Application field
It is applied in rail engineering construction, bridge building, etc.

Some cooperation cases
It has participated in the construction of key national and local projects such as the China Pavilion at the World Expo, the Three Gorges Project, the South-to-North Water Diversion Project, Beijing Daxing International Airport, Xiongan Railway Station, the Shijiazhuang Metro System, Taihang Expressway, and Qiancao Railway, and has been widely applied in fields such as rail engineering construction and bridge building.
Wire rods are semi-finished steel products produced through hot rolling processes, typically supplied in coil form for further processing such as drawing, forging, welding, and machining. They are widely used as raw materials in construction, automotive manufacturing, machinery production, and industrial fabrication.
Manufactured from high-quality carbon steel or alloy steel, wire rods offer excellent mechanical strength, flexibility, and ductility. Depending on the grade, they can be processed into various finished products such as steel wires, nails, bolts, screws, mesh, and springs. Their uniform composition ensures stable performance during downstream manufacturing processes.
Wire rods are available in different diameters and specifications to meet diverse industrial requirements. They can also undergo heat treatment or surface treatment to enhance hardness, corrosion resistance, or wear resistance. Due to their versatility and cost-effectiveness, wire rods are an essential material in modern industrial supply chains, supporting large-scale production and infrastructure development.
