Prestressing screw bars is 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 is 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.    

Threaded screw steel bar is mainly used in building structures, infrastructure, Bridges, roads, tunnels, water conservancy facilities, Marine engineering, dock facilities and other construction and engineering projects. Specific uses include:

1. Building structure: Threaded screw steel bar can be used for strengthening and supporting structural components of beams, columns, walls and other buildings.

2. Infrastructure: Threaded screw steel bar can be used for pile foundation construction, such as bridge piles, high-rise building piles, dock piles, etc.

3. Roads and Bridges: Threaded screw steel bar can be used for connecting parts and supporting members in pavement laying and bridge construction.

4. Tunnel: Threaded screw steel bar can be used for tunnel internal supporting structures, such as arches, walls and foundations.

5. Water conservancy facilities: Threaded screw steel bar can be used for the construction and maintenance of water conservancy DAMS, sluices, DAMS and other water conservancy facilities.

6. Marine engineering: Threaded screw steel bar can be used for structural support in Marine engineering such as offshore platforms, derricks, and submarine pipelines.

7. Dock facilities: Threaded screw steel bar can be used for the construction of dock facilities such as dock piles, unloading equipment and handling equipment.

In short, Threaded screw steel bar plays an important role in a variety of construction and engineering projects, with enhanced strength, durability and load-bearing capacity characteristics.
