Engineered mezzanines & industrial steel stairs. Built for the floor load.
Mezzanines, stair towers, and guardrail systems — engineered at our Etobicoke shop, welded under CSA W59, installed on your shutdown window. We walk the floor, take real column measurements, and return a stamped price inside a week.
Two lines of work: mezzanines for more deck area, and stairs (towers, crossovers, ladders) for code-compliant access. Engineering is stamped in-house by our P.Eng.; welding is tracked per-weld on CWB W47.1 traceability sheets. Nothing critical gets subcontracted.

Industrial mezzanines
Structural steel mezzanines engineered for storage, work platforms, or equipment support. Custom spans up to 40 feet; load ratings to 250+ psf.
Heavy-duty industrial steel stair systems: egress, fire escape, outdoor stair towers, straight-run, switchback, crossovers, and ship's ladders. Designed to OBC 2024 / IBC with slip-resistant treads and code-compliant guardrails.
Span Line is the part of Art Metal that only does mezzanines and stairs. That means the people drawing your deck have done this exact thing hundreds of times, the welder assigned knows this joint, and the install crew shows up with the right rigging on the right day.
