Steel Truss Floor Deck

BRD Steel bar truss floor deck is the integrated fabricated formwork for which steel bar is to be processed into steel bar truss and then the steel bar truss is to be welded with galvanized profiled sheet. In the construction stage, the steel bar truss floor deck has features such as economy, convenience, safety, and reliability, etc and it has been widely used by structure and building fields, such as multilayer workshops, multilayer, high –rise and ultra-high steel structure buildings and various irregular floor, concrete structures and high speed railway, etc.

1.Unique double folding design
Effectively increases board edge strength, it hard to bend or deform during transportation and construction. Allows for easy fastening at the bottom.
2.Improved form spot welding technology
Original form spot welding equipments are improved to make welding current of many welding heads more balanced and stable, so the floor deck will be free from cold joints or weld penetration phenomenon.

Economic

The load-bearing of the truss is able to support weight without added structures that could add to the cost of construction.

Convenient

Field steel binding is reduced by 60-70% and construction is much quicker.

Safe

The mechanical property is basically the same as a traditional floor slab with increased crack resistance. The bottom die is not loaded in the use phase, eliminating fire and corrosion risks.

Reliable

The reinforcements are arranged uniformly. The two-way stiffness of the floor slabs are similar which is conducive to seismic stud welding.
