Commercial Roller Shutter Door Torsion Spring
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, thanks in large part to the hot-dip galvanization process. Free from the constant threat of rust formation, zinc-galvanized springs offer a longer lifespan than most oil-tempered springs.
