Specifications Introduction
Crafted from the finest high-carbon steel plates, our prestressed steel wire is a marvel of modern engineering. It undergoes a series of sophisticated processes including acid washing, cold drawing, and phosphating, resulting in a product that stands in a class of its own. This adaptable product is available in two main types based on production techniques: the robust cold-drawing steel wire and the stress-relieving steel wire. To cater to a multitude of applications, it is offered in three distinctive surface finishes: plain, indented, and spiral ribbed. The cold drawing wire is particularly adept at enhancing the longevity and resilience of prestressed concrete structures.
Raw Material Requirements
Our exceptional prestressed concrete depends on the unparalleled quality of carbon steel wire rods such as SWRH77B or SWRH82B. To uphold our high standards, these rods must meet rigorous criteria, including precise size, shape, and weight tolerances, superior chemical composition, refined smelting techniques, optimal delivery conditions, outstanding mechanical properties, minimal decarbonization, and impeccable surface quality. Special requirements are carefully attended to ensure unmatched performance and dependability.
Our innovative cooling process, utilizing cutting-edge Sterem technology, ensures an outstanding Sotenization rate that exceeds 85%. This guarantees that the coils produced adhere to the rigorous demands of prestressed concrete steel wire and strands, providing unrivaled consistency and excellence.
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 excel across a wide spectrum of applications. It plays crucial roles in constructing 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 edifices, subterranean structures, grand high-rise complexes, hydraulic projects, maritime constructions, and airport facilities, including runways and terminals. Ideal for diverse industries that demand super-tall, super-span, super-volume, and ultra-large area constructions, as well as projects requiring extraordinary load-bearing capacities, architectural forms, and specialized functionalities in structural engineering.
