Strength and Durability

Structural steel pipes have a high load-bearing capacity, making them suitable for applications that require strong structural support. They can withstand heavy loads, pressure, and external forces without deformation or failure.


Structural steel pipes are highly versatile. They come in various sizes, shapes, and grades, allowing for flexibility in design and construction. They can be easily fabricated, cut, welded, and shaped to meet specific project requirements.

Fire Resistance

Structural steel pipes maintain the property of fire-resistant. They do not contribute to the spread or intensification of fires. In the event of a fire or other disaster, steel pipes maintain structural integrity longer.

Corrosion Resistance

Structural steel pipes are often coated with protective layersto enhance their resistance to corrosion. The protective coating helps to prolong the lifespan of the pipes and reduces the need for maintenance.

  • Construction: Frameworks, columns, beams, and trusses.
  • Infrastructure: Bridges, tunnels, and pipelines.
  • Industrial: Machinery frames, support structures, and storage tanks.
  • Transportation: Vehicle frames, railway components, and marine structures.
