When choosing a new steel garage door, it can be difficult to understand what the importance is or what gauge of steel door is best suited to your garage. The gauge is the thickness of the steel door, so some people may feel that want a higher steel gauge, as they feel that it will offer them greater security but there are other factors that help determine garage door security. You need to also consider locking mechanisms and the type of operation of the door.

When going for a heavier gauge steel door, you also need to bear in mind that this affects the ease of installation and will require load bearing walls, in order to safely secure a heavier door. The thickness or gauge of steel doors, often ranges between 1.4mm and 2.0mm. When a garage is detached from a residence, it is not necessary for it to be insulated but if it is attached to the home, having an insulated garage door is recommended to save on energy costs.

When choosing the gauge of your steel garage door, you will want to factor in whether or not it will need to be insulated or not, which will add to the weight of the door, which could then affect its operation, especially if it is electronic.
