require the erection of scaffolding - The cost of fascia and soffit is a small component of the overall price, with scaffolding often costing around a third of the total.

For example,

  • Scaffolding – £1,000
  • Material
    • uPVC gloss white– £230 (N.B. ‘Rosewood effect’ is almost 3 x as expensive)
    • Infinity Galvanised Steel in White Grey – £609.97
  • Replacement timber/tiles and waste – £50
  • Labour – £1,200

The ‘biggie’s often quote for full scaffolding while local tradesmen often use towers or work platforms, or have a mounted lift on their van instead; to help bring the % cost of scaffolding down; but also, if you have a conservatory or others’ parked cars /caravan in the way, scaffolding won’t actually be the best option. Sometimes, if the job runs over, the cost of scaffolding can spiral while you wait for a new slot when the team that put it up can return to take it down.

It is unfair to expect a quote for a job without an inspection being undertaken as old soffit and fascia can hide a multitude of sins. Damaged rafters and fascia boards may need to be replaced with new timber (Infinity Galvanised Steel Fascia & Soffit are designed to clad a timber frame) but equally, you shouldn’t have to pay for the inspection for a quote, or be time-pressured into accepting one quote before you’ve had a chance to get comparisons.

Our research into online reviews found complaints that “the 'biggies' always overcharge” initially. And one reviewer said, “They tend to use great sales staff but so often this isn't followed up by good fitters!”. Our trade customers are often small local tradespeople and we are big believers in keeping locals in business. All fitters should be registered installers so make sure your fitter is.

Why are the soffits not vented?

Reviewers also said, “a vented soffit will get filthy very quickly if you live by a road and is difficult, if not impossible to clean” so Rainclear created a solid soffit design.

What makes a Steel Fascia & Soffit facelift a good investment?

Replacement of your Fascia and Soffits adds value to your property and Infinity Galvanised Steel Fascia & Soffit are designed to be a long-lasting solution. They will not require repainting or additional wood treatments and, unless you fancy a change of colour later, they will not crack or fade and, therefore, will not need replacing. The manufacturers of Infinity Galvanised Steel Fascia & Soffit offer a 15-year product warranty, but the well-established matching rainwater system we also stock has proven to last over 25 years. Installers may offer their own guarantees as well, so that you can be reassured that they will return to resolve any installation issues.

Tips for fitting Stopends, Fascia Brackets & Gutter Unions

At Infinity Galvanised Steel we do not install guttering - we just sell it. But we do make up hundreds of steel gutter samples for our sample boxes, and that means attaching a stopend, a short-back fascia bracket and a gutter union with security tab to (an admittedly short length of) a gutter!

The sales team here have taken phone calls asking how the stopend or fascia brackets go on (admittedly sometimes before they’ve even unpacked them!) and seen case study images of the installed gutters where the security tab has been overlooked.

So, while not claiming to be any kind of experts, we wanted to share with you what we have  found makes fitting easier. 
(and what, if you didn't know, might cause you unnecessary difficulties)

It is nearly impossible to describe these things over the phone when you can't see the components and describe their features, so we’ve made 3 very short videos that we hope do the job considerably better than we ever could!

Tip 1: Fitting the stop end

Tip 2: Fitting fascia bracket

Tip 3: Fitting gutter union - highlighting the security tab

Zinc Rainwater Range Introduced to the Infinity Family

Zinc is proving to be a popular building material and in response, Infinty have added the quartz zinc rainwater system to its stock for next day delivery.

Over time, Zinc forms a thin layer called a ‘patina’. This patina covers the material and protects it from weather elements, such as sun, wind and water but the change is practically invisible. It is immune to the harmful effects of UV rays.

