Specifications Introduction
Crafted from top-tier high-carbon steel plates, our prestressed steel wire is expertly manufactured through a series of refined processes such as acid washing, cold drawing, and phosphating. This adaptable product is available in two primary types based on production techniques: the robust cold-drawing steel wire and the stress-relieving steel wire. To cater to diverse applications, it is offered in three distinct surface finishes: plain, indented, and spiral ribbed. The cold drawing wire is an ideal solution for enhancing the durability and strength of prestressed concrete structures.
Raw Material Requirements
Our superior prestressed concrete is built upon the exceptional quality of carbon steel wire rods like SWRH77B or SWRH82B. To ensure superior standards, these rods must comply with rigorous criteria, including precise size, shape, and weight tolerances, high-quality chemical composition, advanced smelting techniques, optimal delivery conditions, excellent mechanical properties, minimal decarbonization, and impeccable surface quality. Special requirements are meticulously assessed to ensure unmatched performance and reliability.
Our state-of-the-art cooling process, regulated by cutting-edge Sterem technology, guarantees a remarkable Sotenization rate exceeding 85%. This ensures that the coils produced meet the stringent demands of prestressed concrete steel wire and strands, delivering consistency and exceptional 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
Our prestressed concrete steel wire is engineered to excel in a wide range 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 versatility extends to modern high-rise buildings, subterranean structures, high-rise complexes, hydraulic projects, maritime constructions, and airport facilities, including runways and terminals. Ideal for various industries requiring super-tall, super-span, super-volume, and ultra-large area constructions, as well as projects demanding extraordinary loads, shapes, and functionalities in structural engineering.
