Specifications Introduction
Prestressed steel wire, crafted from top-tier high-carbon steel plates, undergoes meticulous processes such as acid washing, cold drawing, or stable post-phosphating treatment. Two distinct production technologies categorize it: cold-drawing steel wire and stress-eliminating steel wire. The product's surface can vary, presenting as plain steel wire, indentation steel wire, or spiral rib steel wire. Cold drawing wire directly enhances prestressed concrete by delivering superior strength and performance.
Raw Material Requirements
For the creation of premium prestressed concrete, the raw material of choice is high-quality carbon steel wire rods, specifically SWRH77B or SWRH82B. These rods must meet stringent criteria, including precise size, shape, and weight, alongside permissible deviations. Additionally, they must adhere to stringent standards in terms of grade, chemical composition, smelting methods, delivery state, mechanical properties, decarbonization layer, micro-structure, surface quality, and any specific custom requirements.
The advanced Sterem technology governs cooling to achieve an impressive Sotenization rate of over 85%. The coils produced through this systematic process are well-equipped to meet the demanding standards required for prestressed concrete steel wires and strands.
Standards of Steel Wire for Prestressed Concrete
The prevailing 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 spectrum for steel wire in prestressed concrete is vast, spanning residential structures to transport infrastructure like highway and railway bridges. Its versatility extends to utility poles, pressure pipes, storage tanks, and water towers. These steel wires are integral to modern engineering feats, including towering skyscrapers, subterranean facilities, high-rise structures, and various hydraulic and marine constructions. They're also pivotal in airport infrastructure, nuclear power plant pressure vessels, and more, supporting complex engineering solutions across industries characterized by super-tall, super-span, super-volume, super-large areas, and heavy load demands, with multifaceted architectural designs.