The main advantages to the customer of a Zinc rainwater system are:

  • Sustainability - it is a green /eco product
    • there is no shortage of zinc as a resource and in addition
    • it can be 100% recycled at end of life.
    • Many customers today want to lower their carbon footprint and reduce their impact on the planet.
  • Aesthetics - Choosing Zinc as a rainwater solution is stylish statement for those after a different, unique finish that will maintain a striking appearance.
    • The ‘quartz’ zinc we have chosen to stock has the colour and texture of pre-weathered zinc.
    • It has been used as a roofing product historically and also contemporarily - it gives a similar appearance to lead but does not have a toxic run off and will not stain adjacent materials - great for water harvesting systems helping to keep the water clean and pure.
  • Durability - with a lifespan of nearly 100 years - it is completely unaffected by water, temperature changes and UV rays.
  • Non-corrodible - A fundamental advantage Zinc has over other materials is that it’s a highly corrosion resistant material, which is ideal if you live in an exposed location or by the coast. Its hard-wearing properties mean Zinc will last up to 50 years even in this most testing environment.
  • Low maintenance - requiring no decoration or cleaning, just the removal of debris that may fall into the guttering, making it suitable for commercial, civic and residential buildings.
  • Lightweight and easy to install
    • the stop-ends simply glue in.
    • The gutter lengths can be glued together or use our EPMD lined Union-connectors so there is no welding, soldering or messy silicone involved.
    • Wrap-around gutter outlets offer downpipe positioning flexibility.
    • Swaged-necked downpipes and fittings simply slot together.
  • Value - Over the life cycle of a building Zinc generally is one of the most competitive building material available. - PVC gutters and downpipes are chosen over zinc and copper mainly due to the initial outlay, however, when you look at the ‘whole-life costs’, that is the cost spread out over the systems’ and buildings’ expected life, zinc and copper actually perform well on cost.


For generations, European architects have specified zinc as a building material for all types of buildings because it would last and endure harsh weather conditions. And it is predicted that more and more homes will feature Zinc in the future because it is an attractive, durable, and green building material.

As more homeowners choose quality and sustainability over initial cost in home renovations, they’re choosing zinc over other materials.

It’s a popular choice for those who are using zinc elsewhere in the build or simply prefer grey-to-charcoal shades to match the rest of the house.

Anthracite Grey Steel Case Study in AberAC

Are you concerned about Galvanised Steel rusting?

Some old steel rainwater systems have given all a bad reputation. Some steel components without a Galvanised core and zinc/magnesium protection layer sold to property owners in coastal areas in the past resulted in problems later.

What protects Infinity Galvanised Steel?

Infinity Galvanised Steel benefits from a unique 4layer system which protects the steel and enhances the longevity of the colour.

  1.  The galvanised Steel Core
  2.  The Zinc/Magnesium corrosion protection layer
  3.  A primer bonding coat adds further corrosion protects
  4.  Finally, the polyester top coat with maximum UV and scratch resistant properties*

*The science bit: Scratch resistant to >_30 N and UV resistant RUV 4

4 protective layers that make Galvanised Steel long-lasting even in coastal areas


Another key factor in ensuring longevity is the installation process – and CUTTING in particular. NEVER use mechanical grinders or hole saws – They will damage the material. ALWAYS cut using metal snips/shears – THIS method of cutting seals the ends of the metal edge and prevents the ingress of rust.

Why Choose Infinity Galvanised Steel?

  • Infinity Galvanised Steel is available in 6 colours in 24 hours or a considerably wider range of colours than uPVC if you are prepared for a longer lead time and the possibility of additional surcharges (depending on the size of the order)
  • Comes with 20% deeper flow-capacity meaning it WILL cope and continue to work effectively to protect your home even with the new extremes of the British weather
  • Is more stylish and more robust than uPVC or rival steel guttering systems and retains its good looks for longer
  • does not crack, creak or fade
  • 100% recyclable at the end of its life

Although it may be a slightly more of an expensive, its beauty, durability and recycle-ability – reducing environmental impact – makes it the more cost-effective choice as the long-term advantages far outweigh the initial outlay.

