Aluminum Supply Company, Inc. (ASCO) was founded by Robert Marshall in 1948. The original concept was to create a one-stop wholesale depot for aluminum building products and accessories. Detroit did not have a resource like this at the time, so there was a clear opportunity for success.

ASCO quickly became known as the Metro Detroit area's premier supplier of architectural building products. As market trends and demands have changed over time, ASCO has adapted and evolved, continually striving to offer diverse products and experienced support staff.

Aluminum Supply Company is dedicated to reaching out to the local community. We especially support programs and charities that educate and motivate the children of Metro Detroit.
