Why The Grate Guys
What to expect from dunnage steel in St. Catharines
Height clears services
Dunnage frames may need to lift equipment above roofing, piping, insulation, drains, or housekeeping pads. Clearance is built into the steel before installation.
Frames resist vibration
Mechanical equipment can shake a light frame loose over time. Bracing, plate thickness, and connection points are selected around vibration and operating weight.
Finish suits the location
Exterior roof dunnage, wet plant areas, and indoor storage supports need different coatings. Outdoor dunnage usually needs galvanizing or a coating system selected for standing moisture.
Made in Canada
Why Canadian-made metalwork matters
Custom metalwork made in Canada gives contractors, property teams, and facilities tighter quality control, faster lead times, and fewer cross-border delays. The work is fabricated in our Toronto shop, with Canadian steel and other metals selected when the application requires them.
Custom, local, built to spec
We support your dunnage steel with Canadian-made fabrication, Canadian steel, clear local coordination, and a shop team close enough to solve site details before they become delays.
Our Process
How we specify, fabricate, and deliver Dunnage Steel
Dunnage Steel is custom-fabricated or coordinated for commercial, industrial, municipal, institutional, retail, and construction sites, where fit, access, durability, and site conditions matter more than a stock product. The Grate Guys builds dunnage steel around drawings, measurements, traffic duty, finish exposure, and installation constraints using mild steel, structural steel, galvanized finish, powder-coat, stainless details, or aluminum where the site calls for it, made to order in our Toronto shop, licensed, insured, and WSIB-covered, with a workmanship warranty on every order, supplied and installed across the GTA and shipped Canada-wide.
- 01 Send your inquiry, drawings, photos, or a description of what you need.
- 02 We come measure and assess the St. Catharines site (or work from your specs and drawings).
- 03 We fabricate your dunnage steel to spec in our shop, finished for the conditions.
- 04 We return to deliver and install it, set, levelled, and done right on site.
