Advantages of Box Profile Sheets
From their ability to withstand impact to the ease of installation, box section roofing sheets offer a wealth of benefits. This makes them ideal for tradespeople and homeowners, whatever your requirements.
With galvanised steel at the core of our box profile roofing sheets, they offer superb strength along with protection from corrosion. When buying these roof sheets, you can choose between a polyester or plastisol coating. These specialised coatings offer further resistance to chemicals, the weather and UV light.
Box profile sheets are suitable for roofs with pitches as low as 5° and can also be installed vertically to clad the exterior of a building. This makes them a fantastic all-in-one solution for storage facilities or agricultural buildings, allowing you to achieve a consistent aesthetic throughout.
Costing between £7 and £10 per square meter, box profile roofing sheets are incredibly cost-effective when compared to most alternatives. They also offer a lifespan of up to 25 years whilst requiring virtually no maintenance, providing you with a long-term roofing and cladding solution.
Box profile sheets simply overlap to make installation hassle-free. Purposely designed accessories also help you achieve a professional finish whilst ensuring your sheets are secure. This includes specially designed fixings to suit both timber and steel structures, both available in various lengths.
Types of Box Profile Roofing Sheets
These roof sheets are available in a variety of materials and profiles. Our steel box profile sheets can also be coated with either polyester or plastisol, which help to extend their lifespan by up to 10 years.
Steel Box Profile Sheets
Available in either 0.5mm or 0.7mm thicknesses, our steel box profile roofing sheets are ideal for both roofing and cladding applications. These are available in a range of lengths and profiles, including the 32/1000 profile sheet. You also have a choice of polyester and plastisol coatings should you wish to increase the durability of your roof sheets.
Anti-Condensation Box Profile Sheets
An integrated anti-condensation membrane prevents moisture from building up and dripping onto the items beneath. These are available in the same range of profiles and lengths. They can also be coated with polyester or plastisol to extend the lifespan by up to 10 years.
GRP Box Profile Sheets
Available in a 32/1000 and 34/1000 profile, our GRP box profile sheets allow you to introduce a rooflight into the roof of your warehouse, stable or garage. At 1.5mm thick they provide adequate protection from falling debris and a choice of lengths minimise the need to cut them yourself.
Uses of Box Profile Sheets
These roof sheets can be used to reroof buildings as well as introduce exterior cladding. The choice of profiles, coatings, and colours available also suit a variety of environments. This includes busy industrial estates and rural farms.
Commercial warehouses, residential garages, and other storage areas can be adequately protected with box profile roofing sheets. Plus, with a lifespan between 10 – 25 years you needn’t worry about the disruption caused by replacing them for decades to come.
Box profile sheets are ideal for livestock sheds, horse stables, and other agricultural buildings. This is partly due to how they absorb the sound or rain and debris from overhanging trees, especially when coated with either polyester or plastisol.
Bike sheds, pool houses, and other garden buildings can be easily covered by box profile roofing sheets. What’s more, a choice of colours allows it to blend in with the environment of your garden.
Box Profile Roofing Sheet Installation
When fitting box section roofing, it is vital that you follow the manufacturers step-by-step guide. This will ensure your sheets are weatherproof and safe, but ensuring they are overlapped appropriately and have the necessary support.
- Ensure you wear appropriate safety equipment to protect yourselves and others when installing these roof sheets. This includes suitable protective gloves, clothing, footwear and a hard hat.
- If you need to walk on your box profile sheets use crawl boards. Every effort should be taken to walk over the purlin supports as other areas of the roof deck may not be able to support your weight.
- You should only use tools that produce little heat when cutting these roof sheets, such as a circular saw with a fine-tooth blade. This is to prevent any damage to the polyester or plastisol coating.
- If you need to perform small cuts or create small openings, use a jigsaw or reciprocating saw. You can also use an angle grinder in some cases to cut box profile roofing sheets.
- Appropriately placed purlins should be used to support the weight of these roof sheets. Any joins or laps in the purlins should then be supported by a rafter, which can be fixed together with boltable cleats.
