Specifications Introduction
Prestressed steel wire is an exceptional type of steel wire, meticulously crafted from first-rate high-carbon steel plates. This process involves a meticulous series of steps, including acid washing, cold drawing, and a stable treatment post-phosphating to ensure the highest quality. Based on the advanced production techniques employed, it is classified into two distinct categories: cold-drawing steel wire and stress-eliminating steel wire. The surface conditions further define its classification into plain steel wire, indentation steel wire, and spiral rib steel wire. Notably, cold drawing wire is directly utilized for prestressed concrete post cold drawing, making it an indispensable component in the construction industry.
Raw Material Requirements
The foremost raw materials for producing prestressed concrete involve the use of superior-quality carbon steel wire rods, namely SWRH77B or SWRH82B. These wire rods are expected to meet essential requirements which encompass aspects such as size, shape, weight, and allowable deviation. Additionally, they must adhere to specifications related to grade and chemical composition, smelting method, delivery state, mechanical properties, and decarbonization layer. The microstructure, surface quality, and any special requirements must also be meticulously detailed to ensure optimum performance and compliance.
Our cooling process is precisely managed using the state-of-the-art Sterem technology, achieving an impressive Sotenization rate that exceeds 85%. Typically, the coils produced with these standard processes are more than adequate to meet the stringent production demands for prestressed concrete steel wire and steel strand, ensuring supreme quality and reliability.
Standards of Steel Wire for Prestressed Concrete
The prevailing 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
Steel wire for prestressed concrete is extensively used in a diverse array of construction projects. These include single and multi-story houses, highway and railway bridges, sleepers, and electric poles. It is also vital for pressure water pipes, storage tanks, and water towers. Furthermore, its usage extends to modern high-rise buildings, underground buildings, and high-rise structures. In addition, it is integral to hydraulic buildings, marine structures, and airport buildings, including runways and terminal buildings. It serves critical roles in the construction of pressure vessels for nuclear power plants and finds applications across various industries. This wire is essential for super-tall, super-span, super-volume, super-large area, and overweight load projects, accommodating diverse shapes and structural engineering functions with ease.
