Specifications Introduction
Crafted from superior high-carbon steel plates, our prestressed steel wire is meticulously manufactured through a series of advanced processes such as acid washing, cold drawing, and phosphating. This versatile product comes in two main types based on production techniques: the resilient cold-drawing steel wire and the stress-relieving steel wire. For diverse applications, it is available in three distinct surface finishes: plain, indented, and spiral ribbed. The cold drawing wire provides an optimal solution for enhancing the durability and strength of prestressed concrete structures.
Raw Material Requirements
Our premium prestressed concrete is backed by the superior quality of carbon steel wire rods like SWRH77B or SWRH82B. To uphold our high standards, these rods must meet strict criteria, including precise size, shape, and weight tolerances, exceptional chemical composition, refined smelting methods, ideal delivery conditions, outstanding mechanical properties, minimal decarbonization, and immaculate surface quality. Special requirements are carefully addressed to deliver unmatched performance and reliability.
Our cooling process, governed by advanced Sterem technology, guarantees an impressive Sotenization rate surpassing 85%. This ensures that the coils produced meet the rigorous demands of prestressed concrete steel wire and strands, offering exceptional consistency and 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 steel wire for prestressed concrete is engineered to excel across a broad range of applications. It plays a vital role 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, underground structures, high-rise complexes, hydraulic projects, marine constructions, and airport facilities, including runways and terminals. Perfect for industries demanding super-tall, super-span, super-volume, and ultra-large area constructions, as well as projects requiring extraordinary loads, shapes, and functionalities in structural engineering.