- If you are using multiple box profile sheets, they must be overlapped on all sides. It is also recommended that you use a lapping tape on the sides for increased weather resistance.
- Use foam fillers at the eaves of your roof to prevent water ingress and other weather-related issues. Ensure those used match either the 32/1000 or 34/1000 profile of your roof sheets.

Frequently Asked Questions
What Are Box Profile Roofing Sheets?
Although structurally similar to other metal roofing sheets, the box profile variety instead features distinctive box sections rather than the classic curved corrugations. The sheets are crafted using a robust combination of high-strength materials to provide exceptional levels of durability, impact and corrosion resistancee.
Box profile roofing sheets are usually spotted on agricultural buildings and commercial warehouses. This type of sheet typically boasts a 32/1000 or 34/1000 profile, though the sections can vary in width and height. See below for a graphic depicting the various sections of a box profile sheet.
Where Can You Use These Sheets?
Box profile roofing sheets have great versatility so can be used on virtually any roofing or cladding application between 10° and 90° in pitch. The structural properties and form make this type of roof sheet perfectly suited to agricultural buildings such as stables and bale storage. You may also see them commonly used in the construction of commercial warehouses such as distribution centres and storage facilities.
As box profile sheets are typically manufactured using 0.5mm and 0.7mm steel, they are significantly lighter than many alternatives (i.e. fibre cement). This lightweight build helps to considerably reduce the structural support required, although the sheets can weight in excess of 4.78kg per square meter.
How Much Do These Sheets Cost?
Starting at approximately £7 per square meter, box profile sheets may seem more expensive in comparison to alternative materials. However, in the long term, they produce significantly lower costs with virtually no maintenance required and an impressive life expectancy of 10 - 25 years dependant on the choice of coating.
£7 is the average starting cost, although the price can vary dependant on the thickness of the steel and the coating selected.
Which Coating is Best?
The choice of coating can have a significant impact on the strength, durability, longevity and appearance of your box profile sheets. We have partnered with trusted brands such as Hornsey Steel to offer these sheets in a selection of high-quality coatings including polyester paint and PVC plastisol. Let’s take a look at both to compare.
Polyester Paint Coated
Boosting life expectancy to 10-15 years, our polyester paint coating ensures excellent longevity and strength for your box profile sheets. This impressive coating provides top protection against weathering and minor scratches at no extra cost to you. It is available in a range of popular colours including black, green, grey, blue and white, giving you the freedom to create the perfect aesthetic for your building structure.
PVC Plastisol Coated
Robust and durable, our PVC plastisol coating provides added protection against harsh weathering and hard scratches to improve the lifespan of your box profile sheets by up to 10 additional years. Once again, this top-grade coating is available in a selection of attractive colours including black, green, grey, blue and white.
How Do You Cut Box Profile Roofing Sheets?
Firstly, we’d recommend cutting these sheets face down on a flat surface that’s raised off the ground by padded supports. This is for your own safety and using solid supports or cutting in situ raises the risk of damaging the structure of the sheets.
- Draw out the line you’d like to cut using a straight edge and a marker pen.
- Using a fine tooth blade, use a circular saw to very carefully cut along the edge you’ve marked.
- Rub along the cut edge with an emery cloth to smooth out the cut edge.
How Do You Measure Box Profile Roofing Sheets?
Due to the corrugations, it may seem a little confusing as to how box profile sheets should be measured. Thankfully, it is actually a very simple process.
All you have to do is measure the box profile sheet from one end to the other, as if the sheet were flat with no corrugations. This will provide you with the measurements you need.
Make sure you also don’t forget to measure the thickness as this may determine the strength and suitability of the sheets for varying applications.
What Thickness is Right for Me?
Our high-quality range of box profile roofing sheets are available in both 0.5mm and 0.7mm sheet thicknesses. But which of these is best for your project?
Generally, the difference between the 0.5mm and 0.7mm thicknesses comes down to the robustness of the roofing sheet. The 0.7mm sheets will typically offer a higher level of structural resilience and durability so are more suited to heavier duty roofing applications. The 0.5mm size does still offer a high degree of strength, however is usually better fitting for cladding wall projects.
