Rigging Hardware Hot Forgings

Rigging belongs to the hardware industry, and the most common rigging is mainly the hardware equipment used for ropes to play a fastening role. Therefore, rigging is also a kind of fastener. Rigging also includes metal rigging and synthetic fiber rigging two categories. Commonly used metal rigging mainly includes national standard light and heavy shackles, high-strength shackles, open body turnbuckle screws, malleable steel turnbuckle screws, malleable steel chucks, lifting rings, lifting cargo hooks, rotating hooks, safety buckles, collars, etc. Synthetic fiber slings are mainly ropes made of polyester fiber as raw materials. Qinhuangdao Zhongwei Precision Machinery Co., Ltd. is an enterprise specializing in forging, processing and production of forgings. Rigging Hardware Hot Forgings can be produced according to drawings and chemical composition, and complete free forging, die forging, rough machining, heat treatment and finishing. Long-term cooperation with crane, petroleum, chemical, mining, metallurgy, hydraulic, coking, train, construction machinery and other enterprises.
