Specifications Introduction
Prestressed steel wire, a term that epitomizes excellence, is meticulously crafted from premium high-carbon steel plates. This process involves acid washing, cold drawing, and subsequent stable treatment post-phosphating. Our production technology bifurcates into two distinguished types: the precision-made cold-drawing steel wire and the robust stress-eliminating steel wire. Additionally, based on surface finish, they are categorized into plain, indentation, and the innovative spiral rib steel wire. Cold drawing wire stands as the quintessential choice, directly serving prestressed concrete applications.
Raw Material Requirements
Our prestressed concrete solutions are rooted in superior quality, utilizing carbon steel wire rods like SWRH77B or SWRH82B. The essential criteria for these wire rods encompass meticulous attention to size, shape, weight, and allowable deviation. Additional focus areas include grade and chemical composition, precision smelting methods, delivery state, mechanical robustness, minimized decarbonization layers, optimal micro-structure, pristine surface quality, and the accommodation of bespoke requirements.
Ingeniously employing Sterem technology, we meticulously control cooling to achieve an impressive Sotenization rate exceeding 85%. This cutting-edge process ensures that the coils produced meet the stringent standards required for high-performance prestressed concrete steel wire and strands.
Standards of Steel Wire for Prestressed Concrete
The current standards are GB/T5223-2014 Prestressed concrete steel wire, according to international standards such as 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
Our premium steel wire for prestressed concrete finds its application in diverse construction projects, including single and multi-story buildings, highways, railways, bridges, sleepers, electric poles, and more. It extends its utility to modern high-rise buildings, underground structures, hydraulic buildings, marine structures, and across airport infrastructures such as runways and terminals. The versatility of this product caters to specialized industries in super-tall, super-span, super-volume, and super-large area projects, addressing various structural engineering challenges with unrivaled strength and functionality.
