Certificate type
A composite panel of fibre-reinforced cement with punched steel sheets mechanically bonded to both outer surfaces.
DURASTEEL® is a composite board manufactured with a fibre reinforced cement core, with outer facings of 0.5 mm thick perforated galvanized steel sheet mechanically bonded to both outer surfaces of the core. Other steel finishes such as stainless steel are also available for use where greater resistance to corrosion is required. DURASTEEL® systems combine strength, impact resistance and durability with up to 240 minutes fire resistance. These systems remain resistant to firefighters hoses leaving the boards capable of performing their original function even in the aftermath of a fire.
