Introduction to Specifications
Meticulously crafted from superior high-carbon steel plates, our prestressed steel wire undergoes a series of advanced processes like acid washing, cold drawing, and phosphating. This versatile offering is available in two main types based on production techniques: the resilient cold-drawn steel wire and the stress-relieved steel wire. For diverse applications, it is offered in three distinct surface finishes: plain, indented, and spiral ribbed. The cold drawing wire provides an optimal solution for enhancing the durability and strength of prestressed concrete structures, ensuring long-lasting performance.
Raw Material Prerequisites
Our premium prestressed concrete is built upon the exemplary quality of carbon steel wire rods such as SWRH77B or SWRH82B. To uphold superior standards, these rods must adhere to stringent criteria: precise size, shape, and weight tolerances, high-grade chemical composition, refined smelting techniques, ideal delivery conditions, exceptional mechanical properties, minimal decarbonization, and impeccable surface quality. Special requirements are rigorously considered to assure unmatched performance and reliability.
Our advanced cooling process, regulated by cutting-edge Sterem technology, guarantees an exceptional Sotenization rate exceeding 85%. This ensures that the coils produced meet the stringent demands of prestressed concrete steel wire and strands, offering unparalleled consistency and quality.
Prestressed Concrete Steel Wire Standards
The prevailing standards are GB/T5223-2014Prestressed concrete applicationssteel wire, compliant withASTM 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,and other relevant standards.
Applications in Concrete Construction Reinforcement
Our steel wire for prestressed concrete is engineered to excel across a vast array of applications. It plays pivotal roles in constructing single and multi-story buildings, highway and railway bridges, sleepers, electric poles, pressurized water pipes, storage tanks, and water towers. Its versatility extends to modern high-rise edifices, subterranean structures, high-rise complexes, hydraulic projects, maritime constructions, and airport facilities, including runways and terminals. Ideal for diverse industries requiring super-tall, super-span, super-volume, and ultra-large-area constructions, as well as for projects necessitating extraordinary loads, unique shapes, and specialized functionalities in structural engineering.
