The Metal Construction Association (MCA) has released a white paper focused on Metal Composite Material (MCM) labeling. The document, Labeling: Who Cares and Why, addresses the need to make sure the MCM product or system has been tested by an approved agency and labeled according to IBC code. MCM is formed by joining two thin skins of metal—typically aluminum but sometimes zinc, copper, stainless steel, or titanium—to a polyethylene or fire-retardant core and then bonded under a precise temperature, pressure, and tension.
This makes MCM lighter and more versatile and flexible than a solid metal of similar thickness—qualities that have helped transform modern architecture, according to a MCA news release. “Anyone searching the internet can find dozens of products claiming to be MCM,” says Karl Hielscher, MCA's Executive Director. “MCM is used in many applications requiring different performance capabilities. Clear, consistent labeling is important to help assure the right materials are chosen and used to meet design requirements.”
