Specifications Introduction
Prestressed steel wire stands as a pinnacle of specialized engineering, meticulously crafted from superior high-carbon steel plates. The production process is a symphony of precision involving acid washing, cold drawing, or post-phosphating stable treatment. Classified by production techniques, our offering includes cold-drawing and stress-eliminating steel wires. Elegantly engineered surface options include plain, indented, and spiral rib steel wires. The cold-drawing wire is seamlessly integrated into prestressed concrete, ensuring unmatched structural integrity post cold drawing.
Raw Material Requirements
Our prestressed concrete products commence with the finest high-quality carbon steel wire rods, specifically SWRH77B or SWRH82B. These wire rods adhere to stringent requirements encompassing size, shape, weight, and allowable deviation. They are crafted with precision-grade chemical composition, smelting methods, and delivered in an optimal state. Our focus on mechanical properties, decarbonization layer, microstructure, and surface quality guarantees exceptional performance, meeting any special requirements needed.
With a meticulous approach to cooling, we employ advanced Sterem technology to achieve a remarkable Sotenization rate of over 85%. Standard coil processing aligns perfectly with the demanding production needs of prestressed concrete steel wire and strands, ensuring dependable quality and consistency.
Standards of Steel Wire for Prestressed Concrete
The current standards are GB/T5223-2014Prestressed concretesteel wire, according 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,etc.
Applications for the Reinforcement of Concrete Constructions
Prestressed concrete steel wire is the backbone of modern construction, offering unrivaled reinforcement for a plethora of structures. Its versatility spans single-story and multi-story houses, crucial highway and railway bridges, resilient sleepers, and durable electric poles. It fortifies pressure water pipes, spacious storage tanks, and towering water towers. Embracing modernity, it supports high-rise buildings, subterranean structures, and hydraulic edifices. Its applications extend to marine structures, expansive airport buildings including runways and terminal facilities, and even the pressure vessels of nuclear power plants. This robust solution addresses the unique demands of super-tall, super-span, super-volume, super-large area, and overweight load projects, showcasing a diverse range of structural engineering capabilities.
