Customization:
Our garage door torsion and extension springs are engineered for durability and precision, featuring high-strength materials and customizable designs to suit diverse garage door systems. Built with corrosion-resistant galvanized steel, these springs ensure long-term reliability while maintaining optimal torque and safety.
| Feature | Specification | Application Scenario |
|---|---|---|
| Material | Carbon steel, high carbon steel | Heavy-duty garage doors requiring high tensile strength |
| Surface Treatment | Galvanized | Corrosion protection in outdoor environments |
| Load Type | Extension, Torsion | Balancing vertical/lateral door weight distribution |
| Wire Diameter | 0.03mm–20mm | Customizable for door sizes (e.g., 8–12mm for standard residential doors) |
| Safety Features | End caps, safety washers | Preventing spring slippage and enhancing user safety |
| Color Coding | Standardized color labels | Quick identification of tension/load capacity during installation |
Adjust wire diameter (0.03mm–20mm) to match door weight and size requirements. Choose between extension or torsion designs based on your door mechanism. For extreme durability, opt for high carbon steel in high-traffic commercial applications.
Whether reinforcing a residential garage door or upgrading a commercial system, our springs provide tailored solutions. Their galvanized finish and precise engineering ensure seamless operation while minimizing maintenance needs.
