Product Overview

A welded CHS steel tube column is a heavy fabricated steel structure pillar made from thick-wall circular hollow section tube. Corbels, brackets, connection plates, and flange plates are welded in the factory to carry loads from upper steel beams and transfer them to the foundation.

Because the column is fabricated rather than rolled, the diameter, wall thickness, corbel position, and bolt pattern all follow your structural drawing. Site work is limited to simple bolted assembly.

Key Advantages

• Omnidirectional Strength: Load is carried evenly in every direction, simplifying multi-directional beam connections.

• Aerodynamic: Lower wind drag than open sections, which is ideal for exposed and high-rise projects.

• Clean Aesthetics: Smooth round appearance perfect for exposed columns in public and commercial buildings.

• Reduced Site Work: Corbels, brackets, and base plates are welded in the factory, drastically reducing site welding.

• Custom Sizing: Diameter and wall thickness are set by the drawing, not limited to a fixed catalogue.

• Certified Quality: Welding is inspected before surface treatment, with reports issued with the shipment.

• Logistics Friendly: Bolted splices make the transport and erection of long columns practical.

Material & Surface Options

Material Standards:

• China: Q355B to GB/T 1591

• American: ASTM A500 Grade C

• European: EN 10219 S355J2H

• Australia/NZ: AS/NZS 1163 C350L0 (for the tube) + AS/NZS 3678 Grade 350 plate (for welded flanges and base plates)

Surface Protection:

• Shot blasting to the required surface preparation grade.

• Shop primer for transport protection.

• Multi-coat paint system in the specified color.

• Hot-dip galvanizing for outdoor and coastal service.

• Duplex system (galvanizing + topcoat) for long service life.

Fabrication and Inspection

• CNC Cutting: Precision cutting of tubes, plates, and connection parts.

• Qualified Welding: Welding of corbels, brackets, stiffener rings, and end plates under qualified procedures.

• Weld Inspection: Visual, ultrasonic (UT), or magnetic particle (MT) testing.

• Precision Drilling: Machined drilling of bolt holes with position check before packing.

• Dimensional Check: Straightness, ovality, and length verified before surface treatment.

• Documentation: Mill Test Certificate (MTC), weld inspection report, and dimensional report issued with every shipment.

Typical Applications

• Load-bearing columns in industrial workshops and plant buildings.

• High-rise and multi-storey steel frame columns.

• Pipe racks and utility corridors in process plants.

• Steel bridge piers and heavy support members.

• Equipment frames, skids, and support towers.

• Long-span structures where round columns give a clean elevation.
