DuraSteel

 

 
DuraSteel is  a unique non-combustible material consisting of two metal sheets mechanically bonded to a cement fibre core.  DuraSteel is lightweight and used in the construction of fire and blast resistant barriers, ductwork, enclosures and structures. 

DuraSteel is exceptionally robust, resistant to impact, unaffected by moisture and once installed requires minimal maintenance even in the most aggressive atmospheres.

 
DuraSteel sheets have a variety of uses. DuraSystems offers a complete line of fire and/or blast resistant systems. Click along the left hand column for further details on some of our other systems.



Whether for fire or blast, some of the most common systems utilizing DuraSteel are:

  • Fire Rated Ventilation Systems
  • Fire Rated Ceilings, Floors, Walls & Door Assemblies
  • Oil, Gas Pipe & Cable Tray Enclosures
  • Fire Barriers
  • Outdoor & indoor transformer fire separations
  • Protection from hydrocarbon fires & blasts
  • Fire & Blast containment for gas storage
  • Oil & Gas Compressor protection
  • Portable Barriers
  • Document Storage Vaults
  • Acoustic Barriers & Enclosures
  • Blast Walls & Doors
  • Blast Resistant Duct
     
The sheets come 1.2 x 2.5 meters (approximately 4 x 8 feet) in size and are available in the following options:
  •    Standard 3/8" (9.5mm) thickness
  •    Optional 1/4" (6mm) thickness
  •    Standard G-90 galvanized finish
  •    Optional 316 – 2B stainless steel finish
  •    Other specialty metals available

DuraSteel is by far the most extensively tested material in Passive Fire Protection. DuraSteel and assemblies constructed of DuraSteel have been widely tested by independent laboratories.


DuraSteel and DuraSteel assemblies have been tested for the following characteristics:

  •    Combustibility
  •    Fire protection (6hrs of fire resistance in relation to ASTM E119 time temp curve)
  •    Hydrocarbon fires (H0, H60, and H120)
  •    Jet fire
  •    Blast protection
  •    Impact resistance
  •    Physical strength
  •    Hose stream
  •    Negative and positive pressure testing
  •    Acoustical reduction testing
  •    Frost cycling and resistance
  •    Radio frequency shielding
  •    Thermal conductivity

Independent testing laboratories and authorities providing certification include:

Why is Passive Fire Protection Important?

  

A major fire can have a devastating affect on both property and people.  Although active fire protection such as sprinklers put out a fire, the smoke from the fire remains. This smoke can be harmful when not properly mitigated. Ventilation systems offer an effective method for the control of smoke.

Smoke can behave very differently in tall buildings than in low buildings. The predominant factors that cause smoke movement in tall buildings are stack effects, the effect of external wind forces, and forced air movement within the building. Smoke removal and venting practices are complicated by stack effects, which will tend to favour natural air movement vertically through the building as a result of differences in temperature and densities between the inside and outside air. 

Pressurization and smoke exhaust systems are methods of controlling the smoke in the event of a fire.  Life safety systems such as these are required to be fire rated so that service they provide will be continued in the event of a fire.
