Deformed Steel Reinforcing Bar has a rougher surface in order to further enhance the bond between the steel bar and the concrete used.
Deformed reinforcing bar, also known as deformed rebar, is a high-strength steel reinforcement product designed to improve the bond between steel and concrete. Unlike standard smooth round bar, deformed bar features a ribbed surface, which enhances its grip within the concrete, reducing the risk of slippage and ensuring greater structural integrity.
Neumann Steel’s deformed reinforcing bar is available in N12/6, N16/6, N20/12, N24/12, N28/12, N32/12, and N36/12, traditionally known in the industry as Y12, Y16, Y20, Y24, Y28, Y32, and Y36. With a 500 MPa tensile strength rating (D500N), deformed rebar provides significantly more strength than round reinforcing bar, making it the preferred choice for a wide range of construction projects.

Why Deformed Rebar is so effective?
The main difference between Deformed Reinforcing Steel bar and regular round steel bar is the surface texture, this enables the concrete to grip the steel bar more effectively. As a result, once the concrete has set, the steel bar is much less likely to slip or shift within the concrete as well creating additional stability.
Deformed bar is rated to 500 MPa (D500N) as opposed to round (smooth) reinforcing bar which is 250 MPa (D250N).
