Specifications Introduction
Meticulously crafted from superior high-carbon steel plates, our prestressed steel wire undergoes a sophisticated series of advanced processes, including acid washing, cold drawing, and phosphating, ensuring optimal performance. This versatile product offers two main types based on production techniques: the resilient cold-drawing steel wire, renowned for its flexibility, and the stress-relieving steel wire, ideal for reducing tension. Catering to diverse applications, it boasts three distinct surface finishes: plain, indented, and spiral ribbed, each designed to meet specific structural needs. The cold drawing wire stands out as an optimal solution for enhancing the durability and strength of prestressed concrete structures, delivering unparalleled performance in critical engineering projects.
Raw Material Requirements
Our premium prestressed concrete is built on the foundational excellence of top-tier carbon steel wire rods, specifically SWRH77B or SWRH82B. To uphold our superior standards, these rods must conform to rigorous criteria, encompassing precise size, shape, and weight tolerances, a high-grade chemical composition, advanced smelting techniques, ideal delivery conditions, and exceptional mechanical properties. Additionally, they must exhibit minimal decarbonization and flawless surface quality. Special requirements are diligently considered to ensure unmatched performance and reliability, providing the highest assurance of quality in every aspect of production.
Harnessing cutting-edge Sterem technology, our state-of-the-art cooling process achieves an impressive Sotenization rate exceeding 85%. This innovation ensures that the coils produced meet the stringent demands of prestressed concrete steel wire and strands, offering unparalleled consistency and quality. Such precision guarantees that every coil will perform to the highest industry standards, meeting the rigorous expectations of modern construction demands with ease.
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 engineered for excellence across a broad spectrum of applications. It plays crucial roles in the construction of both single and multi-story buildings, highway and railway bridges, sleepers, electric poles, pressurized water pipes, storage tanks, and water towers. Its versatility extends to encompass modern high-rise edifices, subterranean structures, vast high-rise complexes, hydraulic projects, maritime constructions, and airport facilities, including runways and terminals. Perfectly suited to industries demanding super-tall, super-span, super-volume, and ultra-large area constructions, it is also ideal for projects requiring extraordinary loads, shapes, and functionalities in structural engineering, ensuring robust support and reliable performance.
