Expert Steel Fabrication & Erection in Markham
Steelworks Inc. is proud to serve the expanding commercial and industrial sectors of Markham, Ontario. Though we are not physically based in Markham, our team regularly delivers reliable structural fabrication and erection services across the region. From downtown developments to suburban industrial builds, we bring the technical know-how, capacity, and commitment needed to get the job done right.
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.