Anthracite Grey Steel Case Study in AberAC


“I spoke to my Mum’s cousin recently, whose son was building a house on the East Coast of Scotland. He thought his only options were plastic or Aluminium – a huge leap up in price – as he has seen old steel rainwater systems bubble.  I tried to explain that our colour coated Galvanised steel wouldn’t do that, would only cost slightly more than PVCu but last considerably longer, and in the Anthracite Grey, would match the aluminium window frames he’d selected for the project. I just couldn’t get him to consider taking another look at steel. After his previous experiences, his mind was made up.” Fiona Nevada, Marketing Coordinator at Rainclear.


Copper & Zinc from Infinity!

If we can’t convince you to take another look at Galvanised Steel for your coastal property’s rainwater system, how about a quote for Copper or Zinc? These are both naturally beautiful materials, extremely long lasting and we hope that we can surprise you with the value for money they offer. If, like my relative, you are building a dream home you intend living in and maintaining for yourself into your old age, you really ought to consider the long-term costs in both money and time and the benefits of a system you will not need to repaint or replace in your lifetime and that actually looks better and better as it gets older. If only we could say the same of ourselves!

Give your home a unique finish that needs virtually no maintenance.

Infinity Copper case study Image

Did you assume a Copper Rainwater System would mean soldering? Not this one!

What no soldering copper guttering?


AND NO special skills are required either to install this copper guttering.

The clever, innovative design of this system means installation is made easy:

  • Stop-ends with EPMD rumbber seals just are 'push-fit'
  • The Gutter Unions come with an EPMD rubber seal, snap-close jaws and a security tab you 'thumb' down to lock the jaws closed
  • The Wraparound outlets, where the gutter meets the downpipe, 'wrap-around' the gutter so can be placed wherever you need them along the run of gutter
  • Or you can choose a pre-fabricated outlet, which uses the gutter unions to join onto the run of gutter
  • Downpipes and bends have swaged necks, which simply 'slot' together

So NO soldering, brazing, messy silicone or rivets required anywhere in the system.

Some competitors only offer 'copper coloured' systems - but there's greater benefits to using Copper for your rainwater system than just great looks!

Infinity Copper case study Image

The initially shiny finish will weather from a high sheen through a deeper reddish-brown, which gives it a ‘rustic’ look, to verdigris green. The characteristic of copper to patinate to a beautiful Verdigris actually creates a protective layer over the metal beneath, reducing the speed of corrosion through the metal so that copper can last 50-100 years even in proximity to the sea.

The colours of Copper as it ages

Metals Galvanic Scale - Galvanic Corrosion is an electrochemical process which occurs when dissimilar metals are in contact with each other in the presence of an electrolyte - rain water and salt water make especially good electrolytes. Using metals close together on the scale reduces the prevalence of bimetallic corrosion.

Galvanic Corrosion is an electrochemical process which occurs when dissimilar metals are in contact with each other in the presence of an electrolyte - rain water and salt water make especially good electrolytes. Using metals close together on the scale reduces the prevalence of bimetallic corrosion.

For example: Aluminium rainwater systems should not be used with copper roofing. When rainwater from the roof makes contact with the uninsulated aluminium the risk for galvanic corrosion to occur is high because of the copper ions in the water. The closer the galvanic potentials are, the less corrosion that will occur.

Some metal rainwater systems are also at risk in contact with some no-metallic materials such as cedar or birch cladding - many woods contain volatile alcohols, and oils that have a solvent action on some protective coatings applied to metal -  Iron and uncoated steel are more susceptible to these than aluminium or copper.

Why Choose Copper?

Eco choice
Copper is sustainable, it is 100% recyclable with most mined copper still in use today, reducing its environmental impact.

Aesthetic choice - distinctive appearance
Left to age naturally copper guttering will start to mellow within weeks, changing through various shades of brown and bronze until eventually forming a green / blue patina unique to copper. The time taken for the patina process to start depends on the location of your property, local weather conditions, distance from the sea and other forms of acidic pollution. If you don't want to wait for the patina finish to develop naturally, a solution can be applied after installation that will age your copper gutter within a few hours. Eventually copper will always go green and we recommend that you do not coat the copper to try and keep it bright. Instead it will continue to look good for years to come enhancing and protecting your property.

