Venting planned before dipping
Hot dip galvanizing requires vent and drain holes in closed tubes, frames, and boxed sections. Those details must be added before the steel goes to the kettle.

Why The Grate Guys
What to expect from hot-dip galvanizing in St. Thomas
Best for exterior steel
Galvanizing is used on grates, frames, railings, guards, and outdoor steel exposed to salt, rain, and snow. It protects surfaces that paint may not survive well.
Threads and fits protected
Bolted assemblies, tapped holes, and tight slip fits need planning before galvanizing. Zinc build-up can change clearances if the part is not detailed correctly.
Cutting after avoided
Field cuts and late holes expose raw steel after galvanizing. We try to finalize notches, lifting points, and bolt holes before coating.
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 hot-dip galvanizing 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 Hot-Dip Galvanizing
Hot Dip Galvanizing 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 hot dip galvanizing 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. Thomas site (or work from your specs and drawings).
- 03 We fabricate your hot-dip galvanizing to spec in our shop, finished for the conditions.
- 04 We return to deliver and install it, set, levelled, and done right on site.
