Why The Grate Guys
What to expect from metal doors in Oshawa
Lower panels protected
Commercial metal doors get hit by carts, boots, pallets, and water at the bottom edge. Kick plates, sweeps, and reinforced lower rails are selected around that abuse.
Hardware preps coordinated
Closers, panic hardware, locks, hinges, viewers, and plates need the right reinforcement inside the door. Late field drilling weakens the assembly.
Finish follows exposure
Interior service doors, exterior doors, wet rooms, and back-lane doors need different coatings or galvanized options. Rust usually starts at edges and hardware cuts.
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 metal doors with Canadian-made fabrication, Canadian steel, clear local coordination, and a shop team close enough to solve site details before they become delays.
