Steel rebar is a term used for long rods, bars, or nets of wire made from steel to reinforce concrete to give it better tensile strength. Concrete is strong in compression but weak in tensile strength, which means it cannot bear loads well. The use of rebar, made of iron, allows much stronger and more durable concrete to be ready for use in construction; such rebar may improve the strength of concrete to prevent any cracking and weakening under loads. The process of making steel rebar involves the production of different grades, sizes, shapes, and coatings suitable for a specific type of construction. Most often, rebar is made of carbon steel and is used in the construction of buildings, bridges, highways, etc.
