Specifications Introduction
Prestressed steel wire stands as the epitome of high-grade engineering, crafted meticulously from top-notch high-carbon steel plates. This exceptional wire undergoes a transformative journey of acid washing, cold drawing, and stabilizing treatment post-phosphating. Delve into its versatile production technologies, presenting two distinct types: the precision-crafted cold-drawing steel wire and the stress-eliminating steel wire. Explore the diversity of its surface conditions, ranging from sleek plain steel wire to the uniquely textured indentation steel wire and the dynamic spiral rib steel wire. The cold drawing wire is a marvel, directly tailored for the demands of prestressed concrete applications.
Raw Material Requirements
The foundational materials for prestressed concrete are premium-quality carbon steel wire rods, specifically the SWRH77B or SWRH82B grades. These rods must adhere to stringent criteria, including precise dimensions, impeccable shape and weight conformity, and allowable deviations. The emphasis extends to grade and chemical composition, sophisticated smelting methods, and delivery states. Additionally, they must showcase outstanding mechanical properties, maintain an optimal decarbonization layer, and present a refined micro-structure and surface quality. There are also provisions for special requirements to cater to advanced engineering needs.
Cooling utilizes the advanced Sterem technology, ensuring a superior Sotenization rate exceeding 85%. The coils produced through this refined process are meticulously crafted to fulfill the stringent requirements of prestressed concrete steel wire and strands, offering reliability and excellence in construction 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
The application spectrum of steel wire for prestressed concrete is vast and varied, serving as a backbone in both single and multi-story buildings, as well as in highway and railway bridges. It is instrumental in the foundation of sleepers, electric poles, pressure water pipes, storage tanks, and water towers. Explore its expansive use in modern high-rise buildings, underground facilities, and complex structures like hydraulic constructions, marine environments, and airport infrastructures, including runways and terminal buildings. Its robust nature also supports pressure vessels in nuclear power plants, and it is a preferred choice across industries demanding super-tall, super-span, and super-volume structures. With capabilities to handle super-large areas and overweight loads, it proves essential in diverse shapes and functional structural engineering.
