-
Prestressed concrete steel wire is a high-quality steel wire made from high-carbon steel hot-rolled wire rods, which is heat-treated and cold-processed. It is specially designed to meet the requirements of prestressed concrete reinforcement.
The tensile strength of prestressed concrete steel wire is generally above 1470MPa. Over time, intensity levels have transitioned from 1470MPa and 1570MPa to the more common range of 1670MPa to 1860MPa. The wire diameter has also changed, from the initial 3~5mm to the current standard of 5~7mm. These specifications ensure the durability and reliability of the steel wire in withstanding the stress and load requirements of prestressed concrete structures.
The carbon content of this type of steel wire is 0.65% to 0.85%, and the sulfur and phosphorus contents are low, both below 0.035%. Since its industrial production and application in the 1920s, prestressed steel wire has experienced decades of development, resulting in a range of products suitable for a variety of applications. These include cold drawn wire, straightened and tempered wire, low relaxation wire, galvanized wire and scored wire. Prestressed steel wires and prestressed steel strands made from them have become the most widely used types of prestressed steel in the world.
Prestressed concrete wire has several key properties that make it suitable for strengthening concrete structures. Its high tensile strength and resistance to deformation ensure it can withstand significant loads and maintain structural integrity. In addition, the low-relaxation properties of certain types of prestressing wire minimize the loss of tension over time. This helps maintain the structural stability of the concrete. Various forms of wire, such as galvanized and scored, provide additional features such as improved corrosion resistance or better bond strength.
Prestressed concrete wires are classified into different types based on their characteristics and uses. These include low-relaxation serrated PC wire, which improves stress transfer and reduces relaxation characteristics. Another classification is based on the diameter of the wire, with options ranging from 2.64mm for more delicate applications to larger diameters for heavy construction projects.
Prestressed concrete wire is widely used in various construction projects. Mainly used in the construction of bridges, viaducts, high-rise buildings and other large structures that require enhanced load-bearing capacity. The wire's ability to withstand tension and resist stress makes it ideal for reinforcing concrete members. It is also used in the manufacture of precast concrete products, post-tensioned systems, and ground anchoring systems where reliable and durable reinforcement materials are required. Essentially, prestressed concrete wires are critical to ensuring the structural strength and longevity of various concrete structures.
