In a machined torsion spring, a pure couple can provide the moment. A pure couple can come from double tangs (external, internal and longitudinal), slots, splines (internal and external) and bolt circle configurations. One can also resolve the moment by an integral torque restraint on the coil side.
Stainless steel wall ties are used in a diverse range of applications. They are suitable for residential, commercial, and industrial construction projects. In particular, they are favored in environments where the risk of moisture exposure is high, such as swimming pools, warehouses, and coastal buildings. Their durability and resistance to harsh conditions make them an ideal choice for structures requiring long-lasting solutions.
