Specifications Introduction
Prestressed steel wire epitomizes excellence, crafted from superior-grade high-carbon steel plates. Through meticulous processes such as acid washing, cold drawing, and stabilization post-phosphating, it transforms into a pivotal building material. Depending on the production technique, it branches into cold-drawing steel wire and stress-eliminating steel wire. Surface conditions further classify it into plain steel wire, indented steel wire, and spiral rib steel wire. Notably, cold drawing wire is directly applied in prestressed concrete post-process.
Raw Material Requirements
Prestressed concrete demands raw materials of unmatched quality. Premium carbon steel wire rods, specifically SWRH77B or SWRH82B, are essential. Stringent criteria envelop these rods, focusing on dimensions, form, mass and permissible deviations, grade, chemical composition, smelting approach, delivery condition, mechanical attributes, decarbonization layer, microstructure, surface excellence, and specialized specifications.
Sterem technology meticulously governs cooling to achieve an impressive over 85% Sotenization rate. Under typical conditions, the produced coil seamlessly supports the stringent production needs of prestressed concrete steel wire and steel strand.
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
The versatility of steel wire for prestressed concrete is showcased in an array of applications: from single-story and multi-level homes to robust highway and railway bridges, and from essential infrastructure like sleepers and electric poles to pressure water conduits. It extends into storage tanks, water towers, modern skyscrapers, subterranean structures, towering edifices, hydro structures, marine facilities, airport constructions including runways and terminals, and pressure vessels in nuclear power plants. This material caters to industries requiring super-tall, super-span, super-volume, expansive area, and hefty load-bearing solutions, adaptable to myriad architectural forms and functionalities.
