Lee Spring’s Heavy Duty Die Springs are not like an average spring, they’re made from different shaped wire than traditional springs for starters, and they work in slightly different ways. But different is not always a bad thing and these springs offer a number of benefits!
Heavy Duty Die Springs are manufactured using round wire instead of the traditional rectangular wire and they are specifically designed for heavy duty applications, making them up to 30% stronger than their rectangular wired cousins.
Die springs are powder coated and colour coded for ease of identification, ranging from the palest grey for light loads to a bold orange for extra heavy duties.
In a recent independent test conducted by the Institute of Spring Technology, Lee Spring's Heavy Duty Die Springs demonstrated a life-expectancy at least equal to traditional rectangular wire Die Springs, but they are up to 50% cheaper than the rectangle coil versions – now that’s a serious saving!
Heavy Duty Die Springs have very closely wired coils so they store more energy and reduce stress, they are shot peened to extend their life expectancy, and they are preset to prevent length loss in operations.
So it can pay to be unique with Lee Spring Heavy Duty Die Springs - they may be different but they’re strong, affordable and resilient to boot! Please contact us for more information.
