Product Overview

This circular steel pipe column is a heavy steel structure vertical member fabricated from thick-wall circular hollow section (CHS) tube. It is welded with corbels, connection plates, and flange plates to carry loads transferred from upper steel beams.

It is supplied as a factory-prefabricated column with end plates and splice details ready for bolted site assembly. Because the column is built rather than rolled, diameter, wall thickness, corbel position, and connection geometry all follow the project drawing instead of a fixed catalogue.

Structure and Build-Up

• Main Body: Thick-wall circular hollow section (CHS) steel tube, straight seam or seamless as specified.

• Corbels & Brackets: Welded to the tube for beam seating and shear transfer.

• Connection Details: Connection plates, gusset plates, and stiffener rings welded at beam and bracing interfaces.

• End Details: Flange plates or end plates at column base and splice locations.

• Foundation Interface: Anchor bolt template and matching base plate.

• Erection Aids: Lifting lugs and erection marking provided upon request.

Material Options (International Standards)

Corrosion Protection Options

• Surface Prep: Shot blasting to the required grade.

• Temporary Protection: Shop primer for transport and storage.

• Paint System: Multi-coat paint (intermediate and top coat in specified color).

• Hot-Dip Galvanizing (HDG): For outdoor, coastal, and high-humidity service.

• Duplex System: Galvanizing combined with a top coat for extended service life.

• Interior Protection: Applied to closed tube ends when required.

Fabrication and Inspection

• CNC Cutting: Tube, plate, and connection components cut to drawing dimensions.

• Qualified Welding: Corbels, brackets, flange plates, and splice plates welded under qualified procedures.

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

• Precision Drilling: Machined bolt holes to the connection pattern, with hole positions checked before packing.

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

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

​

Site Assembly

• Factory Prefabricated: Delivered with shop-welded corbels and connection details in place.

• Bolted Splices: Segment connections designed for site bolting without field welding.

• Foundation Match: Base plate and anchor bolt interface matched to the foundation drawing.

• Erection Ready: Match marking and member numbering aligned with the erection sequence.

• Smart Packing: Layout prepared so columns, beams, and bracing arrive in erection order.

Typical Applications

• Vertical load-bearing columns in industrial workshops and heavy plant buildings.

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

• Pipe racks and utility corridors in refinery and process plants.

• Steel bridge piers and heavy supporting members.

• Large equipment frames, skids, and support towers.

• Long-span structures where circular columns reduce wind load and provide a clean elevation.
