Application

Designed for fire resistance and impact resistance in public and service corridors, warehousing, industrial buildings, mass transit systems, manufacturing facilities and other areas subject to abnormally rough use. Also designed for blast resistance to off-shore facilities, petro-chemical industrial facilities, gas processing plants and other areas subject to projectile or explosive risk.

Description

A composite board manufactured with a fibre reinforced cement core, with outer facings of 0.5 mm perforated galvanized steel mechanically bonded to each surface 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 lightness, strength, impact resistance and durability with exceptional fire resistance. These systems remain resistant to firefighter hoses leaving the board capable of performing their function should fire services be required to withdraw before a fire is extinguished.

DURASTEEL® systems have been used successfully for many years, including rail and metro projects, military facilities and in commercial, pharmaceutical and petrochemical plants.


Features and benefits:

  • 60–240 minutes' fire protection.
  • Hydrocarbon tested.
  • High impact resistant.
  • Blast resistant.
  • Moisture resistant.
  • Fit and forget system.
  • 40+ year service life.
  • Fast installation.
  • Can withstand prolonged cellulosic, hydrocarbon or jet fire and hose-streams from firefighting.
  • The steel laminated boards can be left untreated in galvanized finish, or decorated with water or oil-based paints.
  • The surface spread of flame properties may be negated when the boards are decorated
