Gym machines, trampolines, resistance trainers and outdoor fitness installations load springs directly with body weight. The failure mode is not a warranty claim but an injury, which puts the whole burden on wire quality, hook geometry and coating.
Hooks are formed as part of the coiling programme with a controlled transition radius, and the wire is hardened rather than simply bent to shape.
Black paint, galvanising and stainless options are specified for outdoor fitness equipment that stays exposed year round.
Springs supplied as matched sets are produced in the same run so a machine with four springs pulls evenly on all four corners.
Extension springs that pull a mechanism closed and hold it there
Formed hooks for hanging, tensioning and retail display
Torque delivered through an angle, not a stroke
Production photographs of parts from the families above.
The same seven step route applies to every industry we supply, with inspection built into it rather than added at the end.
Yes. Where a machine or a trampoline uses several identical springs, they are produced and packed as one run so the force matches across the set.
The working load, the travel and how often the spring cycles. Those three figures drive wire diameter, material and coil count.
Galvanised or stainless for the spring itself, with black paint where appearance matters as much as protection.
Tell us the position the spring sits in, the load it carries and the environment around it. That is enough to start.
