Ribbed Rebar (Deformed Steel Bar)
Ribbed rebar, also known as deformed steel bar, is a type of steel reinforcement bar with surface ribs designed to increase adhesion between concrete and steel, enhancing the tensile and bending strength of concrete structures.
In Iran’s construction industry, A2 (equivalent to 340 ribs) and A3 (equivalent to 400 ribs) are the most commonly used grades. Ribbed rebar is widely applied in bridges, buildings, dams, and other civil engineering projects.
Production of Ribbed Rebar at Mihan Noor
Mihan Noor produces ribbed rebar using advanced hot-rolling technology:
- Steel billets are preheated to over 1100°C.
- The billets pass through rolling mills to reduce the cross-section and achieve the desired size.
- Surface ribs are pressed onto the bars.
- The rebar is cut to standard lengths (for straight bars) or collected as coils (wire rod form).
Mihan Noor produces:
- Ribbed bars (straight): Diameters 8–32 mm
- Ribbed wire rod (coils): Diameters 6.5, 8, 10, and 12 mm
This wide range ensures engineers and contractors can select the exact product needed for their projects.
