Industrial mezzanines & steel stairs in Toronto.
Span Line is a Toronto steel fabricator — our shop is in Etobicoke's Islington–City Centre West industrial area. We engineer, build, and install structural mezzanines, work platforms, and code-compliant stairs for warehouses and plants right across the city.
In short: We're a Toronto-based structural steel fabricator building industrial mezzanines, platforms, and stairs. Because the shop is in the west end, work in Etobicoke, North York, Scarborough, Downsview, and the Port Lands is a short drive — measures and installs happen on your schedule, stamped to OBC 2024 and welded to CWB W47.1.

Right in the city's industrial grain.
Toronto's industrial floor space is spread across a handful of dense pockets — Etobicoke around the 427 and the airport lands, North York and Downsview, the Scarborough employment districts off the 401, and the reindustrialising Port Lands. Most of it is older stock: tight columns, low-ish clear heights, and slabs poured for a different era of use. That's exactly the ground a mezzanine has to work with, and it's the ground we know.
Being based in Etobicoke means we're not scheduling a Toronto site visit as a half-day expedition — it's a short drive. That shows up in faster measures, tighter install coordination, and a crew that can be back the next morning if a site condition changes. For buildings landlocked by the city with no room to expand out, the only direction left is up.
Steel that solves a floor problem.

Measure, stamp, build, install.
-
01
Site measure
A ~30-minute visit to capture real column centres, clear heights, and slab condition. Being in-city, we schedule Toronto measures quickly — often within a couple of business days.
-
02
Stamped drawings
Engineered and P.Eng.-stamped to OBC 2024 in-house — the set the Toronto Building needs for the permit.
-
03
In-house fabrication
Cut, welded, and finished at our shop to CWB W47.1 — not white-labelled out. Galvanizing or shop primer as the environment calls for.
-
04
Install on your window
Sequenced to land on a shutdown or off-shift window and installed by our own crew — including the tight-access downtown and older-building conditions the city is full of.

Span Line Systems is the industrial mezzanine and stair division of Art Metal Canada. Drawings are stamped by a PEO-licensed P.Eng. on staff; welding is done to CWB W47.1 and CSA W59 by our own certified fabricators. We don't white-label the fabrication or subcontract it out — the shop that draws it builds it.
