China OEM Garage Door Window Frame - 3m Galvanized Garage Door Spring – Bestar Detail:
Whereas oil-tempered torsion springs are heated and quenched in oil, zinc-galvanized springs are subjected to the hot-dip galvanization process. This process involves immersing the steel spring in a vat of molten zinc at extremely high temperatures. Many people choose zinc-galvanized torsion springs because of their incredible resistance to rust and corrosion.
We offer a wide selection of zinc-galvanized torsion springs in 1.75” and 2” diameters in multiple wire sizes ranging from 0.192, 0.207, 0.218, 0.225, 0.234, 0.243, 0.250, 0.262 to 0.272.
