Curved sheets

Barrel and arched roofs, canopies and walkways
Crimp-curved sheets for curved eaves and ridges
Made from standard WS trapezoidal profiles
Same coatings and colours as flat sheets

Curves without joints

Curved sheets turn a roof into an arch with no ridge joint – for canopies, walkways, sports halls and architectural roofs. Two methods are used:

Two ways to curve a sheet

Roll-curved (smooth) sheets – bent to a large radius for barrel roofs; chord length up to about 1.2 m per curved piece in the reference range, longer arches assembled from several sheets.
Crimp-curved sheets – crimped to a tight radius (minimum radius about 300 mm, minimum length about 560 mm) for curved eaves, ridges and bullnose details.

Achievable radii depend on profile, thickness and coating – confirm with our engineers before design.

자주 묻는 질문

Which radius can be achieved?

Crimp-curved sheets reach a minimum radius of about 300 mm; smooth roll-curved sheets need larger radii. The exact limit depends on profile and thickness.
