Specifications Introduction
Discover the unparalleled excellence of our Prestressed Steel Wire, a remarkable innovation meticulously engineered from superior high-carbon steel plates. With precision processes such as acid washing, cold drawing, and stable treatment post-phosphating, this steel wire stands in a class of its own. Classified by cutting-edge production techniques, it includes cold-drawing steel wire and stress-eliminating steel wire. According to surface conditions, it offers varieties such as plain, indented, and spiral rib steel wire. Cold drawing wire is seamlessly integrated into prestressed concrete post cold drawing, ensuring unmatched reliability and performance.
Raw Material Requirements
The bedrock of prestressed concrete is the superior carbon steel wire rods, like SWRH77B or SWRH82B. These exceptional wire rods must adhere to stringent criteria, encompassing size, shape, weight, allowable deviation, grade, chemical composition, smelting method, delivery condition, mechanical properties, decarbonization layer, microstructure, surface quality, and any special requirements. Adherence to these standards guarantees peak performance in all applications.
Cooling is expertly managed using advanced Sterem technology, achieving an exceptional Sotenization rate exceeding 85%. Coils produced via these state-of-the-art processes consistently meet and often surpass the stringent production demands for prestressed concrete steel wire and steel strand.
Standards of Steel Wire for Prestressed Concrete
The recognized standards are GB/T5223-2014Prestressed concretesteel wire, conforming toASTM 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,and more.
Applications for the Reinforcement of Concrete Constructions
Our steel wire for prestressed concrete is an essential element for the construction of single-story and multi-story houses, highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. Its critical role extends to modern high-rise buildings, subterranean structures, hydraulic buildings, marine structures, and airport constructions, which include runways and terminals. Additionally, this versatile steel wire is vital for nuclear power plant pressure vessels. Supporting various industries, it serves as the backbone for super-tall, super-span, super-volume, super-large area, and overweight load constructions, offering a vast array of shapes and structural engineering functionalities.
