How Are Garage Door Springs Tested?

Many customers often ask: How do you test garage door springs? The quality of the spring directly determines the safety and lifespan of the garage door. Here’s a simple breakdown of the common testing process in our factory.

1. Material Inspection

Before production, we check the steel wire to ensure it meets ASTM A229 standards. This includes:

• Measuring wire diameter accurately

• Checking hardness and tensile strength

• Inspecting the surface for cracks or defects

2. Dimension Check

After production, each torsion or extension spring is measured for inner diameter, wire diameter, and length, ensuring it matches the customer’s specifications.

3. Torque Testing

The key feature of a torsion spring is its torque. We install the spring on testing equipment to simulate door opening and closing, verifying if it provides the correct balance.

4. Cycle Life Testing

This is the most critical step. Springs are placed on a cycle test machine, where they are compressed and released repeatedly to simulate daily usage. The standard lifespan is 15,000–17,000 cycles, ensuring long-term durability.

5. Surface Treatment Testing

For springs with electrophoresis coating or galvanization, we test rust and corrosion resistance to make sure they perform well even in humid, cold, or snowy environments.

Conclusion

Testing garage door springs is not just about numbers – it’s about ensuring safety, stability, and durability. With strict inspection at every stage, we guarantee that every spring we deliver is reliable, long-lasting, and trustworthy.
