Which strong strand manufacturers? CASE Chun Peng to find! March is about to become past tense, April is coming soon, Chongqing Chun Peng prestressing strand as the only manufacturer in the Southwest here to congratulate the new and old customers business is booming, and good luck. According to the market, the strand is about prices, so I hope the new and old customers need strand quickly orders, do not hesitate. Prestressed concrete strand mainly to do with the reinforcement of prestressed concrete structures, such as large-span bridges, crane beam, rock anchoring project, multi-storey industrial building railways and highways, the construction industry are used in prestressed concrete members reinforcement steel. Structure in the form of: a surface of six spiral wire arc-shaped groove for SMIC wire, there are around six light SMIC steel round wire spiral groove along the arc-shaped wound tightly together, to engage state, radius r wire diameter circle around the light and SMIC spiral steel surface arc-shaped grooves equal r. Because steel round wire surrounding SMIC light surface contact, increasing the friction between them, in the production of prestressed concrete strand after members put sheets to prevent the generation of SMIC wire slip retraction improve Strand overall tensile strength, improve the quality of prestressed concrete members. Prestressed concrete steel wire strand are efficient steel products with high technological content, good quality products. Widely used in highway, road networks, bridges, sleeper, large stadiums, high-rise buildings, airports, ports, terminals, nuclear power plants, dams, mining tunnels, urban elevated light rail, and many other key projects. Prestressed concrete strand mechanical properties: maximum load, elongation, yield load, relaxation rate. The test results should be consistent with the value specified in GB / T5224-1995.
