Specifications Introduction
Meticulously engineered from superior high-carbon steel plates, our prestressed steel wire undergoes a series of sophisticated treatments, including acid washing, cold drawing, and phosphating. Offered in two primary types—resilient cold-drawing and stress-relieving steel wire—this product caters to diverse needs with three distinctive surface finishes: plain, indented, and spiral ribbed. The cold drawing wire is the quintessential choice to significantly bolster the durability and strength of prestressed concrete structures.
Raw Material Requirements
At the heart of our premium prestressed concrete is carbon steel wire rods of outstanding quality, specifically SWRH77B or SWRH82B. These rods are subject to rigorous standards, ensuring precision in size, shape, and weight, exemplary chemical composition, sophisticated smelting techniques, ideal delivery conditions, outstanding mechanical properties, minimal decarbonization, and impeccable surface quality. Every special requirement is carefully addressed to assure unmatched performance and reliability.
Our advanced cooling process, managed by state-of-the-art Sterem technology, achieves an impressive Sotenization rate over 85%. This ensures that the coils produced are perfectly aligned with the demanding requirements of prestressed concrete steel wire and strands, providing unmatched consistency and superior quality.
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
Engineering excellence defines our steel wire for prestressed concrete, which is designed to shine in a vast array of applications. It plays crucial roles in constructing both single and multi-story buildings, highway and railway bridges, sleepers, electric poles, pressurized water pipes, storage tanks, and water towers. Its adaptability extends to cutting-edge high-rise buildings, subterranean structures, colossal complexes, hydraulic ventures, maritime infrastructures, and airport facilities, including runways and terminals. Ideal for industries demanding super-tall, super-span, super-volume, and ultra-large area constructions, as well as projects necessitating extraordinary loads, designs, and functionalities in structural engineering.
