Flat sheet aluminum is the most common substrate for long-to-permanent use signs and is our #1 substrate. Our aluminum blanks are manufactured at our local production facilities. Our standard signs are manufactured with radius corners, 7/16" holes for mounting and comply with the Transportation Association of Canada (TAC).
Our aluminum is 50% thicker than many of our competitors. We use a heavy gauge sign grade aluminum alloy that is long lasting and rust free, even in harsh weather. The ASTM 5052-H38 sign grade aluminum alloy standard is .081" (2mm). Our aluminum is cleaned and degreased, and edges are cropped to prevent injury.
