Choosing Signs That Survive Quebec Winters
Published July 2, 2026
A sign in Quebec faces conditions most of North America never sees: months of freeze-thaw, corrosive road salt spray, ice loading, and winter winds. The difference between a sign that looks new after ten years and one that fails in three is entirely in the materials and construction. Here is what to look for.
Structure: aluminum, not steel
The frame and returns should be aluminum — powder-coated or brushed — not mild steel. Aluminum does not rust, which matters enormously when a sign is sprayed with salt every winter. Fasteners should be stainless steel for the same reason. A sign built with the wrong metals will streak with rust stains within a couple of seasons.
Faces: weatherproof acrylic, sealed edges
Sign faces need to be impact-resistant acrylic or polycarbonate rated for outdoor use and cold. Cheap plastics turn brittle in deep cold and crack. Just as important are sealed edges and drainage — water that gets inside a cabinet and then freezes will expand and split a poorly sealed sign. Proper builds are weep-holed so any moisture drains out before it can freeze.
Illumination: cold-rated LED
LEDs actually like the cold — they run more efficiently at low temperatures — but the power supplies and wiring must be rated for it and sealed to at least IP65 against moisture. A sign lit at 3 a.m. in January should look exactly as bright and even as it does in July. That reliability comes from the module quality and the electrical protection, not luck.
What the warranty really tells you
A 5-year warranty on materials and workmanship is a signal that a sign is built for the climate — no manufacturer warranties a sign that will fail in Quebec winters. Every sign we build is engineered for freeze-thaw cycles, salt exposure, and high winds, and backed by that 5-year warranty. If a sign shop cannot stand behind its work for five Quebec winters, that tells you something.
