Specifications Introduction
Crafted from superior high-carbon steel plates, our prestressed steel wire boasts unmatched precision, meticulously manufactured through a seamless integration of advanced processes including acid washing, cold drawing, and phosphating. This versatile marvel is available in two main types based on refined production techniques: the resilient cold-drawing steel wire and the stress-relieving steel wire. To cater to diverse applications, it comes with three exquisite surface finishes: plain, indented, and spiral ribbed, each tailored for specific needs. The cold drawing wire emerges as the optimal solution, enhancing the durability and strength of prestressed concrete structures, ensuring longevity and performance.
Raw Material Requirements
Our premium prestressed concrete is a testament to excellence, relying heavily on the unrivaled quality of carbon steel wire rods such as SWRH77B or SWRH82B. To uphold superior standards, these rods must meet rigorous criteria, including precise size, shape, and weight tolerances, high-grade chemical composition, advanced smelting techniques, ideal delivery conditions, outstanding mechanical properties, minimal decarbonization, and impeccable surface quality. Each special requirement is scrupulously addressed to ensure unparalleled performance and reliability, forming the backbone of our commitment to quality.
Harnessing cutting-edge Sterem technology in our cooling process, we guarantee an extraordinary Sotenization rate exceeding 85%. This advancement ensures that the coils produced not only meet but exceed the stringent demands of prestressed concrete steel wire and strands, delivering unrivaled consistency and quality across all applications, setting a new standard in the industry.
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
Our steel wire for prestressed concrete is meticulously engineered to excel across an extensive spectrum of applications. It plays crucial roles in the construction of single and multi-story buildings, highway and railway bridges, sleepers, electric poles, pressurized water pipes, storage tanks, and water towers. Its exceptional versatility extends to modern high-rise edifices, subterranean structures, towering complexes, hydraulic ventures, maritime constructions, and airport facilities, encompassing runways and terminals. Ideal for industries requiring super-tall, super-span, super-volume, and ultra-large area constructions, as well as for structural engineering projects demanding extraordinary loads, innovative shapes, and multifaceted functionalities.
