Garage door spring color chart
What does the color painted on your spring mean? The DASMA code marks torsion springs by wire size and extension springs by door weight. Look yours up, or read the full official chart.
Torsion colors mark the WIRE SIZE. Colors repeat, so confirm by measuring 10 and 20 coils.
What the color actually tells you
The paint is the DASMA color code (Technical Data Sheet #171), and it means two different things depending on the spring:
- Torsion springs — the color marks the wire size.
- Extension springs — the color marks the door weight the pair is rated to lift.
It's only partial identification. The color says nothing about inside diameter, length, or wind, and the colors repeat — so a color alone can never be the whole order.
Don't confuse it with the cone. A red winding cone means left-wound; black means right-wound. That's wind direction, not wire size.

60 lb (27 kg) | Brown |
70 lb (32 kg) | Orange |
80 lb (36 kg) | Gold |
90 lb (41 kg) | Light Blue |

Frequently asked questions
What do garage door spring colors mean?
The painted color is the DASMA code (Technical Data Sheet #171). On a TORSION spring the color marks the wire size; on an EXTENSION spring it marks the door weight the spring is rated to lift. It does not encode inside diameter, length, or wind direction.
What color is a .250 torsion spring?
Gold. But note the colors repeat across the DASMA range, so color alone never fully identifies a spring — always confirm the wire size by measuring 10 and 20 coils.
Do garage door spring colors repeat?
Yes. Torsion colors cycle through the range, and extension colors repeat every 100 lb. That is why the color is only partial identification and must be confirmed against a measurement or the door weight.
Is the winding-cone color the same as the spring color?
No, and confusing the two is a common mistake. The RED or BLACK winding cone tells you the wind direction (red = left-wound, black = right-wound). The DASMA color painted on the coils is the wire size. They are unrelated.
