It is a high-strength PC steel bar with excellent adhesion to concrete for the main reinforcement of PC piles and poles (Type D Class 1 compliant).
The irregular PC steel bar "Ulbon(R)" is a high-strength PC steel bar that excels in adhesion performance with concrete and spot weldability. Due to its excellent performance and ease of use, it has received high praise in the pile and pole industry and is widely used as a tensioning material. 【Features】 - Under appropriate working conditions, using a spot welding automatic assembly machine for rebar cage assembly does not significantly reduce mechanical properties. - It has very little relaxation and remains stable even over long periods. - The surface of the steel bar is formed with spiral grooves along its entire length, providing excellent adhesion to concrete. - When unwound, the coil material becomes straight, eliminating the need for correction work. - The cross-sectional shape is uniform along its entire length, allowing for direct rolling screw processing. - Our warm forging system enables head processing without reducing mechanical properties, allowing for economical fixation.
