Contact SupplierHeavy duty metal compression spring is manufactured using round wire and designed to be used as a Die Spring or heavy duty coil spring in heavy stress, heavy load applications. Heavy duty compression springs are usually hot-coiled which allows use of thicker wire. Heating the material makes it more flexible and custom hot-coiled coil springs are usually preset which means they are wound to a length greater than the finished length, heat treated, then compressed solid one or more times to bring them to the specified length. The ends of a Heavy Duty Springs are closed and ground, providing adequate large bearing surface.
