Products Description
Steel strands for prestressed concrete are made of the high carbon steel wire rods SWRH82B and have the characteristics of high tensile strength, low relaxation, steady modulus of elasticity, relieved stress, and high adhesion with concrete through continuous drawing with large deduction stranding and stabilization treatment to meet the ASTM A416, BS 5896, and GB/T5224 standards. Such steel strands are primarily used in highways, bridges, key water control projects, anchoring tension members, and lift tension members.
Prestressed electro galvanized steel strand is made of twisting galvanized prestressed steel wire as semi-finished products. Zinc coating has both mechanical protection and electro chemical protection on iron matrix, and has good corrosion resistance.
Material of PC Strands: High carbon steel wire 82B, 77B.
Process of PC Strands: continuous pulling, twist and stabilization treatment.
Product Type of PC Strands :Electric-galvanized zinc PC strands.

Product Feature
Features of PC Strands : high flexion strength ratio, low relaxation, stable elastic modulus, eliminate stress, and firmly combined with concrete.
application
Application of PC Strands: highways, Bridges, housing construction, water conservancy projects, anchoring tension components, lifting tension components, nuclear power plants, etc.
Because of the reaction between zinc and concrete, galvanized products can only be used in non-concrete mines, anchor cable support, external cable cable, etc.
