Dependable Fabrication and Erection Support for Thunder Bay Projects

Thunder Bay is a powerhouse of industrial and commercial activity in Northwestern Ontario, home to major infrastructure developments, resource operations, and institutional builds. Whether it’s structural steel for a new facility, mobile welding for maintenance, or custom fabrication support, Steelworks Inc. brings decades of experience to the job—right when you need it.

We specialize in structural fabrication, erection, crane construction, welding, and surface prep services to support Thunder Bay’s contractors, project managers, and industrial teams.

Our Services

At Steelworks, we specialize in industrial-strength solutions built to last. From structural fabrication and crane construction to expert welding and protective blast and paint finishes, our services are tailored for demanding environments and complex builds. Every project is backed by decades of experience, certified tradespeople, and a commitment to doing the job right the first time.

Custom Fabrication

No cookie-cutter parts here. We custom-fabricate steel components for your project based on engineered drawings or site requirements. Need beams, frames, or complex assemblies? We’ve got you covered.

Steel Erecting

Our erecting crews have experience with commercial, industrial, and civic builds. Whether it’s a 5-ton canopy or a 600-ton facility, we raise steel safely and efficiently—often working alongside your general contractor or project lead.

Welding Services

Our welding department handles structural, pressure, and specialty welds with precision and speed. We support both in-shop fabrication and on-site welding for installations and repairs.

Crane Construction

We also provide structural work related to overhead cranes and hoisting systems—designing and installing support frames, runway systems, and load-bearing steel components.
