Corrugated Roofing Sheets
Galvanised Steel Corrugated Roofing Sheets — Three Profiles, Cut to Length
Our corrugated steel roofing sheets, originally as "wriggly tin" are one of the UK's most trusted roofing materials. Highly durable, cost-effective, and straightforward to install, they are the ideal solution for agricultural buildings, industrial units, garages, outbuildings, and side-cladding applications.
We supply three distinct traditional profiles, manufactured from robust galvanised steel and available in plain galvanised, smooth polyester paint, or heavy-duty PVC Plastisol finishes:
- 13.5/3 Profile – Offers a 991mm cover width after lapping. This is our widest corrugated option, ideal for maximising speed of coverage on larger agricultural and industrial roofs.
- 10/3 Profile – Offers a 762mm cover width after lapping. A highly versatile standard profile that strikes a perfect balance between traditional looks and efficient coverage.
- 8/3 Profile – Offers a 610mm cover width after lapping. This narrow-fit traditional profile is excellent for smaller outbuildings, bespoke claddings, or projects with tight spatial dimensions.
Each cover width is designed to provide optimal span coverage, with an additional overlap to ensure a secure and weather-resistant installation.
