Steel PC strand, also known as prestressed steel strand, refers to a steel product composed of steel wire ropes. Different layers such as galvanized layer/zinc-aluminum alloy layer/aluminum cladding/copper plating layer/epoxy coating surface can be added on its surface to meet different uses. As a wire rope supplier, Huayongxin is committed to producing a wide variety at attractive prices
Highway Work: Bridges
Hollow Core is used for hotels and motels, jail cells
Utility Industry: Concrete Poles
Post Tension Applications: Cable Stay Bridges, Housing, Parking Garages
Mining Industry: Rock anchors and soil anchors to retain mining mesh to restrict falling objects
1. Compared to other strand material, steel PC strands require relatively higher strength and yield strength.
2. Steel PC strands possess great elasticity performance
3. Improvement of service lifetimes by adding various types of layers and surfaces
