Recommendation

Steel is the most clever choice for roof decking supports, thanks to its lightness and mechanical properties. The steel decking support the roof elements but does not provide the weatherproofing layer. Steel grade, dimensions and zinc coating mass must be selected according to the construction regulations (European and country standards). Risk of corrosion depends on the internal atmosphere.

Farms require a high performing coating to ensure a long life time, that classical metallic or organic coated steels can not satisfy. Therefore, selection of the coating must be made based on the atmosphere requirements. A minimum coating mass of 275g/sqm (or equivalent) for Granite^® Farm substrate, and 310g/sqm for Magnelis^® is required .
