Product Description

Product Description

Hollow rebar as a professional structural material, its characteristics are relatively thin, but also has a high strength and good durability.Prestressing screw bars are rolled externally threaded in large diameter, high strength, high dimensional accuracy of straight bars. The bars can be connected at any cross section though coupling or screwed anchored.Prestressing screw bars are widely used in large-scale water conservancy projects, industrial and civil construction of continuous beam and large frame structure, roads, railways and middle bridges, nuclear power plants and other projects anchor. It is easy for connection, the anchor is simple, strong adhesion, tension anchor is safe, reliable, easy using, etc., and also saving steel, reducing component size and weight.

Features and advantages:
1) High strength: Because the spiral steel pipe is welded with high-strength steel plate, it has high strength and toughness, and can withstand greater internal and external pressure.
2) Good welding performance: The spiral steel pipe is produced by continuous welding method, and the weld has a high quality to ensure the strength and sealing performance of the weld.
3) Accurate size: The use of advanced production technology and equipment, can ensure the dimensional accuracy and surface finish of the steel pipe, easy to install and connect.
4) Strong adaptability: Spiral steel pipe can be produced according to engineering needs of different diameters, wall thickness, length and material of steel pipe, suitable for a variety of engineering environment and conditions.
5) Excellent corrosion resistance: the surface of the steel pipe can be treated with anti-corrosion treatment, such as epoxy resin coating, asphalt coating, etc., to increase the corrosion resistance of the steel pipe and extend the service life.
6) Environmental protection and energy saving: In the production process of spiral steel pipe, the use of high-frequency electromagnetic field heating can effectively reduce energy consumption and reduce environmental pollution.
7) High economic benefits: compared with seamless steel pipe, spiral steel pipe has lower production cost, relatively economical price, and has better performance and application range.
In summary, spiral steel pipe is widely used in various engineering fields because of its high strength, good welding performance, accurate size, strong adaptability, excellent corrosion resistance and high economic benefits.
