Architectural Canopies and Standing Seam Metal Awnings Many Architects are choosing Metal Awnings for their commercial projects. Although they are initially more expensive, their durability and functionality provide long term value. Unlike traditional awnings, Architectural Metal overhangs require only 9-12” of space and are ideal over doorways. They are hung using overhead hangers, and can hold heavy snow and keep rain from the entryway.  Standing Seam Metal awnings are traditional awnings with a more durable cover.  More than 30 colors are available, and a 20 year warranty, 10 years than canvas awnings.
