If you’re looking for springs to fit your garage door, you may have noticed that those springs are different colors. Garage door spring colors aren’t just decorative. They actually provide important information about the properties of that garage door springs and industry standards.  DASMA created an industry standard for color coding springs. To help you understand the garage door spring color chart, here’s what you need to know.

What Type of Garage Door Springs Are You Working With?

Before you can understand what the garage spring color code means, you need to know what kind of springs you are working with. Most garage doors use either torsion springs, which are compression springs that act on the door from above, or extension springs, which have the opposite action of torsion springs. They store energy when extended rather than when compressed, and they act on the door from the sides.

With extension springs, the color refers exclusively to the amount of door weight. Two extension springs are capable of lifting the amount of weight indicated by the color. There is a range of 10 colors, so the colors repeat for springs designed for lightweight doors or extra-heavy doors. The color chart works as follows:

Color Pounds Kilograms

Garage Door Torsion Spring DASMA Color Code Chart

Torsion springs work quite differently with respect to spring color code. These springs have two colors. First, each spring is either black or red. Black springs are “right wind springs” meaning you would install them on the left side of the top of the garage door. Red springs are “left wind springs” meaning you would install them on the right side. The other color signifies not the weight of the door it lifts, but the thickness, also called the gauge of the wire, as follows:

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