Custom Extension Springs

Stalder Spring is an industry leader in the engineering and manufacturing of custom extension springs, such as carbon steel or stainless steel extension springs. These kinds of springs are designed specially to absorb and store energy as well as resist a pulling force.

The initial tension dictates how firmly an extension spring is coiled. Specific requirements for applications can be reached by tweaking this tension.

Due to their particular characteristics, extension springs are used in a number of these industries, including:

  • Agriculture 
  • Manufacturing 
  • Construction 
  • Petrochemical
