Durasteel is a composite panel of fibre reinforced cement mechanically bonded to punched steel sheets on both surfaces. It is classified as non-combustible in accordance with many international standards. Durasteel is also highly resistant to moisture even when saturated. It will not absorb combustible fluids and its fire resistant qualities are exceptional.
Durasteel is highly impact and blast resistant, which enables it to withstand prolonged exposure to fire of the celluloid, hydrocarbon or jet fire types. It can also withstand hose-stream actions and, because of its very low moisture absorption, it can be used externally and is not susceptible to the damage often caused by moisture during the early stages of delivery and installation of the system, or by sprinkler actuation.
