Specifications Introduction
Prestressed steel wire refers to high-grade steel wire crafted from premium high-carbon steel plates through processes like acid washing, cold drawing, and stable treatment post-phosphating. It is categorized based on production technology into cold-drawing steel wire and stress-eliminating steel wire. Surface-wise, it’s segmented into plain steel wire, indentation steel wire, and spiral rib steel wire. The cold-drawing wire is directly utilized for prestressed concrete post cold drawing.
Raw Material Requirements
The primary raw materials for prestressed concrete comprise High-quality carbon steel wire rods, specifically SWRH77B or SWRH82B. Essential requirements for these rods include size, shape, weight, allowable deviation, grade, chemical composition, smelting method, delivery state, mechanical properties, decarbonization layer, micro-structure, surface quality, and special requirements.
Cooling is meticulously managed using Sterem technology to achieve over an 85% Sotenization rate. Typically, coils produced per standard procedures meet the necessary production standards for prestressed concrete steel wire and steel strands.
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
Steel wire for prestressed concrete is essential in single-story and multi-story buildings, highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. Its applications extend to modern high-rise buildings, underground constructions, high-rise structures, hydraulic buildings, marine structures, airport buildings (runways and terminal buildings), and nuclear power plant pressure vessels. It plays a pivotal role in various industries for super-tall, super-span, super-volume, super-large area, and overweight load constructions in diverse shapes and functions.
