Specifications Introduction
Prestressed steel wire is a refined and specialized product, meticulously crafted from premium high-carbon steel plates. The production process involves a precise sequence of acid washing, cold drawing, or stable treatment after phosphating. Distinguished by production methods, the steel wire is classified into two categories: the cold-drawing steel wire and the stress-eliminating steel wire. Surface-wise, it includes plain steel wire, indentation steel wire, and spiral rib steel wire. Notably, the cold drawing wire is employed directly for prestressed concrete applications post the cold drawing process.
Raw Material Requirements
The foundation of prestressed concrete lies in the use of exquisite high-quality carbon steel wire rods such as SWRH77B or SWRH82B. These wire rods must meet stringent specifications including size, shape, weight, and allowable deviation. Other critical parameters encompass grade and chemical composition, smelting method, delivery state, and mechanical properties. Additionally, the decarbonization layer, microstructure, surface quality, and any specialized requirements must be adhered to for optimal performance.
Cooling is expertly controlled with the cutting-edge Sterem technology, ensuring a remarkable Sotenization rate exceeding 85%. Typically, coils produced through these standard processes meet the exacting production demands for prestressed concrete steel wire and steel strand, delivering unmatched quality and reliability.
Standards of Steel Wire for Prestressed Concrete
The prevailing standards are GB/T5223-2014Prestressed concretesteel wire, according toesteemed standards like 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,and other industry-recognized benchmarks.
Applications for the Reinforcement of Concrete Constructions
Steel wire for prestressed concrete forms the backbone of numerous construction projects. It is extensively employed in single-story and multi-story residential buildings, highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. Its versatility extends to modern high-rise buildings, subterranean constructions, high-rise structures, hydraulic edifices, marine structures, and airport infrastructure such as runways and terminal buildings. Furthermore, its applications include critical components in pressure vessels for nuclear power plants and span across various industries. The steel wire is suitable for super-tall, super-span, super-volume, super-large area, and overweight load constructions, adapting to diverse architectural shapes and structural engineering functions.
