T18 box profile steel, gloss cherry red RAL 3005, cut to length

Trapezoidal steel sheets are a practical choice for roofs and façades where fast installation and a manageable cost matter. The repeated ribs stiffen the sheet and give the surface a regular pattern. SteelProfil helps select a profile for a garage, shelter, hall, outbuilding or modern façade, balancing technical needs with the desired colour.

Trapezoidal profiles suit large surfaces because the sheets cover one bay after another quickly. The geometry suits industrial buildings and, in the right colour, can also be part of a contemporary design. Select roofing or cladding sheets to match the intended use and the rib arrangement specified in the design.

• Profiled sheets can cover large areas of roof or wall quickly.
• Different profile depths suit different structural requirements.
• The choice of finishes makes it easier to coordinate the roof with the façade and surroundings.

Rib depth, steel thickness and support spacing all affect how a sheet behaves under load. For a roof, consider the structural design, the pitch and the requirements of the selected system. Low weight helps with transport and handling, and opens up options for refurbishment. For an existing roof, assess the condition of the structure and the whole build-up before choosing a covering.

Choose surface protection to suit the surroundings. A householder’s garage may call for a different finish from a warehouse wall or farm shelter. Options include galvanised, metallic-coated and colour-coated sheets. We can compare these finishes against the service requirements and the flashings needed at eaves, ridges and corners. On a façade, the rib direction can emphasise height or length; plan the sheet layout around windows and gates.

SteelProfil offers first- and second-grade trapezoidal sheets, including stock batches that can help get work started quickly. Compare lengths, effective coverage and the condition of the faces. Assess each second-grade batch against the requirements of its intended location. Well-chosen sizes reduce cutting and help you use more of the steel you buy.

Promotions and competitive prices make it possible to put together a covering and its accessories within budget. For a simple shelter, calculate the number of sheets from the roof layout; for a façade, include openings and the direction of the joints. We can draw up the schedule and help choose fasteners and flashings. The quotation sets out the material cost so you can compare suitable profiles for your project.
