Welded CHS Steel Tube Column Circular Hollow Section Bracket Heavy Fabricated Steel Structure Pillar

Welded CHS Steel Tube Column Circular Hollow Section Bracket Heavy Fabricated Steel Structure Pillar

A welded CHS steel tube column is a heavy fabricated steel structure pillar made from thick wall circular hollow section tube, with corbels, brackets, connection plates and flange plates welded in the factory. It carries the loads from upper steel beams and transfers 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 bolted assembly.

Advantages

• Load is carried evenly in every direction, so multi direction beam connections are simpler
• Lower wind drag than an open section, which helps in exposed and high rise projects
• Clean round appearance for exposed columns in public and commercial buildings
• Corbels, brackets and base plates welded in the factory, reducing site welding
• Diameter and wall thickness set by the drawing, not limited to a fixed catalogue
• Welding inspected before surface treatment, with reports issued with the shipment
• Bolted splice makes transport and erection of long columns practical

Material Options

• Q355B to GB/T 1591
• ASTM A500 Grade C
• EN 10219 S355J2H
• AS/NZS 1163 C350L0 for the tube, with 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 colour
• Hot dip galvanizing for outdoor and coastal service
• Duplex system of galvanizing plus top coat for long service life

Fabrication and Inspection

• CNC cutting of tube, plates and connection parts
• Qualified welding of corbels, brackets, stiffener rings and end plates
• Weld inspection by visual, ultrasonic or magnetic particle testing
• Machined drilling of bolt holes and position check before packing
• Straightness, ovality and length verified before surface treatment
• Mill test certificate, weld inspection report and dimensional report issued

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

Questions Buyers Ask

Tube column or H section column?
A round tube column suits multi direction connections, exposed elevations and windy sites. An H section column is often more economical for simple orthogonal frames.

Which standard applies to the tube?
AS/NZS 1163 C350L0, ASTM A500 Grade C or EN 10219 S355J2H. AS/NZS 3678 applies to the plate used for flanges and base plates.

Can corbels and plates be welded before shipment?
Yes. All welded details are completed and inspected in the factory, so site work is bolted connections only.
