Structural Steel Fabrication

The manufacture of steel components — columns, beams, frames, and connections — designed to carry load in buildings, bridges, and industrial structures.

What is Structural Steel Fabrication?

Structural steel fabrication involves cutting, drilling, notching, welding, and finishing structural steel sections — I-beams, HSS (hollow structural sections), channels, angles, and plates — to produce load-bearing components for construction and industrial applications. The process requires adherence to structural codes (CSA S16, AISC, CWB W47.1) and detailed engineering shop drawings. ATS Metal Fabrication provides CWB W47.1 certified structural welding with full traceability documentation, CNC tube laser cutting for precise tube connections, and in-house engineering support for steel fabrication packages.

Frequently Asked Questions

What structural welding certification does ATS hold?
ATS Metal Fabrication is certified to CWB Standard W47.1, Division 2 — covering fusion welding of steel for structural applications. This certification is required for structural building steel and is supported by our ISO 9001:2015 quality management system.
Can ATS fabricate from structural engineering drawings?
Yes. We work directly from engineer-stamped structural drawings, including connection details and weld symbols. Our engineering team reviews all drawings for fabrication feasibility and provides DFM feedback before production begins.
What is the maximum steel section size you can process?
ATS Metal Fabrication handles standard structural sections up to heavy column and beam sizes. Contact us with your specific section sizes, lengths, and connection requirements for a capacity confirmation.
