Garage door struts stiffen door sections to prevent them from bending or breaking. Doors over 10 feet wide usually have at least one strut across the top of the top section. Howdy: My 3 car attached garage (pretty much only used as a workshop, I don’t bring vehicles in except to work on them) has a 16’W x 7’H garage door a. Looking for suggestions on 9′ vs 10′ wide for the ‘main’ door, and whether anyone has a 10′ door and wishes they had used a 9′ instead. 10s would leave skinny walls between doors, and since the building could not be that 3 feet longer, it wouldn’t look correct. Did you know that most garage spaces are a minimum of 10 feet wide? While many people traditionally think that garages are only for car storage, the truth is that garages are capable of so much more.
Most new garage doors are made of steel backed by rigid-foam insulation. Warranties for steel doors start at 10 years; limited lifetime coverage is not uncommon.
