Specifications Introduction
Crafted from the finest high-carbon steel plates, our prestressed steel wire is meticulously produced through an innovative series of processes such as acid washing, cold drawing, and phosphating. This versatile marvel is offered in two primary types based on production methodologies: the robust cold-drawing steel wire and the stress-relieving steel wire. Catering to a diverse range of applications, it is available in three distinctive surface finishes: plain, indented, and spiral ribbed. The cold drawing wire emerges as an ideal solution to significantly enhance the durability and strength of prestressed concrete structures.
Raw Material Requirements
Our top-tier prestressed concrete owes its exceptional quality to the superior caliber of carbon steel wire rods such as SWRH77B or SWRH82B. To uphold the highest standards, these rods must meet rigorous criteria, including precise size, shape, and weight tolerances, superior chemical composition, refined smelting techniques, perfect delivery conditions, outstanding mechanical properties, minimal decarbonization, and impeccable surface quality. Special requirements are scrupulously addressed to ensure unparalleled performance and reliability.
Our cooling procedure, powered by state-of-the-art Sterem technology, guarantees an impressive Sotenization rate exceeding 85%. This ensures that the coils produced meet the rigorous demands of prestressed concrete steel wire and strands, delivering unmatched consistency and top-notch 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 expertly engineered to perform in a comprehensive array of applications. It plays crucial roles in the construction of single and multi-story buildings, highway and railway bridges, sleepers, electric poles, pressurized water pipes, storage tanks, and water towers. Its adaptability extends to modern high-rise edifices, subterranean structures, towering complexes, hydraulic projects, maritime constructions, and airport facilities, including runways and terminals. Perfectly suited for industries requiring super-tall, super-span, super-volume, and ultra-large area constructions, as well as for projects necessitating extraordinary loads, unique shapes, and advanced functionalities in structural engineering.
