Prestressing Bar

Prestressing Bar Introduction:

The raw material of prestressing bar is hot rolled alloy round bar with high tensile strength, which are cold rolled and threaded on part or full length of the bar body. The diameter range of prestressing bar is 35.6mm – 75mm, and other diameter dimensions can be produced by customer’s request.

Why Buy Prestressing Bar from Longteng:

Longteng is a manufacturer with heat-treatment for increasing tensile strength and mechanical characteristics of steel round bars and rebars. These round bars and rebar are then threaded, anti-corrosion treated for high strength structural use. High quality prestressing bars manufactured by Longteng has greater ductility, tensile strength and yield strength, it can be bent over 100 degrees at tight radii without fracture. It is widely used in construction for permanent or temporary prestressing.

• Prestressing bar is fabricated with high quality thread, which keeps high fatigue resistance in stress corrosion situation.
• Each single prestressing bar shall be tested of guaranteed tensile strength in the production process.
• Thread on prestressing bar shall be fabricated with high accuracy to make the tightening work easy and accurate.
• Prestressing bar length can reach up to 11 m and can be connected with sleeves to be longer with the same strength.

What is Prestressing Bar System Composed of?

Prestressing bar system works by trans-passing the press load to bar body and finally on the structure, besides the prestressing bar, the other accessories can be a nut and washer, a nut with a spherical seat, a spherical nut and a spherical washer, or a threaded end plate.

Prestressing Bar Functioning in Building Structure

• Excellent Mechanical Property
  Longteng prestressing bar or prestressed bar is manufactured beyond the requirement standard for fatigue resistant test and tensile stress test. Failure load on the bar with coupler and other anchorage parts is more than 95% of the prestressing bar.
• Perfect Corrosion Resistance
  As prestressed bar works in stressed condition, it shall be tested for anti-corrosion ability in stressed state. Longteng also considers the conditions of exposure, the anti-corrosion treatment shall be chosen according to the working environment. Usually prestressed bar system is designed for grouted construction. In addition, they are sometimes used as external tendons with various types of corrosion protection.
