The combination of hollow structural composite profiles and laser welding technology will bring a whole new world of possibilities.

Peak Kong Special Steel has launched composite hollow structural profiles for the market. The combination of square tubes and round tubes is fused using laser penetration welding to create a new type of composite hollow structural profiles.

Composite hollow structural profiles have excellent structural load-bearing capacity, weldability, toughness and impact resistance, which improves the complex design performance of buildings. They are suitable for large-span, lighter structural parts, smaller cross-sections, and greater load-bearing capacity. .

Compared to cold-formed hollow profiles and thermoformed hollow profiles, composite hollow structural profiles offer new possibilities, including:
  • High design flexibility
  • steel and steel combination
  • Smaller cross-section and large load-bearing capacity
  • more complex structures
  • Composite profiles can increase the overall profile size and create more complex geometries. According to different steel types, the composite mechanical properties range from 700 MPa to 1800 MPa in strength.
The production structure section of Peak Kong Special Steel is:

Outer diameter size 100mm-500mm. Wall thickness 5mm-10mm. Brand: S355.S460.S690

Application fields of composite hollow structural profiles
  • 1. Construction field: widely used in high-rise buildings, bridges, tunnels and other building structures as supports and connectors.
  • 2. Transportation field: New steel profiles are used to manufacture structural parts and force transmission parts for subways, high-speed rails, automobiles and other transportation vehicles.
  • 3. Offshore energy: New steel profiles are used to manufacture various mechanical equipment and parts/hoisting equipment, offshore platforms, wind power generation, breeding, etc.
  • 4. Ship field: widely used in LNG ships and bulk carriers, engineering ships and salvage ships, decks, cabins and masts.
  • 5. Engineering machinery: widely used in cranes, tower cranes, cable cars, and other jibs.
