DURADUCT®

High impact, fire and blast resistant duct systems made from DURASTEEL® sheets, delivering a fit and forget system for the life of the building.

The DURADUCT® range includes:

  • DURADUCT® LT: a galvanised steel inner duct overboarded with 6.0mm DURASTEEL® and finishing trim angles. An economical fire resisting ductwork solution combining the airflow and wipe down characteristics of standard galvanised steel ductwork with impact and blast benefits of DURASTEEL®.
  • DURADUCT® SMT: formed by fixing 9.5mm, DURASTEEL® sheets onto a welded or cleated, prefabricated steel skeletal framework, minimum 3mm thick. Tested to provide high levels of blast and fire protection. Uniquely suitable for potentially explosive environments such as electrical transformer and switchgear rooms.
  • DURADUCT® SR: is used together with the DURADUCT® LT and DURADUCT® SMT ranges for connection largely between the main smoke extract system and grilles where fire insulation performance is not required.

These systems remain resistant to firefighters’ hoses, leaving them capable of performing their original function even in the aftermath of a fire.
