DURASTEEL® systems combine lightness, strength, impact resistance and durability with exceptional fire resistance. These systems remain resistant to firefighters’ hoses, leaving them capable of performing their original function even in the aftermath of a fire. DURASTEEL® systems have been used successfully for many years, including rail and metro projects, military developments and in commercial, pharmaceutical and petrochemical facilities.

Construction:

• Perimeter channels fastened to surrounding construction with M10 or M12 all-steel expanding anchors (or equivalent) at 500 mm maximum centres.

• Vertical channels at maximum 1200 mm centres. Horizontal and vertical channel members either welded together or joined with steel angle cleats, minimum 60 mm x 60 mm x 3mm thick x 60 mm long, fastened to each channel member with two M10 steel bolts and nuts.

• (For barriers with insulation only) 9.5 mm DURASTEEL® fillet fixed on both sides of channel. Fillet strips to overlap channel by minimum of 20 mm on both sides.

• Single layer of 9.5 mm DURASTEEL® fixed on one side of channel with M5.5 steel self drill and tap Tek screws at 250 mm nominal centres. Fixings a minimum of 12 mm from edge of sheet and a maximum of 50 mm from corners. Length of fixing to be sufficient to ensure appropriate penetration of screw thread in accordance with screw manufacturer’s recommendations.

• Vertical board joints coincide with studs, horizontal board joints are backed by steel channel the same size as the vertical studs.

Dimensions:

Channels up to 6 m are 80 mm x 60 mm x 3 mm.

Fire resistance:

• Fire barriers have 240 minutes integrity.

• All fire barriers are resistant to fire attack from either face.
