Why The Grate Guys
What to expect from window security grilles
Bars resist forced entry
Bar size, spacing, welds, and anchor depth are chosen around the risk at the opening. Thin decorative bars do not provide the same security.
Light remains usable
Grille pattern is planned so the window still provides light and visibility where needed. Security should not make the interior feel unnecessarily blocked.
Exterior finish protected
Rain, sill water, and condensation attack grilles at welds and anchors. Powder coat, galvanized steel, or stainless hardware are selected around exposure.
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 window 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.
