Industrial mezzanines & steel stairs in St. Catharines.
Span Line builds and installs structural mezzanines, equipment platforms, and steel stairs for St. Catharines and the Niagara manufacturing base — the Eastchester and Merritton industrial areas along the QEW and Highway 406.
In short: We're an Ontario fabricator serving St. Catharines and Niagara with mezzanines, platforms, and stairs, stamped to OBC 2024 and welded to CWB W47.1. St. Catharines is about an hour down the QEW, within our install range, with shipping for supply-only orders.

For the QEW and the 406.
St. Catharines anchors Niagara's manufacturing — a powertrain and auto-parts base, metalworking and machine shops, and the agri-food and equipment operations of the wider Niagara belt, spread across Eastchester, Merritton, and Glendale along the QEW and Highway 406. It's a working industrial city where equipment platforms, catwalks, and access stairs are everyday requirements alongside storage decks.
Manufacturing floors reward steel built to a real spec — platforms sized to the equipment, welds to CWB standard, finishes suited to the environment. At about an hour down the QEW, St. Catharines sits within our install range, and modular bolt-together detailing keeps supply-only orders clean when a local crew handles the set.
Steel that solves a floor problem.

Measure, stamp, build, install.
-
01
Site measure
A ~30-minute visit to capture the equipment footprint or column grid, access, clear heights, and slab condition across Niagara's established industrial stock.
-
02
Stamped drawings
Engineered and P.Eng.-stamped to OBC 2024 in-house — the set the City of St. Catharines Building Services 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 or supply
On most St. Catharines projects we install with our own crew down the QEW; for supply-only orders we ship contractor-ready with erection drawings.
See the full engineering & install process for how each stage is controlled.
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.
