What is Durasteel?

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’ 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 and ceiling applications, with a wide range of specifications available.

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

Where is Durasteel Used?

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.



Our decades of industry experience and global presence mean we’ve worked with some of the world’s leading brands and service providers. Our end-clients include Transport For London (London Underground), London Heathrow Airport, Dubai Metro, Qatar Rail, Dubai International Airport, NATO, Saudi Aramco, the Bank of England and UK Power Networks, to name but a few.
