Enhanced Bonding with Concrete: The surface of deformed steel has ridges or ribs that create a mechanical bond with the concrete, improving the overall strength of reinforced concrete and preventing slippage of the steel inside the concrete.
High Tensile Strength: Deformed steel is manufactured in multiple grades like 등급 60 (60,000 psi) 그리고 등급 75 (75,000 psi), ensuring that it can handle heavy loads and extreme stress in various construction projects.
Durability and Corrosion Resistance: Many deformed steel bars are treated to resist corrosion, making them suitable for use in harsh environments such as marine, 산업, or highly humid areas.
Seismic Resistance: Due to its ribbed design and high tensile strength, deformed steel provides enhanced resistance to the forces experienced during earthquakes, making it ideal for construction in seismic zones.
