Steel Rebar

Rebar (abbreviation of reinforcing bar), which is known as reinforcing steel or reinforcing steel when massed, is a steel rebar that is used as a tensile device in reinforced concrete and reinforced masonry structures to strengthen and help the concrete under Tension is used. Concrete is strong under pressure, but has poor tensile strength. The rebar significantly increases the tensile strength of the structure. The surface of the rebar has a continuous series of ridges, grooves or depressions to create a better bond with the concrete and reduce the risk of slipping.
The most common type of rebar is carbon steel, which usually consists of hot-rolled round rebar with deformation patterns etched into its surface. Steel and concrete have similar coefficients of thermal expansion, so a steel-reinforced concrete structural member will experience minimal differential stress as the temperature changes. Other types of rebars available are stainless steel and composite rebars made of glass fiber, carbon fiber, or basalt fiber. Carbon steel reinforcing bars may also be coated in an epoxy resin designed to resist the effects of corrosion, especially when used in saltwater environments. Bamboo has been shown to be a suitable alternative to steel reinforcement in concrete construction. These alternative types are usually more expensive or may have lower mechanical properties and are therefore often used in specialized construction, where their physical properties meet a specific performance requirement that carbon steel does not.
