Springs, Compression Springs, Flat Springs and Tension Springs
you are looking for a British spring maker, look no further than
Leeming & Peel, makers of spring coils and wire springs for
extension springs for uses such as garage door springs
as well as carburetors and trampolines.
Tension springs are coiled tightly to resist stretching
or tensile force. Pull it outwards and the spring will
attempt to re-coil. As the spring is further extended
the resistance increases. Compression springs work in
the opposite way.
