Wall and roof cassettes manufactured by Blachotrapez are a technically advanced product intended as the external wall layer. They are perfect for covering of large surfaces. Their main applications include finishing of production halls, shops or office buildings. Covered structures gain a solid and enduring protection with a modern look. Lightness and profiling make for quick and easy mounting. Wall and roof cassettes are made of organic-coated galvanised steel tapes. Thanks to robust raw materials, they provide protection against weather impact, fire and noise. With a wide colour selection, cassettes may be adjusted to the type and appearance of the building. The product is complemented by a traditional troughed metal sheet with a set of fixing and sealing accessories. The advantages of this solution include low weight and profiles for quick and easy mounting, regardless of the covered surface. Blachotrapez wall cassettes are also used for building renovation purposes.
