Garage door springs are a vital component of your door system and are constantly used whenever the door is opened or closed. Unfortunately, wear and tear will break down the springs over time, making them unfunctional. Once the springs break down, it becomes more challenging to open and close the door safely. Therefore, choosing the suitable one is essential when it is time for a garage door replacement

The Door and Access Systems Manufacturers Association (DASMA), a leading garage door organization, developed the Garage Door Springs Color Coding System to aid in proper identification for repair, ordering, and warehousing purposes. Springs with color coding schemes can be found on most garage doors. The colors correspond with the different sizes and weights of the springs. This blog will teach you more about garage door spring color coding.

Types of Garage Door Springs

Torsion Spring

The torsion spring is a vital component of the garage door, assisting with the opening and closing the heavy door. The spring is attached to a horizontal bar above the door and twists and tightens as the door closes. When the door is opened, the spring unwinds and helps lift the door’s weight—making it possible to open a heavy garage door with relative ease.

Extension Spring

Tension springs are the more commonly used and less expensive type of spring for garage doors. They are attached on both sides of the door tracks and linked to cables running to the bottom brackets on each side. These cables then go through a series of pulleys to reach the springs. As a result, tension springs expand and contract as the door is opened and closed, rather than twisting.

Color Coding on Extension Springs

The colors of extension springs indicate the amount of door weight they can lift. Two springs of the same color can raise the same amount of weight. There are ten colors, so the colors repeat for springs designed for lighter or heavier doors.

Color Code Chart for Garage Door Torsion Springs

Torsion springs are often color-coded to indicate the wind’s direction and the wire gauge. It can be helpful when determining how best to use the spring. For example, if your garage door springs have red cones, they should be installed on the left side. Right-wound springs are designed to be installed this way. Springs with black cones are left-wound and should be installed on the right side of the garage door. 

The torsion spring is color-coded so technicians can quickly determine the wire’s thickness or gauge without measuring it. In addition, color coding allows the technician for quick and accurate repairs or replacements. Remember that the wire gauge colors are different for each type of spring.

The Wire Gauge Colors are as Follows:

Color                            Inches                                            Millimeters

Orange                .120/.192/.273/.363/.485                    3.00/4.20/6.25/8.00/11.10

Light Blue            .125/.200/.283/.375/.4900                  xx/4.50/6.40/8.10/11.50

Yellow                  .135/.207/.289/.394/.500                   3.20/4.60/6.50/8.40/11.70

White                   .139/.218/.295/.406/.531                   xx/4.70/6.80/8.80/12.00

Red                      .143/.225/.297/.422/.563                  3.40/4.80/7.00/9.20/12.30

Brown                  .148/.234/.307/.431/.625                   xx/5.00/7.30/9.60/13.00

Tan                       .156/.238/.313/.438                          3.50/5.25/7.35/10.00

Green                   .162/.244/.319/.453                         3.60/5.50/7.50/10.50

Gold                     .177/.250/.331/.462                          xx/5.75/7.60/10.70

Purple                  .182/.257/.594                                  3.80/6.00/12.50

Torsion springs have a line running across them that helps technicians determine the spring’s tension. This line will distort as the spring is “charged,” giving the technician a reading of how tight the spring is wound.

The color coding system is designed to help identify the correct garage door springs for repair or replacement. It does not affect how you use or experience your garage door and is not something you need to know about. DASMA devised the system to aid companies performing garage door repair services. Though it may seem cryptic, it serves an essential purpose.
