Specifications Introduction
This high-performance prestressed steel wire is meticulously engineered from premium-grade high-carbon steel plates. It undergoes a sophisticated series of processes, including acid washing, cold drawing, and stable treatment following phosphating. Classified by its production methodology, the steel wire is available as cold-drawing steel wire or stress-eliminating steel wire. Furthermore, it offers a variety of surface finishes, such as plain steel wire, indentation steel wire, and spiral rib steel wire. The cold drawing variant is directly applied to prestressed concrete after the cold drawing process.
Raw Material Requirements
The raw materials essential for manufacturing prestressed concrete consist of top-tier carbon steel wire rods, notably SWRH77B or SWRH82B. These wire rods must adhere strictly to specifications regarding size, shape, weight, and allowable deviation. Additional criteria include grade and chemical composition, smelting method, delivery state, mechanical properties, decarbonization layer, microstructure, surface quality, and any other special requirements.
The cooling process is executed with precision using advanced Sterem technology, achieving a remarkable Sotenization rate exceeding 85%. Coils produced through standardized processes meet the rigorous production standards required for prestressed concrete steel wire and steel strand.
Standards of Steel Wire for Prestressed Concrete
The prevalent standard governing our products is GB/T5223-2014.Prestressed concretesteel wire, in compliance withglobally recognized 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,among others.
Applications for the Reinforcement of Concrete Constructions
This robust steel wire for prestressed concrete is widely utilized in various architectural and infrastructural projects. It supports single-story and multi-story residential buildings, highway and railway bridges, sleepers, utility poles, high-pressure water pipes, storage tanks, and water towers. Additionally, it is employed in constructing modern high-rise edifices, subterranean structures, hydraulic buildings, marine facilities, airport buildings (including runways and terminals), and nuclear power plant pressure vessels. Its versatility extends to super-tall, super-span, super-volume constructions, super-large areas, and heavy load structures, adapting to myriad structural shapes and functions.
