Box Profile Roofing Sheets

Box Profile Roofing Sheets by Cladco are manufactured from high-quality Galvanised Steel Sheets and are supplied in two different Profiles and thicknesses - 32/1000 Box Profile and 34/1000 Box Profile, both of which are available in 0.5mm and 0.7mm thicknesses.

Both 32/1000 and 34/1000 Box Profile Sheets are commonly installed on commercial, industrial and agricultural buildings alike, as either a roofing or side cladding material - making for a modern alternative to older corrugated-style roofs.

Steel Roofing Sheets are manufactured to order from our Devon-based warehouse and can be custom-cut to specific lengths to suit your project's needs. Sheets are available in a variety of Coatings and Colours for increased durability and aesthetic appeal, whilst their lightweight yet robust structure makes for a quick and easy installation.

32/1000

Cladco 32/1000 Box Profile Roofing Sheets feature 6 profiles across the entire Sheet, each with a 200mm profile pitch and 32mm profile depth, providing a 1000mm cover width when lapped.

Sometimes referred to as Box Profile Single-Skin Sheets, 32/1000 Roof Sheets have lower and fewer profiles when compared with our other metal Roofing Sheets, and feature a small rib that runs parallel between each profile for added strength and durability.

34/1000

Cladco 34/1000 Box Profile Roofing Sheets feature 7 rigid profiles of a 34mm depth across the entire width of the Sheet - one profile more than our 32/1000 option. Each 34/1000 Box Profile Roof Sheet will provide a 1000mm cover width when lapped, and can be manufactured in up to 9-metre lengths depending on the thickness of the Sheet used.

This Profile is the most popular product among our Box Profile Sheet styles, thanks to its wide range of uses and high tensile strength.

Both 32/1000 and 34/1000 Box Profile Roofing Sheets are produced in either 0.7mm or 0.5mm thicknesses, depending on their end-use. If being used as Metal Wall Cladding on the side of buildings, we would recommend using our 0.5mm Sheets as they are a lighter profile for installation on walls, and so do not need to provide the extra support to any load-bearing weight as a Sheet would when installed on the roof.

Advantages of Box Profile Sheets

Cladco Box Profile Steel Roofing Sheets are a hard-wearing and corrosion-resistant Metal Roofing option that can be cut to custom lengths to suit your requirements* in our Okehampton warehouse, based in the heart of Devon. *The maximum length for 0.7mm thick Sheets is 9 metres and for our 0.5mm thick Sheets is 7 metres.

The multiple rigid profiles across the entire width of both Box Profile Sheets provide additional high tensile strength to the already robust Steel Sheets, whilst the additional parallel rib on our 32/1000 Box Profile improves rigidity. Both Profiles provide excellent rainwater run-off and prevent any leaves and debris from building up on your Roof in poor weather conditions, due to the individual troughs the pitch of the Profiles create.

When used in Roofing applications, construction can be safely undertaken down to a pitch of 4 degrees using Self-Drilling Screws.

For additional strength, a range of Coatings including PVC Plastisol and Polyester Paint can be applied to the Sheets during the manufacturing process, to improve longevity, durability, and add aesthetic appeal.

32/1000 and 34/1000 Box Profiles can also be used as Metal Side Cladding Sheets and make a contemporary alternative to more traditional cladding materials such as timber or slate tiles. As well as their competitive price, their excellent longevity (when Coating is applied) and low-maintenance properties create a cost-effective steel cladding solution for your home or building.

Cladco Box Profile Roofing Sheets offer a 1 meter/1000mmm coverage when lapped, providing more roof breadth when compared with alternative roofing brands on the market. Their lightweight profile makes for a quick and easy-to-fit installation with minimal tools. Install Box Profile Roofing Sheets for your next roofing or cladding project to create a stylish, modern alternative to traditional materials.

34/1000 Box Profile

PVC Plastisol

PVC Plastisol is a 200-micron thick coating of high-quality PVC, with an embossed leather grain finish. The Coating is applied to the Steel Roofing Sheets during the manufacturing process.

