Specifications Introduction
The prestressed steel wire offered by Tianjin Wasungen Metal Products Co., Ltd. is a remarkable engineering marvel, meticulously fashioned from superior high-carbon steel plates. This exceptional wire undergoes an intricate process that consists of acid washing, precise cold drawing, or stable treatment following phosphating. Harnessing cutting-edge production methodologies, this product is classified into two primary types: cold-drawing steel wire and stress-eliminating steel wire. Depending on the surface texture, it branches into plain steel wire, indentation steel wire, and spiral rib steel wire. The cold drawing wire is effortlessly integrated into prestressed concrete following post cold drawing procedures, guaranteeing unwavering reliability and superior performance.
Raw Material Requirements
The essence of prestressed concrete originates from the superior-grade carbon steel wire rods, such as SWRH77B or SWRH82B. These wire rods must adhere to a stringent set of essential criteria, encompassing size, shape, weight and permissible deviation, grade and chemical composition, smelting technique, delivery condition, mechanical properties, decarbonization layer, microstructure, surface finish, and any special requisites. Adhering to these exacting standards ensures peak performance in applications.
Cooling is precisely executed using the innovative Sterem technology, which achieves a remarkable Sotenization rate surpassing 85%. Coils crafted through these meticulous standard processes consistently meet and often exceed the rigorous production expectations for prestressed concrete steel wire and steel strand.
Standards of Steel Wire for Prestressed Concrete
The recognized standards are GB/T5223-2014Prestressed concretesteel wire, conforming 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,and more.
Applications for the Reinforcement of Concrete Constructions
Steel wire for prestressed concrete is a pivotal component, integral to the construction of single-story and multi-story residential buildings, highway and railway bridges, sleepers, electric poles, high-pressure water pipes, storage tanks, and water towers. It is equally vital for contemporary high-rise structures, underground infrastructures, hydraulic edifices, marine structures, airport constructions including runways and terminals, and nuclear power plant pressure vessels. This versatile steel wire serves a multitude of industries, excelling in super-tall, super-span, super-volume, super-large area, and ultra-heavy load constructions, offering a wide array of design and structural engineering solutions.
