The ‘X’ in REBAR-X stands for EpoXy, EXcellence, and EXtreme Durability.
EPOXY BAR
“The New Era of Corrosion
Free Reinforcement - REBAR-X"
With advanced domestic manufacturing technology based on eco-friendly epoxy resin, we produce both the straight and ribbed sections through a fully automated electronic system to ensure the highest quality.
