Cgood steel strip for shutter spring is well-know good quality for this application. We understand that the flexibility is the key for
shutter spring when the door rolling down and rolling up and strip steel can`t be broken when bending. Cgood steel, every year,
exports hundreds of tons of strip steel worldwide for this use and We have great experience, knowing how to solve these problems
and to avoid this problems. From first-rate raw material, cold rolling, quenching and tempering process, de-burring edges, etc, each
production step, is checked carefully in width, thickness, hardness, edge as flexibility. Spring steel strip (c67s and c75s) is most
suitable for shutter spring material.
