Structural Engineering, Stamped Drawings & Custom Frame Design
Steel Engineering & Design
Every steel building stands or fails on its engineering. We provide stamped structural drawings, custom frame design, and Ontario Building Code compliant packages — whether you're a contractor needing sealed plans for permit, an owner adapting a kit to your site, or a developer scoping a new build from scratch.

program.
The PEB-MS envelope adapts to occupancy. Switch program to see code-default loads, geometry windows, and material families. Final values are set during preliminary design — all subject to an Ontario PEng review.
