What is Steel Reinforcement? And REBARS
TYPES OF STEEL BARS Forms of steel bars Mild steel plain bars High strength deformed steel bar Hard- drawn steel wire fabric conforming bar Structural steel conforming to grade MILD STEEL BAR (Fe 250) The mild steel bars are plain round and hot rolled bars. These bars have plain surface and have sufficient bond at their ends hooks and bends at their ends for anchorages these bar bend easily and weldable . mild steel bars defined yield point. Plain mild steel bars strength 250 N/mm2 2) HIGH YIELD STRENGTH DEFORMED BAR (HYSD) The cold working process increases both yield as well as the ultimate strength of steel .the yield stress or characteristic stress is given 0.2%proof stress Increase in tensile strength. Increase in bond strength (About 60% more the plain round bars.) HYSDbars of different grade. Fe 415, Fe500, Fe 550 grade *Advantages of hysd bar Due to high yield strength, the amount of steel required is considerably reduce . *disadvantage of hysd Due to
