Trapezoidal sheets belong to the group of high-profile trapezoidal sheets, which gives them high strength. This feature has led to the widespread use of trapezoidal sheets in construction, including in the construction of large-scale industrial and commercial facilities, as they play an active role in load-bearing. Construction profiles, like low-profile trapezoidal sheets, are characterized by a trapezoidal cross-section; however, they have a significantly higher rib height, which is denoted by the letter T followed by a number corresponding to the rib height in mm. For this product group, the sheets range in height from T50 (50 mm) to T200 (200 mm). Structural steel designed to withstand high stresses, such as S 320 GD and S 350 GD, is used in their production . Most often, these are galvanized sheets, which may additionally be coated with protective and color-enhancing coatings, such as polyurethane.

The products manufactured by the Blachy Pruszyński Company are characterized above all by the excellent properties of the sheet metal used in their production. Our company’s trapezoidal construction sheets comply with the harmonized standard EN 1090-1, have a Declaration of Performance, bear the “CE” mark, and hold a ZKP certificate, which allows them to be freely used in construction throughout the European Union. Among the most highly valued advantages are:

• A wide range of options: profile heights from T50 to T200 (and higher—upon special request), making them suitable for a variety of applications
• varying thicknesses of the trapezoidal sheets used (from 0.5 to 1.7 mm)
• set of accessories, including: screws, nails, gaskets, anti-condensation nonwoven fabric
• the ability to make perforations
• Favorable performance characteristics: effective coverage width
• Standard coating options include: glossy polyester, zinc, and aluzinc, which enhance the functional (weather resistance) and aesthetic qualities of the structures
• the product’s light weight, which speeds up assembly
• an attractive price.

The strength of individual models is influenced by the height of the corrugation, the thickness of the sheet metal used, and the spacing of the supports, all of which should be specified in detail in the design. Permissible load tables and assembly instructions developed by our company assist in the design and assembly of trapezoidal sheets, thereby eliminating the need for labor-intensive calculations of the effective geometric characteristics of thin-walled products with complex shapes.

What factors should you consider when choosing construction sheets?

The main criterion for selecting construction sheets should be where and how they will be used. It’s worth reviewing the manufacturer’s product lineup and consulting with technical advisors to choose the right product, as certain models are better suited, for example, for the facade of an industrial or commercial building, others as structural wall components, and still others for roof coverings.

Other factors to consider include the profile height and the type of protective coating applied to the structural trapezoidal sheet metal. The latter factor ensures that the sheet metal retains its functional properties even after many years of use. For these reasons, it is worth relying on reputable manufacturers who provide valuable technical support and offer a long-term Warranty on their products.
