Lee-Mcall system: In this system, high-tensile alloy steel bars are adopted as prestressing tendons.

Macalloy steel is produced as open-hearth Silicon-Manganese steel, hot-rolled into bars and subsequently processed to have the required physical properties.

The high strength prestressing bars in use are 20 mm. 22 mm. 25 mm. 28 mm, 32 mm and 40 mm.
