Specifications Introduction
Delve into the realm of high-quality engineering with our Prestressed Steel Wire, crafted meticulously from premium high-carbon steel plates. These wires undergo rigorous processes such as acid washing, cold drawing, and stable phosphating treatments. Based on advanced production technologies, our steel wire is available in two distinct types: cold-drawn steel wire and stress-relieved steel wire. Depending on surface characteristics, choose from an array of finishes including plain, indentation, and spiral rib steel wire. Cold drawing wire stands out as an optimal choice for prestressed concrete applications.
Raw Material Requirements
Our pursuit of excellence starts with the finest raw materials: High-quality carbon steel wire rods, specifically SWRH77B or SWRH82B. The stringent requirements encompass dimensions, geometric consistency, weight precision, and permissible variances. Each batch adheres to rigorous standards of grade and chemical composition, smelting methodology, delivery condition, mechanical performance, decarbonization layer, microstructure integrity, surface finesse, and any bespoke specifications.
Our advanced cooling process, governed by the cutting-edge Sterem technology, ensures an impressive Sotenization rate exceeding 85%. Typically, the coils produced via our standard processes meet and surpass the stringent demands for prestressed concrete steel wire and strand production.
Standards of Steel Wire for Prestressed Concrete
The current standards are GB/T5223-2014 Prestressed concrete steel wire, according to ASTM 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 revolutionizing the construction landscape, finding applications across single and multi-story buildings, bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. It plays a pivotal role in modern high-rise and underground buildings, high-rise structural complexes, hydraulic constructions, marine infrastructures, airport buildings including runways and terminals, and nuclear power plant pressure vessels. It caters to diverse industries characterized by super-tall, super-span, super-volume, expansive areas, and heavy load projects, adeptly supporting various structural engineering designs and functions.
