Extension Springs
We’re a Force In Mechanical Extension Spring Manufacturing
Extension springs resist pulling forces, storing energy as they stretch and returning to their original length when the force is released.
Iowa Spring manufactures extension springs of all sizes, including large wire diameter and high initial tension springs. We are ISO 9001:2015 certified and have scale testing equipment to measure spring rate, initial tension and loads requirements for every spring.
These springs play a critical role in industries such as agricultural equipment, material handling, oil and gas, and snowplow to name a few. When you need dependable tension control and long-lasting durability, Iowa Spring delivers custom extension springs built for your application.
