Specifications Introduction
Prestressed steel wire, an industry cornerstone, is crafted from superior high-carbon steel plates through a meticulous process that includes acid washing, cold drawing, or stabilization post-phosphating. This versatile product is categorized by its production technique into either cold-drawing or stress-eliminating steel wire. Furthermore, it offers diverse surface finishes such as plain, indentation, or spiral rib steel wire. Specifically, cold drawing wire is esteemed for its direct application in prestressed concrete, serving as a robust reinforcement.
Raw Material Requirements
The foundational elements for prestressed concrete are top-tier carbon steel wire rods, specifically SWRH77B or SWRH82B. These rods demand stringent adherence to criteria including precise dimensions, shape, weight, and permissible deviation. The specifications extend to grade and chemical makeup, method of smelting, state upon delivery, mechanical attributes, decarbonization depth, micro-structure, surface integrity, and any unique requirements.
Advanced Sterem technology governs the cooling process, ensuring an impressive Sotenization rate surpassing 85%. Typically, the coils manufactured through standardized processes align seamlessly with the stringent production requisites for prestressed concrete steel wire and steel strand applications.
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 finds its purpose in a myriad of construction projects, including both single and multi-story buildings, as well as highway and railway bridges. It's indispensable for constructing electric poles, pressure water pipes, storage tanks, and water towers. Expanding its utility, it supports modern high-rise edifices, subterranean structures, towering buildings, hydraulic architectures, maritime structures, and airport facilities such as runways and terminal buildings. This versatile wire is crucial for pressure vessels in nuclear power plants and is adaptable across various industries, excellently catering to super-tall, super-span, super-volume, massive area, and heavy-load structures, regardless of their shape or functional demands.
