Reinforcing bars, commonly known as rebar, are steel bars or mesh used to strengthen concrete structures. They provide tensile strength, which concrete alone lacks, helping to prevent cracking and structural failure. Rebar is typically placed in concrete before it sets, ensuring a strong bond as the concrete hardens around it. Various grades and coatings of rebar are available to suit different environmental conditions and structural requirements.

The reinforcement may be in the form of "mesh" or rods. The steel reinforcing rods are colloquially called rebar(reinforcement bars).
Reinforcing bars, or rebar, are typically positioned in slabs to enhance tensile strength and stability. They are layered in two main orientations: horizontal (typically in the bottom layer) and vertical (in the top layer), with the bottom layer placed in the tensile zone to resist bending forces. Bars are usually spaced evenly, with proper cover from the concrete surface to prevent corrosion. Additionally, using ties or supports helps maintain the correct positioning and spacing during the pouring of the concrete.

Iron bars come in various types, including mild steel bars, which are versatile and commonly used in construction; rebar, which is specifically designed for reinforcing concrete; and wrought iron bars, known for their malleability and decorative applications. Additionally, cast iron bars are used for their strength and resistance to wear, often in industrial settings. Each type serves different purposes based on their physical properties and intended use.
