Why The Grate Guys
What to expect from door security grilles in Markham
Anchors hit solid backing
Grilles mounted to hollow frames, block, wood, or steel need different fasteners and backing. Security depends on the anchor, not just the bars.
Locks reachable by staff
Lock location, removable panels, and inside or outside operation are planned around the staff closing procedure. A hard-to-use grille is the one people stop locking.
Bars resist pry points
Bar spacing, perimeter frame depth, and welded intersections are selected to limit prying at the latch side and bottom edge. Those are the spots that get attacked first.
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
Your door security grilles is supported by Canadian-made fabrication, Canadian steel, clear local coordination, and a shop team close enough to solve site details before they become delays.
