Application
Garage door springs are the core of the lifting system, balancing the door's weight mainly through torsion springs (for most overhead doors) or extension springs.
They also provide buffering for safety. Specifications should be customized according to the door's weight. Rust-proof and UV-resistant treatments are needed in humid or
outdoor environments. Regular inspection and lubrication are required, and replace them every 5-8 years to prevent aging.
