Frequently Asked Questions

Coverage is the cover width of each sheet once it is fitted and overlapped. Our CS32/1000 box profile has a nominal cover width of 1008mm, our CS34/1000 has 1000mm and our 3” corrugated roofing sheets have 990.6mm. Please ask a member of staff to confirm sheet quantities if needed, or use our calculator.

Traditionally our roofing products are overlapped by one profile. This is on both the box profile roofing sheets and 3” corrugated roofing sheets. They can be overlapped by another profile, but this means more sheets will be required to cover the area. See our guide to overlapping metal roof sheets.

The 32/1000 box profile roofing sheets are fixed on the flat of the sheet, known as the trough, normally through the middle between the two ribs. The 3” corrugated roofing sheets differ by being fixed through the top of the curvature. It is recommended that stitchers are used on the overlapping edge. See our roof fixings and our guide to fixings for steel roof sheets.

There is no minimum length of sheet. The maximum length that Cardinal Steels is able to handle and deliver is 10 metres. Longer lengths are available but not recommended and would be on a collection basis only. GRP roof lights can be cut to length up to 6.1m.

No job too big, no order too small. Use our calculator to build a quote for any size of job.

If there are no off-loading facilities, the sheets must be carefully unloaded by hand. Our drivers are helpful and more than willing to help. Confirm the offloading arrangements when you order, and see our delivery information.

We are always happy for customers to collect from our Bromsgrove facility and meet our staff. Please bring a vehicle capable of carrying the full sheet length safely, and confirm the arrangement with us when you order. Delivery is usually preferred, as hand-balling materials into vehicles can scratch or damage the coating. See our delivery information.

Always wear gloves when handling roofing sheets, as the edges can be very sharp. Try to lift one sheet at a time because of the weight. All our flashings come with welted edges as standard to help with this.

We recommend that all first orders include a colour sample sent by post. Colour matching between different mills and countries of origin is a common problem in the roofing and cladding industry. Our online colour chart is as close as we can digitally get, so request a free sample or ask a member of staff for any colours you need.

Cardinal Steels do offer touch-up paint. This paint is as close to the selected colour as we can get, but it can dry a slightly different shade. We would always recommend plastisol coated sheets, as this coating is a lot more durable than polyester and less susceptible to scratches.

Cardinal Steels don’t offer an in-house installation service, however we do have recommended installers across the UK mainland who can price the work for you. Contact us for details.

A clad roof is a roof covered with cladding: profiled sheets fixed over the roof structure to form a weatherproof outer layer. Cardinal Steels makes steel roof sheets in corrugated, box profile and tile effect profiles, in galvanised, polyester and plastisol finishes.

It depends on the profile, thickness, finish and length, because every order is made to size. Use our calculator to build a quote, or contact us and we will price it for you.
