Large Diameter Heavy Wall Rectangular Steel Tube for Structural Applications
Product Introduction
Large Diameter Heavy Wall Rectangular Steel Tube
Fuyuansheng large diameter heavy wall rectangular steel tubes are designed for structural projects that require high load-bearing capacity, dimensional stability and reliable performance under demanding conditions.
Manufactured using controlled forming and welding processes, the rectangular hollow section provides a closed structural profile with good resistance to compression, bending and torsional forces. Compared with conventional open steel profiles, its enclosed cross-section can provide efficient structural performance while maintaining relatively simple fabrication and connection.
The tubes are available in a wide range of steel grades, dimensions, wall thicknesses, lengths and surface treatments. Custom specifications can also be produced according to project drawings, structural requirements and applicable international standards.
This makes the rectangular steel tube suitable for large-span buildings, bridges, industrial structures, transportation infrastructure, cranes and heavy machinery.

Why Choose Large Diameter Heavy Wall Rectangular Steel Tube?
Designed for demanding structural applications
Heavy wall rectangular steel tubes are particularly suitable when a project requires higher structural strength and stability than standard light-wall hollow sections.
Stable dimensional performance
Controlled manufacturing and inspection processes help maintain consistent dimensions and geometry, supporting accurate fabrication and assembly.
Suitable for large-scale structures
The combination of large cross-sectional dimensions and increased wall thickness makes these tubes suitable for heavy-duty structural frameworks and infrastructure.
Multiple surface treatment options
Black painting, shot blasting, epoxy coating and galvanizing can be selected according to environmental exposure and project requirements.
International standards available
Products can be manufactured according to standards including ASTM A500, EN 10210, EN 10219, JIS G3466 and GB/T 6728, depending on the required specification.
Advantage
Large diameter heavy wall rectangular steel tubes are widely used in large-span buildings, industrial facilities, bridges, infrastructure projects, equipment frames, cranes and other heavy-duty structural applications, where high strength, dimensional stability and reliable load-bearing performance are required.
