Manufacturing Facilities

Spring steel refers to high carbon or alloy steel used in the manufacture of springs. The steel is heat-treated to develop specific properties, making it ideal for applications requiring the ability to return to its original shape. Our Spring steel flats are produced using advanced technology for precisely controlled thickness.
