Reinforcement Steel Bars (Rebars) are high-strength steel rods used to reinforce concrete structures, enhancing their load-bearing capacity, tensile strength, and durability. They are essential in buildings, bridges, highways, and industrial structures. Rebars comply with standards such as IS 1786, ASTM A615, BS 4449, and AASHTO M31.
Types of Reinforcement Steel Bars
🔹 Mild Steel Bars (Plain Rebars) – Used for small-scale construction & temporary structures
🔹 Deformed Bars (TMT, HYSD, HSD) – Provides better bonding with concrete
🔹 Thermo-Mechanically Treated (TMT) Bars – High-strength, corrosion-resistant & earthquake-resistant
🔹 Epoxy-Coated or Galvanized Rebars – Used in marine & aggressive environments
🔹 Stainless Steel Rebars – High corrosion resistance for bridges & coastal structures
🔹 Welded Wire Mesh Rebars – Used for slabs, walls, and tunnels