The outcome of this improves the strength and longevity of the Sheet, and adds a lifespan of typically 15-25 years to the first maintenance or repaint, with a life in excess of 40 years in normal environments. PVC Plastisol also improves the Sheet's resistance to scratching, weathering and any external damage.

PVC Plastisol produces a Sheet with excellent climatic and UV protection, together with abrasion resistance and high strength. Cladco provides a comprehensive choice of eleven colours, allowing building aesthetics to be matched to the surrounding environment. These colours include: Anthracite, Black, Chestnut, Goosewing Grey, Slate Blue, Vandyke Brown, Merlin Grey, Juniper Green, Moorland Green, Olive Green, and White.

Polyester Paint

Polyester Paint metal sheeting is manufactured from a 25-micron thick, smooth enamel-coated steel sheet, which is economic to use and gives excellent weather resistance and longevity of typically 8 to 12 years to the first maintenance or repaint, with a life in excess of 20 years in normal environments.

We provide a choice of five colours in our Polyester coatings to suit your design needs, allowing you to be sympathetic to the surrounding environment with your colour choice. These colours include: Slate Blue, Juniper Green, White, Black and Light Grey

The reverse/internal surface of the Polyester Box Profile Roofing Sheets is coated with a standard alkali grey wash coat.

Galvanised

The coated steel strip we form into Roofing Sheet Profiles and Flashings is produced by leading suppliers, giving us quality control and traceability of the material we use. To produce high-quality, pre-coated Sheeting, a system of multi-layered coatings is applied to a zinc-coated, high-tensile steel strip and oven-cured to ensure optimum adhesion.

For further information on Coatings, take a look at our Coatings information page.

Dripstop Anti-Condensation Box Profile Option

What is Dripstop? Dripstop is an anti-condensation adhesive felt membrane that is applied to all our Box Profile Roofing Sheets during the manufacturing process. Dripstop Condensation Control is a proven solution to preventing drips from forming on the underside of your Roofing Sheets, especially in conditions of high humidity and lack of airflow.

How Many Sheets Do I Need?

When it comes to planning a Box Profile roofing project, our handy Roofing Sheet Calculator will guide you through how many Sheets to order, as well as what potential Flashings and Accessories you may need, and will provide the total cost of your upcoming project.

Installing Your Box Profile Roofing Sheets

For a single-pitch Box Profile roof, the minimum pitch we recommend is 4-5 degrees to lay Box Profile Sheets in runs. Make a start at the eaves and in the corner away from the direction of the prevailing wind to prevent water ingress and side laps facing into the wind. Adjustments will have to be made regularly if the first Sheet is not laid perpendicular to the eaves and ridge - something that may be unavoidable if the building is not square.

For more information and further installation help and advice, take a look at our 32/1000 Installation Guide and 34/1000 Installation Guide, or visit our Roof Help and Advice page.

Additional Materials

Roof Flashings are designed to seal and finish the ends and corners of a run of Box Profile Sheets, helping to protect against water intrusion as well as being an integral component of the roof. Flashings are also a great way to enhance the aesthetic appeal of your project.

Cladco also stock a selection of Roofing Accessories and Purlins that both complement and support your Roof structurally, helping to achieve a professional and durable finish. Accessories include Screws, Screw Caps, Foam Fillers and more.

Roof Lights for Box Profile Roofing

Cladco 34/1000 and 32/1000 GRP Roof Lights are manufactured from heavy-duty 1.5mm thick translucent GRP (Glass Reinforced Plastic) materials and will let in daylight through at a transmission rate of over 80%.

Their width and profile match that of our Box Profile Metal Roof Sheets, ensuring these translucent Roof Light Panels can be installed seamlessly alongside our Box Profile Roof Sheets. GRP Translucent Roof Lights are available in lengths of 2.5m, 3m and 3.5m.

Insulated Box Profile Panels

32/1000 Box Profile Insulated Panels are perfect for cladding both walls and roofs. Insulated panels are sold in set lengths from 2.5m up to 6m, providing an off-the-shelf insulated roof panel that’s easy to fix seamlessly with our 23/1000 Box Profile Sheets and help to prevent condensation.
