Our Simply Elegant Metallic canvas and BC Metallic Canvas are pretty close to each other with a 2 over 1 weave where Hahnemuhle's is a 1 over 1 weave. They are all pretty similar in production though.
The coating does give it a metallic look like the metallic papers available. Hahnemuhle actually doesn't make it themselves and gets it from the same places all of us get it from. It can be altered per the brand (Hahnemuhle, IT Supplies, BC, Inkpress, etc) that sells it.
