Durasteel enclosures provide protection against fire to cable ducts and general building services in accordance with the relevant criteria of BS 476: Parts 20: 1987 and 22: 1987. Durasteel systems are suitable for providing protection to services even under extremely aggressive environments.
The Durasteel systems described below ensure the integrity of fire compartments if the services are required to continue functioning in the event of fire.
The maximum permissible dimensions for enclosures are up to 3000mm x 1500mm for up to 240 minutes fire resistance. For hanger sizes, please contact us.
