COLORBOND® Ultra steel is the ultimate choice for an attractive and long-lasting steel roofing material that offers excellent protection against severe environments. COLORBOND® Ultra steel has been developed primarily for environments in close vicinity to sea, laden with salt spray in the air. The combination of protective coatings and the production process makes it one of the most cost effective and corrosion resistant materials available. From severe natural to industrial environments, COLORBOND® Ultra steel is one of the most effective building material discovered to combat these harsh conditions. It comes with a 200 g/m2 (AZ200) metallic (55% Al-Zn alloy) coating, which means for every square metre of steel, there is a minimum of 200 gram of 55% Al-Zn alloy coating. With the higher metallic coating class and the unique protective paint system, COLORBOND® Ultra steel is one of the most cost-effective building materials available for harsh environments with other benefits of paint durability as in case of COLORBOND® steel.
