Specifications Introduction
Crafted with precision from high-grade high-carbon steel plates, our prestressed steel wire is expertly produced using an array of sophisticated procedures, including acid washing, cold drawing, and phosphating. This adaptable product is available in two primary variants based on manufacturing methods: the robust cold-drawing steel wire and the stress-relieving steel wire. Catering to diverse applications, it offers three distinct surface finishes: plain, indented, and spiral ribbed. Specially designed, the cold drawing wire is the perfect choice to significantly boost the durability and strength of prestressed concrete structures.
Raw Material Requirements
Our premium prestressed concrete is built on the exceptional quality of carbon steel wire rods such as SWRH77B or SWRH82B. To ensure the highest standards, these rods must meet comprehensive criteria, including precise size, shape, and weight tolerances, superior chemical composition, advanced smelting techniques, optimal delivery conditions, outstanding mechanical properties, minimal decarbonization, and perfect surface quality. Special requirements are rigorously evaluated to guarantee unmatched performance and reliability.
Our innovative cooling process, controlled by advanced Sterem technology, boasts an impressive Sotenization rate of over 85%. This ensures that the coils produced fulfill the rigorous demands of prestressed concrete steel wire and strands, offering unmatched consistency and quality.
Standards of Steel Wire for Prestressed Concrete
The current standards are GB/T5223-2014Prestressed concretesteel wire, according toASTM A421-16, ASTM A881/A881M -2005, BS5896-2012, EN10138-2:2009, GOST 7348-81,TU U27.3-136-004-2003, DSTU ISO 6934-2, GOST 7348-81, DSTU ISO 6934 - 2, ABNT NBR 7482:2008,etc.
Applications for the Reinforcement of Concrete Constructions
Our steel wire for prestressed concrete is meticulously engineered to excel across a wide spectrum of applications. It plays essential roles in the construction of both single and multi-story buildings, as well as in highway and railway bridges, sleepers, electric poles, pressurized water pipes, storage tanks, and water towers. Its adaptability also extends to modern high-rise buildings, subterranean structures, large-scale complexes, hydraulic projects, maritime constructions, and airport facilities, including runways and terminals. This makes it the ideal choice for diverse industries requiring super-tall, super-span, super-volume, and ultra-large area constructions, as well as for projects demanding extraordinary loads, shapes, and functionalities in structural engineering.
