Currently, there are numerous types of fasteners, including new type fasteners, steel pipe scaffolding fasteners, cast steel fasteners, T-shaped construction fasteners, concrete sleeper fasteners, wooden sleeper fasteners, rail fasteners, Fosroc fasteners, malleable iron fasteners, scaffolding fasteners, railway fasteners, steel plate stamping fasteners, connecting fasteners, rotating fasteners, and right-angle fasteners.
　　
Steel connectors are generally categorized into cast steel connectors and steel plate stamped/hydraulic connectors. The production process of cast steel connectors is similar to cast iron, whereas steel plate stamped/hydraulic connectors are made by stamping and hydraulic pressing techniques using steel plates of 3.5-5mm thickness. Steel connectors excel in various properties, such as tensile strength, anti-slip, resistance to deformation, anti-pulling, and corrosion resistance. Currently, major cast iron connector manufacturers are concentrated in the Cangzhou area of Hebei, with a market share of about 80%; while the market share of steel connectors is approximately 5-10%, with main producers located in Hebei, Chongqing, Xinjiang, and other regions.
