Inspired by the vibrant colours of Africa, OPTIMA® is the brand of choice for durable, cost-effective, pre-painted steel roofing. OPTIMA® is produced by a unique process whereby rolled steel is continuously hot dipped into a patented alloy of 55 Aluminium 43 5 Zinc and 1 5 Silicon.
THIS PATENTED COATING PROTECTS THE STEEL IN TWO WAYS:
- The Aluminium component of the coating provides a tough physical barrier between the external atmospheric conditions and the inner core of steel.
- The Zinc in the coating protects the steel at cut edges.
