# 1: THE WORLD’S LEADING METAL COATING TECHNOLOGY USED BY SAFAL STEEL IN SOUTH AFRICA
Steel is still considered as one of the most cost effective of all building materials. But steel rusts readily and if used in exposed conditions, needs to be coated to protect the inner steel core against corrosion and premature failure.
A coating of aluminium/zinc/silicon (in the ratio of 55% Al – 43,4% Zn – 1,6% Si) is the most widely used, widely proven and versatile coating alloy in the world, used for the protection of carbon steel.
Generically called AZ or Aluzinc coating, brand names used internationally include Galvalume and Zincalume. In South Africa, the name Zincal® identifies the material made by Safal Steel. Colour-coated Zincal® is sold as Colorplus® or Optima® in an array of durable and beautiful colours.
Safal Steel is the only producer of AZ-coated steel in Southern Africa. The company started production in 2010, and ten years down the road, has a proud track record of project installations which have outperformed even the initial expectations of service life.
A free CPD presentation on “Advanced coated steel technology for roofing and allied application” is available for architects.
