Specifications Introduction
Prestressed steel wire represents the pinnacle of innovation in steel manufacturing, crafted from superior high-carbon steel plates through meticulous processes like acid washing and cold drawing, or through stable treatments post-phosphating. Depending on the production technology, our offerings include the enduring cold-drawing steel wire and the resilient stress-eliminating steel wire. The surface conditions further diversify into plain, indented, and spirally ribbed steel wires. Cold drawing wire is specially optimized for use in prestressed concrete, delivering performance and reliability.
Raw Material Requirements
For prestressed concrete, only the finest materials are used. High-quality carbon steel wire rods, specifically of the SWRH77B or SWRH82B type, are integral to our products. These materials are meticulously evaluated on parameters such as size, shape, weight, allowable deviation, grade, chemical composition, smelting method, delivery state, mechanical properties, decarbonization layer, micro-structure, surface quality, and other specialized requirements to ensure unparalleled performance.
Our cutting-edge cooling process, governed by advanced Sterem technology, attains an impressive sotenization rate exceeding 85%. This ensures that our coils, produced via standard processes, reliably meet the rigorous demands of prestressed concrete steel wires and strands, guaranteeing optimum strength and durability.
Standards of Steel Wire for Prestressed Concrete
Adhering to globally recognized standards, our products meet the stringent requirements of GB/T5223-2014, ensuring they are at the forefront of quality and consistency. Prestressed concrete steel wire, according to ASTM A421-16, ASTM A881/A881M -2005, BS5896-2012, EN10138-2:2009, GOST 7348-81, provide benchmarks for our high-quality standards. TU U27.3-136-004-2003, DSTU ISO 6934-2, GOST 7348-81, DSTU ISO 6934 - 2, ABNT NBR 7482:2008, etc. showcase our commitment to global industry standards.
Applications for the Reinforcement of Concrete Constructions
Our steel wire for prestressed concrete finds versatile applications across a wide spectrum of construction projects. From single and multi-story residences to the robust infrastructure of highway and railway bridges, sleepers, and electric poles, our product enhances strength and durability. It extends to pressure water pipes, storage tanks, and water towers, and is a crucial component in modern high-rise, underground, and hydraulic buildings. Further applications include marine structures, airport runways, terminal buildings, and nuclear power plant vessels. Engineered to withstand the demands of super-tall, super-span, super-volume projects, our steel wire offers unparalleled versatility across diverse architectural and engineering endeavors.
Ranges of Wire Diameter
Offering a diverse range of diameters from 3.00 mm to 12.00 mm, our products cater to various project specifications and requirements.
Ranges of Strength
Our steel wires boast impressive strength capabilities, ranging from 1470MPa to 1860MPa, ensuring they meet the most demanding structural needs.
