Specifications Introduction
Crafted from the finest high-carbon steel plates, our prestressed steel wire is precision-engineered through a series of cutting-edge processes like acid washing, cold drawing, and phosphating. This versatile marvel is offered in two primary forms based on production methods: the robust cold-drawn steel wire and the stress-relieving steel wire. To cater to diverse applications, it is available in three distinct surface finishes: plain, indented, and spiral ribbed. The cold drawing wire emerges as the quintessential solution for amplifying the durability and strength of prestressed concrete structures.
Raw Material Requirements
Our premium prestressed concrete foundation is rooted in the exemplary quality of carbon steel wire rods such as SWRH77B or SWRH82B. To uphold superior standards, these rods are required to meet rigorous criteria, including precise size, shape, and weight tolerances, high-grade chemical composition, refined smelting techniques, perfect delivery conditions, exceptional mechanical properties, minimal decarbonization, and impeccable surface quality. Special requirements are diligently considered, ensuring unmatched performance and reliability.
Our advanced cooling process, powered by cutting-edge Sterem technology, ensures an exceptional Sotenization rate surpassing 85%. This guarantees that the coils produced meet the stringent demands of prestressed concrete steel wire and strands, offering unparalleled 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 in a wide range of applications. It plays vital 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, underground structures, high-rise complexes, hydraulic projects, maritime constructions, and airport facilities, including runways and terminals. Ideal for industries requiring super-tall, super-span, super-volume, and ultra-large area constructions, it is also perfect for projects demanding extraordinary loads, shapes, and functionalities in structural engineering.
