Prestressed Material

Cut-To-Length Steel Wire

Cut-To-Length PC steel wire is a steel wire cut to a specified length with high strength and good elastic properties. It is usually made of high-quality carbon steel through cold drawing or cold drawing.

It has the characteristics of high strength, low relaxation, good toughness and fatigue resistance. It can effectively establish and maintain prestress in prestressed concrete structures, improve the crack resistance, rigidity and durability of the structure.

ADVANTAGES

Cut-To-Length PC steel wire is used to make the steel bars in the tension zone of prestressed concrete components. It is widely used in civil engineering fields such as buildings, bridges, and railways. By applying prestress in concrete components, the crack resistance, bearing capacity and durability of the components can be improved.


USE

Application fields:

 

- Mainly used in various prestressed concrete structures, such as bridges, floor slabs and roof slabs of high-rise buildings, hydraulic structures, rock and soil anchoring and other engineering fields.


SPECIFICATIONS

Specifications are usually divided according to diameter and strength grade. Common diameters are 4mm, 5mm, 7mm, 9mm, etc., and strength grades are 1570MPa, 1770MPa, etc. In practical applications, relevant national standards and industry specifications must be followed, such as GB/T 5223 "Steel Wire for Prestressed Concrete".


- 4.0 mm: commonly used for some components with relatively low prestressing requirements and small structural dimensions, such as small prestressed concrete slabs.

- 5.0 mm: widely used and can be used for general prestressed concrete beams and slab structures, and can meet certain bearing capacity and crack resistance requirements.

- 7.0mm: Suitable for large structures with high prestress requirements, such as prestressed beams of large bridges, etc., which can provide a large amount of prestress.

- 9.0mm: Commonly used in large hydraulic structures, giant frames of high-rise buildings and other structures with extremely high prestress requirements. Because of its large diameter, it can withstand greater tension.

In addition, there are some other non-standard or special specifications of fixed-length prestressed steel wires to meet the special needs of specific projects.
