China wholesale Insulated Double Garage Door - 120″ 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 Galvanized Garage Door 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, with max length 120″.
