For a strong, bold and modern appearance, IBR is South Africa’s top roofing profile; durable, cost-effective, pre-painted sheet with optimal performance & value. Inspired by the vibrant colours of Africa, IBR 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 sacrifices itself to protect the steel at cut edges.
