Specifications Introduction
Prestressed steel wire is a versatile and high-performance product crafted from premium high-carbon steel plates. After undergoing meticulous processes including acid washing, cold drawing, and stabilization post-phosphating, the wire is classified into cold-drawing steel wire and stress-eliminating steel wire based on production techniques. In terms of surface conditions, it is available as plain steel wire, indentation steel wire, and spiral rib steel wire. Particularly, cold drawing wire is directly utilized for prestressed concrete applications, ensuring superior durability and strength.
Raw Material Requirements
The primary materials for prestressed concrete production are high-grade carbon steel wire rods such as SWRH77B or SWRH82B. These wire rods must meet stringent criteria concerning size, shape, weight and tolerance, grade and chemical composition, smelting method, delivery state, mechanical properties, decarbonization layer, microstructure, surface quality, and any special requirements to ensure optimal performance.
Cooling is meticulously controlled using Sterem technology, which achieves an impressive over 85% sotenization rate. The coils produced through standard processes reliably meet the demanding requirements for prestressed concrete steel wire and steel strand production.
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 application of steel wire for prestressed concrete is extensive, covering single-story and multi-story buildings, highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. The applications further extend to modern high-rise buildings, underground constructions, hydraulic buildings, marine structures, airport facilities (including runways and terminals), and nuclear power plant pressure vessels. This versatility makes it indispensable for various structural engineering projects demanding exceptional performance under super-tall, super-span, super-volume, super-large area, and overweight load conditions.
