Whatever the size, we'll get the spring you need. Send us a description, drawing, or sample of the extension spring you require.

Zinc-plated springs have mild corrosion resistance.

Stainless steel springs have good corrosion resistance. They’re generally easier to extend than steel springs.

Passivated stainless steel springs are more corrosion resistant than unfinished stainless steel springs.
