Open Web Steel Joists, Curved Built Up Members

OPEN WEB STEEL JOISTS
The Open Web Steel Joist is a secondary steel truss member fabricated from crimped angles welded onto top and bottom chords. The elements of the open web joist are made of hot rolled as well as cold formed grade 50 roof purlins, among others.

Advantages

  • Offers an economical solution for long span carrying heavy load or light load compared to conventional steel structure.
  • Allows more clearance to the building by minimizing the mezzanine overall depth by designing beam at the short direction and the joists at the long direction without increasing the weight.
  • Ducts and mechanical accessories can be installed in between the web openings.
  • Cambering prevents tiles, partitions or any other delicate finishing from cracks by maintaining the finish floor level straight.
