Blast Proof | Fire Resistant | Low Cost | Long Lasting | Heat Resistant

Doorsteel is a high impact heavy duty steel composite board manufactured with a fibre reinforced environmentally friendly high density calcium silicate & cement core, with outer facings of perforated galvanised steel, mechanically bonded to both outer surfaces. These boards are fire resistant up to 240 minutes and classed as non-combustible to BS 476: Part 4: 1970, BS EN 1716: 2010, BS EN 1182: 2010 and A1 to Clause 10 of BS EN 13501- 1:2002. Euro Class A1 and A1FL. Building Regulations stipulate minimum periods of fire protection required to the elements of a building’s structure. In the severest of situations, when protection is needed for up to 4 hours integrity and insulation.

 

Doorsteel High Impact Boards has been tested to meet this criteria in accordance with the requirements of BS476: Part 22:1987 and BS 476: Part 20-24 BS EN 1364-1 & 2. It also provides up to 3 hours for hydrocarbon fire barriers. The construction means the boards are exceptionally robust for harsh industrial and public environments.
