12 Inches Door Spring
Engineered for reliability and strength, this 12-inch industrial door spring provides consistent tension for heavy-duty commercial doors, gates, and access panels. Manufactured from high-tensile spring steel, it offers excellent fatigue resistance and a long service life, making it ideal for MRO and new fabrication projects.
- High-Tensile Spring Steel
- 12-Inch Overall Length
- Corrosion-Resistant Finish
- Application: Industrial & Commercial Doors
This industrial-grade door spring is manufactured from high-carbon spring steel wire, conforming to standards such as ASTM A227/A228 for consistent quality and performance. The steel is coiled and heat-treated to achieve optimal temper, providing superior elasticity and resistance to deformation under repeated stress cycles. This robust construction ensures the spring maintains its tensile strength and retraction force over thousands of uses, preventing premature failure and ensuring operational safety in demanding industrial environments. The zinc-plated finish provides a critical layer of corrosion protection against moisture and environmental contaminants.
Our 12-inch door springs are a critical component for both maintenance, repair, and operations (MRO) and new fabrication. They are commonly used to provide tension or counter-balance for roll-up warehouse doors, heavy-duty access hatches, industrial gates, and machinery guards. Fabricators in the Los Angeles area rely on these springs for custom door and gate assemblies, while maintenance crews use them as direct replacements to restore functionality and safety to existing equipment. Their durability makes them a dependable choice for high-traffic commercial and industrial applications.

Target Users
This product is ideal for maintenance technicians, facilities managers, welders, and metal fabricators who require a durable and reliable spring for commercial or industrial-grade hardware applications. It is a go-to component for anyone building or repairing heavy-duty door and gate systems.
Finish Options
Our standard 12-inch door springs come with a durable zinc-plated finish. This coating provides excellent corrosion resistance suitable for most indoor and many outdoor environments, protecting the underlying steel from rust and extending the product's service life.
How to Measure
To ensure you order the correct replacement spring, measure the following: 1) Overall Length: From the outside of one end hook to the outside of the other. 2) Outside Diameter (OD): The full width of the coil body. 3) Wire Diameter: The thickness of the spring wire itself, best measured with calipers.
Example: 12" OAL x 1.5" OD x 0.125" Wire Diameter Door Spring
