Custom Steel Pipe Columns and Tubular Structures Fabrication to AS/NZS Standards

Tubular steel structures are not just plates and sections cut and welded together. They involve rolled plate, longitudinal seams, circumferential joints, and precise end preparations — and for Australian projects, every one of those steps must be traceable to AS/NZS standards.

We fabricate pipe columns and tubular structures to your drawings, covering the full AS/NZS chain.

What We Fabricate

Standards Compliance Matrix

Manufacturing Focus: Tubular Steel

Tubular structures demand tighter control than flat-plate fabrication. Our process focuses on four critical points:

1. Cutting & End Preparation

• Precision cutting and beveling for pipe ends and connection profiles

• End preparation controlled for proper weld penetration and fit-up

2. Rolling & Forming

• Plate rolled to specified diameter with controlled roundness

• Longitudinal seams prepared and aligned for welding

3. Welding & Distortion Control

• Longitudinal and circumferential welds performed to AS/NZS 1554 qualified procedures

• Welding sequence planned to control distortion and straightness

4. Dimensional & Visual Inspection

• Pipe diameter, wall thickness and length verified against drawings

• Straightness, end squareness and hole positions checked

• Weld visual inspection and NDT as specified

​

Quality Assurance & Traceability

Every project follows a documented quality system aligned with AS/NZS 5131:

• Construction Category (CC) assessment — CC2 or CC3 as specified by the project

• ITP (Inspection and Test Plan) prepared for each project

• Traceability — material certificates, process records, welding records and NDT records maintained throughout fabrication

• Surface treatment and corrosion protection applied per project requirements

• Geometrical tolerances controlled per project specification

Note: AS/NZS 5131 certification covers different Construction Categories. We can discuss the CC level appropriate to your project and confirm the scope of coverage.

Documentation Package

Each shipment includes:

• Material Test Certificates — traceable to heat number and project mark

• WPS/PQR — AS/NZS 1554 qualified welding procedure specifications

• Welder Certificates — AS/NZS 2980 or ISO 9606.1 qualified

• Welding Coordination Records — per AS/NZS ISO 3834

• ITP Records — inspection and test plan sign-offs

• NDT Reports — visual, MT, PT, UT or RT inspection as specified

• Dimensional Inspection Records — diameter, length, straightness and hole position verification

• Surface Treatment Records — coating and corrosion protection documentation

• As-built Shop Drawings — with component marks and erection sequence

• Packing List — weights, dimensions and drawing references
