BPA galvanised flat steel, matt polyester — RAL 7016 8017 9005

Flat sheet can be shaped into components that a standard fitting cannot replace. With the right sheet, a fabricator can make roof flashings, window sills, covers and façade trims. It is a staple for roofers and sheet-metal workers, and useful for repairs and workshop jobs. SteelProfil offers sheets that can be matched to both the shape and the finish required on a particular part of the building.

Flat sheet can be cut and folded to suit the job. The installer can make an eaves flashing, verge trim, chimney flashing or parapet cap to the actual dimensions of the building. This gives the roof a neat finish and avoids improvised joints. The material suits one-off pieces as well as runs of identical components for larger projects.

Galvanised, aluminium-zinc coated and colour-coated sheets differ in appearance and performance. A coloured finish can match the roof, window frames or façade. Matt, gloss and decorative finishes offer different effects. Consider thickness, formability and how the coating will withstand local exposure. A suitable sheet gives the detail the stiffness it needs without unnecessary weight or cost.

Flat sheet is used for cover strips, eaves flashings, sandwich-panel joint covers, wall abutments and trims around openings. Workshops also use it to make housings and parts to drawings. Its small thickness makes it easy to fit accurately. Each component should still be formed and fixed so that it directs water where intended and remains stable in service.

Before buying, draw the unfolded shapes and work out how many pieces fit on each sheet. This reduces waste and makes it easier to compare sheet sizes by price. Choose fasteners and seals for the substrate. Cut coated sheet with the manufacturer’s recommended tools and remove swarf from the surface. Careful fabrication protects the coating and the appearance of the finished parts.

Measuring and making flashings to fit is particularly useful on older buildings and unusual junctions. The installer can make the part on site or in the workshop from measurements taken on the building.

SteelProfil offers first- and second-grade flat sheets, with selected sheets available from stock. For second-grade material we can help assess the characteristics of the batch against the details you plan to make. Promotional lots can be useful whether you need a single flashing or a longer production run. Ask about sizes, thicknesses, colours and current availability. We can help you choose a sheet or, if you need finished pieces, a suitable item from our flashing range.
