DIFFERENCE BETWEEN ALLOY 5000 AND ALLOY 3000
Aluminium alloy 5754 used for RIVERCLACK® has got mechanical and chemical characteristics far above the normal alloys 3000 used generally for metal roofing.
The use of alloy 5754 is advised in the UNI 10372 norm, related to metal roofing design, for the use in marine as well as in industrial environments, rather than other alloys.
The high hardening degree (H18) together with other features of the alloy 5754, with high magnesium content, used for RIVERCLACK® system, represent the right choice to have a light and resistant roof covering.