Great for Rainwater Collection
Water conservation is becoming increasingly popular. Copper acts as an algaecide and fungicide, keeping growths such as moss and lichen to a minimum, therefore keeping gutters clear and excellent for rainwater harvesting. Copper also mildly disinfects the water, which is great for putting on plants as it has a balanced pH and is free from chemicals such as chlorine. Plants actually grow better using the pH balanced and chemical free rainwater collected with copper. You get more suds when washing the car and it makes car and window washing smear-free (the streaks and dots are limescale).

100% natural
Being 100% natural and non-toxic, copper guttering is particularly suited for use in conjunction with a copper roof as a means of rainwater harvesting. Copper is a wholly natural material present in and essential to all plants, animals and humans. Unlike other materials such as lead, copper is non-toxic and does not accumulate in the body. The natural beauty of copper will instantly enhance the aesthetic value of any building complimenting the current trend for the use of natural building materials such as Oak, Stone, Slate, etc.

Maintenance free
Copper is one of the most noble metals (see Galvanic Scale illustration). Its durability and resistance to corrosion makes copper guttering particularly suited for use in virtually any atmospheric conditions and in areas that are difficult to access after completion. It is a wonderfully low-maintenance option for guttering systems as it will not require painting or cleaning (if you are happy to allow it to patina with age) other than the removal of debris that may fall into the guttering - ideal where some parts may be difficult or dangerous to reach. A good choice for commercial and Local Government properties where the Health and Safety of facilities maintenance staff needs to be considered.

Exceptionally long product life span
Copper protects itself by forming a patina that ensures an exceptionally long product life span of 100+ years and as guttering prevents damage to brickwork and roofs by diverting rainfall from the property once installed.
It is this patina that gives copper its distinctive look as it ages. When supplied new it has a bright and shiny finish, but in a matter of months this transforms to an intensely rich, earthy shade. Over the coming years, depending on the atmospheric and geographical conditions, your copper rainwater system will develop the distinct green patina associated with copper.

It may seem a more expensive choice initially, but its beauty, durability and recycle-ability – reducing environmental impact – makes it the more cost-effective choice as the long-term advantages far outweigh the initial outlay.

Give your home a unique finish that needs virtually no maintenance and will last for generations to come – the long-term value cannot be understated.

Plain Box Hopper in all 6 colours and copper

New Plain ‘Box’ Hopper added – based on customer feedback

We love to offer exceptional service levels as well as the highest quality products and value for money to our customers.

Bespoke Colours – Pale Green & Pale Stone, for example

It is possible to order bespoke colours for your Galvanised Steel colour coated gutters, downpipes, hoppers and fittings, but it will add to the cost and to the delivery time.

Here we take a look at 2 colours, as an example, that you may wish to consider, each for different reasons:

  1. Pale Green RAL6021 to match a popular colour for windows, doors and conservatories, sometimes referred to as ‘Chartwell Green’

RAL 6021 Pale Green Block  Chartwell Green

  1. Pale Stone RAL1015 to match Cotswold stone or similarly stone clad or stone constructed buildings where you’d like the downpipes to blend in with the stone façade. RAL1015 is also sometimes referred to as  as 'Ivory White'.

Note that it’s the RAL colour number that remains consistent across different manufacturers and different products.

RAL1015 Pale Stone Block Ivory White

What effect does choosing one of these bespoke colours have on the price?

As you can see from the table below, for these two colours it would cost an additional 57% on top of the price for the stocked colours: Black, Brown, Anthracite Grey, Dusty Grey and White.

These calculations have been based on the components required for a large 4 bedroomed self-build.

Bespoke colour Chartwell GreenRAL 6021 Price Comparison Table

It just so happens that the RAL1015 - Pale Stone is the same cost as the RAL 6021 - Pale Green. They are both in the manufacturer’s price category band 2.

What effect does choosing these bespoke colours have on the delivery time?

