Steel strand is made of carbon Steel Wire after twisting and heat treatment to eliminate internal stress.

Steel strand has high strength and good flexibility, and is especially suitable for prestressed concrete structures with curved reinforcement, large-span or heavy-loaded roof trusses, etc. Steel wire and steel strand are mainly used for long-span and large-load bridges, poles, sleeper rails, roof trusses, large-span crane beams, etc. They are safe and reliable, save steel, and do not need cold drawing, welding joints and other processing, so they are widely used in civil engineering.
