Specifications Introduction
Crafted with precision from high-quality high-carbon steel plates, our prestressed steel wire undergoes an intricate series of advanced processes including thorough acid washing, precise cold drawing, and meticulous phosphating. This adaptable product is available in two distinctive types determined by its production technique: the robust cold-drawing steel wire and the innovative stress-relieving steel wire. Catering to a wide range of applications, it is offered in three unique surface finishes: plain, indented, and spiral ribbed. The cold drawing wire is an ideal choice for significantly boosting the durability and strength of prestressed concrete structures, ensuring long-lasting performance.
Raw Material Requirements
Our superior prestressed concrete is founded on the remarkable quality of carbon steel wire rods such as SWRH77B or SWRH82B. To uphold our high standards, these rods must meet rigorous criteria, including exact size, shape, and weight tolerances, and a high-standard chemical composition. They must be produced using refined smelting techniques and delivered under perfect conditions. Exceptional mechanical properties, minimal decarbonization, and impeccable surface quality are mandatory. Special requirements are carefully considered to ensure unmatched performance, reliability, and longevity.
Our state-of-the-art cooling process, powered by the latest Sterem technology, ensures an impressive Sotenization rate surpassing 85%. This guarantees that the coils produced meet the demanding requirements of prestressed concrete steel wire and strands, offering unmatched consistency and superior quality every time.
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 deliver outstanding performance across an extensive array of applications. It plays crucial roles in the construction of single and multi-story buildings, essential highway and railway bridges, durable sleepers, reliable electric poles, pressurized water pipes, and comprehensive storage tanks and water towers. Its adaptability extends to modern high-rise edifices, sophisticated subterranean structures, intricate high-rise complexes, vital hydraulic projects, cutting-edge maritime constructions, and airport facilities, including expansive runways and terminals. Ideal for industries that demand super-tall, super-span, super-volume, and ultra-large area constructions, as well as projects requiring exceptional loads, unique shapes, and advanced functionalities in structural engineering.
