Durasteel is a four-hour fire and blast resistant composite panel of fibre reinforced cement mechanically bonded to punched steel sheets on both outer surfaces.

It is classed as ‘non-combustible’ according to BS 476:Part 4:1970 and to Clause 10 of EN 13501-1:2002, and has been tested to comply with many recognised UK and international fire standards.

Durasteel has been developed and supported through rigorous testing for use in barriers, doors, hatches, ceilings and ducts, among other applications, with a wide range of specifications available.

Durasteel systems combine lightness, strength, durability, a small footprint and rapid installation with exceptional fire, blast, impact and acoustic resistance. These systems also remain unaffected by firefighters’ hoses, leaving them capable of performing their original function even during a fire.


Durasteel has been installed extensively around the world across a wide range of industries, including power stations, nuclear, petrochemical, pharmaceutical, off-shore platforms, warehouses, airports, rail and metro facilities.

Durasteel can be designed, supplied and installed in a variety of system types, including barriers, ceilings, enclosures, ducts and doors, providing up to four hours of fire compartmentation, insulation, blast resistance, impact resistance and more.

Systems can also be designed on a bespoke basis according to project specification requirements, including custom colour schemes and branding.
