Cold Drawn Steel Profile for Door Hinges, Cold Finished Steel for Hardware Door Shaft Components

In the field of door and window hardware manufacturing, door shafts and hinge pins are core components for door opening and closing. Door shafts bear the weight of door panels and repeated opening/closing forces over long-term use. The surface condition and material strength of components directly affect the smooth operation and service life of doors. Ordinary hot-rolled steel has scale on its sur
