A garage door is a large door on a garage that can either be opened manually or by a garage door opener. Although of many designs, most garage doors are sectional, upward-acting, and self-storing. Garage doors are necessarily large to allow passage of vehicles.
Garage doors can be made out of many materials, but steel is the most popular. A common material, formed steel sheets are embossed to look like a raised panel wooden door. A design mimicking carriage house doors has also become quite popular since about 2002. A more economical alternative for garage doors is steel stamped construction.
First United Door Technologies, based in Tempe, Arizona produces garage doors made of steel and wood.
Garage doors… they’re all about curb appeal and diversity in design.
