Specifications Introduction
The prestressed steel wire is a superbly engineered product made from top-tier high-carbon steel plates. This product is manufactured with precision using processes like acid washing, cold drawing, and stable treatment post-phosphating. Leveraging cutting-edge production techniques, it is divided into two categories: cold-drawing steel wire and stress-eliminating steel wire. Depending on the surface conditions, it offers plain steel wire, indentation steel wire, and spiral rib steel wire. This cold drawing wire is expertly applied in prestressed concrete post cold drawing applications, providing unmatched performance and reliability.
Raw Material Requirements
The backbone of prestressed concrete is the supreme quality carbon steel wire rods, such as SWRH77B or SWRH82B. These wire rods must adhere to rigorous standards, including precise size, shape, weight, and allowable deviation. They must meet specific grade and chemical composition, smelting method, delivery condition, mechanical properties, decarbonization layer, microstructure, surface quality, and any additional special requirements. Adhering to these stringent standards ensures exceptional performance during application.
Cooling is meticulously controlled using the advanced Sterem technology, achieving a remarkable Sotenization rate of over 85%. The coils produced through these premium processes not only meet but often exceed the production demands 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
This steel wire for prestressed concrete is a critical component for a range of structures, including single-story and multi-story houses, highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. It plays a vital role in the construction of modern high-rise buildings, subterranean structures, hydraulic buildings, marine structures, airport constructions (such as runways and terminals), and nuclear power plant pressure vessels. It supports various industry demands, particularly for super-tall, super-span, super-volume, super-large area, and overweight load constructions, delivering diverse shapes and structural engineering functionalities.
