Our ANHUI LITONG RARE-EARTH STEEL CABLE CO.,LTD is a profession pc strand manufacture and All of PC Strand production line imported from Italy. We can offer PC strand according to ASTM A 416, BS5896, JIS G3536-88, GB/T 5224 or as your requirements.
1.The product is formed by twisting multiple high steel strength steel wire and eliminating stress (stabilizing treatment) for properly usage of prestressed concrete and similar purpose.
2. It belongs to high-efficicency and high technology steel products with the advantage of saving steel, high tensible strength, well elongation, low relaxation, small stress losing and good performance of anti-fatigue.
3.The pc strand is widely used in highway, bridges, pillow rails, larg sports venues, high-rise buildings, airports, seaports, docks, nuclear power plants, dams, urban overhead roads, light rails and other construction.
Applications
Prestressed cable is mainly for the use of prestressed concrete structure reinforced. such as large –span bridges on railway and highway, overhead crane beam, rock-soil anchoring project, multi-story industrial buildings, stadiums, coal mines and etc.
Features
1. Prestressing Steel Strand has a good corrosion-resistance and less friction of un-bonded tendons and can be easily bended into curve shape.
2. It is suitable for making cast-in-place concrete of long-span and wide building cover, heavy load prefabricated beam and other special structures.
3. It has a lot of characters such as no need of grout hole and grouting, convenient to use, material-saved, bending easily and so on.
