Specifications Introduction
Our Prestressed Steel Wire is meticulously crafted from premium high-quality high-carbon steel plates, undergoing a transformative process of acid washing, cold drawing, or a steady phosphating treatment. This versatile steel wire is categorized based on innovative production techniques into cold-drawing steel wire and stress-eliminating steel wire. Furthermore, its surface condition allows it to be classified into plain steel wire, indentation steel wire, and spiral rib steel wire. Particularly, the cold drawing wire is directly utilized in prestressed concrete applications, offering enhanced performance and reliability.
Raw Material Requirements
The cornerstone of our prestressed concrete lies in the utilization of superior High-quality carbon steel wire rods such as SWRH77B or SWRH82B. These wire rods must adhere to stringent requirements concerning dimensions, form, weight, and permissible deviation; they must meet high standards in grade and chemical composition, smelting methodology, delivery state, and mechanical properties. Additional considerations include decarbonization layer, microstructure, surface quality, and any special requirements to ensure exceptional product performance and durability.
Harnessing the power of Sterem technology, we control the cooling process to achieve an impressive Sotenization rate exceeding 85%. Our standard production procedures guarantee that the resulting coil fulfills all the critical criteria for prestressed concrete steel wire and steel strand, promising consistency and dependability in its application.
Standards of Steel Wire for Prestressed Concrete
The current standards are GB/T5223-2014 Prestressed concrete steel wire, according to prestigious standards such as ASTM A421-16, ASTM A881/A881M -2005, BS5896-2012, EN10138-2:2009, and GOST 7348-81, TU U27.3-136-004-2003, DSTU ISO 6934-2, GOST 7348-81, and DSTU ISO 6934 - 2, as well as ABNT NBR 7482:2008, among others.
Applications for the Reinforcement of Concrete Constructions
Our steel wire for prestressed concrete finds its applications in a diverse range of structural marvels, from single-story and multi-story buildings to expansive highway and railway bridges. It's vital for sleepers, electric poles, pressure water pipes, storage tanks, and water towers. Its versatility extends to modern high-rise constructions, subterranean buildings, towering structures, and hydraulic as well as marine edifices. Our product supports infrastructures in airport facilities such as runways and terminal buildings, and is fundamental to the structural integrity of pressure vessels found in nuclear power plants. This extraordinary steel wire caters to the demanding needs of industries dealing with super-tall, super-span, super-volume, and super-large area projects, adeptly handling overweight loads across various architectural forms and functionalities.
Ranges of Wire Diameter
Our product boasts a wire diameter range of 3.00 mm - 12.00 mm, offering flexibility to suit a wide array of construction needs.
Ranges of Strength
Our steel wire is engineered to deliver superior strength, ranging from 1470MPa to 1860MPa, ensuring robustness and durability in demanding applications.
