Post tension bars are designed to create a compressive force within the concrete that helps to counteract the tensile forces that the structure will experience over time. This can improve the integrity and longevity of the concrete structure, making it more resistant to cracking, corrosion, and other forms of damage.
Post tension bars are typically made from high-strength steel and are placed inside precast concrete sections or cast-in-place concrete forms. The bars are then tensioned to a precise level using hydraulic jacks, creating a strong, durable structure that can withstand the test of time.
System Description:
The screw thread steel bars for the prestressing of concrete manufactured by our company is a high tensile alloy steel bar which features a coarse right-hand thread over its full length and available in two standard lengths, namely 9m and 12m,yet,special length is negotiable based on user’s demand subject to the maximum length of 18m.
