BHI produces a wide variety of Extension Springs

  • .004” to .312” diameter wire sizes.

Extension springs are manufactured from a wide variety of materials including music wire, hard drawn, oil tempered, galvanized wire, stainless steels and copper alloys, as well as exotics such as pre plated materials (gold, silver, tin) inconel, chrome vanadium and many others.


State of the art CNC Wireforming capability as well as conventional coiling machines.

An extension spring is the opposite of a compression spring, as push now becomes pull. Like compression springs they come in a variety of shapes and sizes. One of the most critical factors with these extension springs is the design of the hook. If done incorrectly, this can result in failure.

At BHI we use special computer extension spring design software on every application to ensure proper spring life and design correctness.
