THE IDEAL COATING OF FASTENERS FOR OUTDOOR STRUCTURES
Using timber, it is possible to build outdoor structures that meet both functionality and aesthetics. However, the right products are needed: our C4 EVO screws, certified for outdoor use in service class 3 and atmospheric corrosivity class C4, ensure very high performance in terms of resistance to corrosion typical of coastal areas and aggressive environments, while maintaining the mechanical performance of carbon steel.
C4 EVO coating is a multilayer coating composed of an external functional layer of epoxy matrix with aluminium flakes of around 15-20 μm, which gives the coating optimum resistance to mechanical and thermal stresses. The aluminium flakes also serve, when required, as sacrificial cathodes for the metal base of the screw.
