Fit adjusted in place
On site welding is useful when existing steel is out of square, fixed in place, or too large to move. Field fit-up solves conditions the shop cannot fully predict.

Why The Grate Guys
What to expect from on site welding in Sarnia
Joint access confirmed
Welding needs space for the welder, leads, shielding, and cleanup. Crowded corners, overhead joints, and active equipment areas are planned before arrival.
Surroundings protected
Finished floors, wall panels, glass, and nearby equipment need protection from sparks and heat. Site welding is planned around what cannot be moved.
Coating repair included
Welded areas often need grinding, primer, paint, or galvanizing touch-up afterward. The repair is not complete if exposed steel is left to rust.
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 on site welding 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 On Site Welding
On Site Welding 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 on site welding 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.

On Site Welding in Sarnia: how a job gets scoped
Sarnia on site welding typically centres on site access, regional shipping, building use, exposure, measurement tolerance, and install timing.
