Specifications Introduction
Prestressed steel wire is a high-quality product crafted from high-carbon steel plates. The manufacturing process involves acid washing, cold drawing, and stable treatment post-phosphating. Depending on production techniques, it branches into cold-drawn and stress-eliminated steel wire. Surface conditions categorize it further into plain, indentation, and spiral rib steel wires. Cold drawing wire is specifically designed for direct use in prestressed concrete applications.
Raw Material Requirements
The primary raw materials for prestressed concrete are top-tier carbon steel wire rods, specifically SWRH77B or SWRH82B. Essential parameters include dimensional accuracy, shape, weight, permissible deviations, grade, chemical composition, smelting process, delivery state, mechanical properties, decarburization layer, micro-structure, surface quality, and any special requirements.
Cooling is meticulously managed through Sterem technology to achieve an impressive 85% Sotenization rate. Coils produced under standard processes meet the stringent demands 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
Prestressed concrete steel wire is indispensable in numerous construction projects, ranging from single-story and multi-story buildings to highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. Its versatility extends to modern high-rise buildings, underground structures, towering edifices, hydraulic and marine structures, airport buildings, and even the pressure vessels of nuclear power plants. It serves across diverse industries involving super-tall, super-span, super-volume, expansive areas, and heavy-load structural engineering.
