Perforated Aluminum Sheeting In Missouri Where In Canada BC Can I Buy Aluminum Sheet Metal?

Where in Canada BC can i buy aluminum sheet metal? - perforated aluminum sheeting in missouri

Aluminum sheet 1 mm thick. the 2 meter or square sheets of 4 feet square to be. I also need the same thickness of aluminum that has these small holes evenly around (I think its called perforated), probably the holes of 0.2 mm in diameter. Online orders may be an option as well, but if I prefer to order online all from one site.
