The Durasteel Duraduct Ductwork system is designed to provide high levels of both fire and blast protection, making the system uniquely suitable for potentially explosive envuronments such as transformer and switch gear rooms. It is also tried and tested in ductwork solutions for smoke control, smoke exhaust, fresh air ventilation, pressurisation riser shafts, lift-shaft protection and protection of power cables and services.

The Duraduct system is formed by fixing 9.5mm Durasteel sheets onto a welded, prefabricated steel framework and can be constructed in 2, 3 and 4 sided configurations.
