Spring Steel refers to a group of a low alloy, medium carbon steel or high carbon steel with excellent yield strength. SMC is the leading manufacturing and supplier of spring steel products. We use high grade of raw materials to ensure premium quality and high tensile.

The high carbon spring steel strip is manufactured by continuous heat treatment furnace and oil quenching, can reach required hardness through annealling, tempering and hardended. Those strips are supplied with different options, such as cutting edge, round edge or dressed.  Surface includes matt finish (untreated), polished, bright, blue finish. With great mechanical properties, it can be easily formed and processed as blades, rolling shutter springs for window or door, trowels.

Shanghai metal Corporation is a professional manufacturer and supplier of Spring Steel Strip with high quality and reasonable price. If you want to know more about Spring Steel Strip products or Spring Steel Strip price please feel free to contact us, we will reply you within 24 hours.
