Steel Structure (Welded/ Bolted)

Steel structure is a metal structure which is made of structural steel* components connect with each other to carry loads and provide full rigidity. Because of the high strength grade of steel, this structure is reliable and requires less raw materials than other types of structure like concrete structure and timber structure.
In modern construction, steel structure is used for almost every type of structure including heavy industrial buildings, multi-storey buildings, equipment support systems, infrastructure, bridges, towers, airport terminals, etc.
Structural steel is steel construction material which fabricated with a specific shape and chemical composition to suit a project’s applicable specifications.
Depending on each project’s applicable specifications, the steel sections might have various shapes, sizes and gauges made by hot or cold rolling, others are made by welding together flat or bent plates. Common shapes include the I-beam, HSS, Channels, Angles and Plate.

Main structural types

  • Frame structures: Beams and columns
  • Grids structures: latticed structure or dome
  • Pre-stressed structures
  • Truss structures: Bar or truss members
  • Arch structure
  • Arch bridge
  • Beam Bridge
  • Cable-stayed bridge
  • Suspension bridge
  • Truss bridge: truss members