The manufacturers require about a week to paint your system components the bespoke colour, after possibly having to ordering the powder in specifically, and we have regular weekly deliveries -  so you should allow a total of between 2-3 weeks for delivery of your bespoke colour system.


So, what bespoke colour do you have in mind now?

  Not every colour will be available in the powder and some colours may fall into a price category ‘band’ that costs more.

  We will need you to select the RAL or BS colour that most closely matches any colour you are considering matching to.

  We will need to know all the system components you require in order to get an accurate quotation, but remember that we can do a take-off from architect's drawings for you

Just give us a call on 0800 644 44 28 to discuss colour with our knowledgeable, friendly sales team.


Swan Neck 2 Bend Offset

Swan-Neck Offsets: 60mm, 60-210mm & >210mm

70 Degree Bend with measurements

Two 72 degree bends make a ‘swan neck’ to offset the downpipe from the roofline to the wall of the building.
●   In the 80mm diameter downpipe 2 bends make a maximum of 210mm offset
●  In the 100mm diameter downpipe 2 bends make a maximum of 255mm offset

Anthracite offset illustated letterbox image

●  There is a 60mm fixed offset available in both sizes of downpipe


●  For any other offset between 60mm and the maximums you should pivot the ‘swan neck’ inside the downpipe to whatever distance from the wall is required to meet the outlet at the roofline. So that the running outlet or prefabricated outlet is not directly above the downpipe but set off to the side as necessary.

Offset Bends measurements table

Swan Neck 2 Bend Offset

●  For even larger offsets, as in the case study in Aberystwyth, a cut section of downpipe can be inserted between the two bends, cut to what ever additional length is required

(N.B. remember to allow for the overlap of the swaged necks of the downpipe piece and of the the bends in your calculations).

How to select the rigth size gutters with a flow calculation

Choosing the right size of Gutters and Downpipes

As extraordinary weather patterns become ever more regular with intense rain storms causing major challenges for rainwater disposal it has become ever more important to ensure you have the calculating right flow requirements or ‘flow capacity’ required by your property to select the right size of gutter and downpipe to adequately protect your property from rainwater.

The rainwater system, comprising gutters or hoppers and downpipes, is essential because it offers protection to your property from ingress by water to the roof, walls or foundations which can cause serious damage to the integrity of the property if it is not efficiently and effectively directing rainwater away from the building and safely into the subsurface drainage system below the building.

This guide describes what goes into a flow calculation:

Step 1: Identify the Geographical Location and Rainfall Intensity

British Standard BS EN 12056-3: 2000 contains maps showing rainfall intensity in litres/second per m2

for 1, 5, 50 and 500 year storms of 2 minute duration.

(All external gutters designed for 1 year event).

Step 2: Calculate the 'Catchment Area' of the roof

CA = (P+H/2) x L

CA = Catchment area in square metres
P = Horizontal distance between eaves and ridge
H = Height of roof
L = Length of eaves

Step 3: Frequency and Positioning of outlets/downpipes

Calculate the number of outlets per run.

The roof area, the pitch of the roof and the number of ‘drops’ (downpipes coming down from outlets in the guttering around the building) determine the 'flow'.

– we need these details from you to calculate the flow capacity for you.

Step 4: Calculate Flow Requirements

Overall rainfall: Catchment area (CA) x Rainfall intensity (RI) = Overall Rainfall (OR)

Flow rate per outlet: Overall rainfall (OR) ÷ Number of outlets = Flow rate per outlet
Choose gutter/outlets according to published flow rate capacities.

How to select the rigth size gutters with a flow calculation

Depending on building type, a safety factor should be allowed for the sizing of internal gutters.

We can do the flow calculation for you.

Don’t worry, you are not expected to work this out by yourself! The British Standard Geographical Location and Rainfall Intensity Maps needed in calculations are specialist maps and so are obviously expensive to buy and keep updated.

We offer a free ‘Flow Calculation’ service. Just give us a call on 0800 644 44 28 and let us have the details above to do the calculation for you.
