Rebar (short for reinforcing bar), known when massed as reinforcing steel or reinforcement steel, is a steel bar used as a tension device in reinforced concrete and reinforced masonry structures to strengthen and aid the concrete under tension. Concrete is strong under compression, but has low tensile strength. Rebar significantly increases the tensile strength of the structure. Rebar's surface features a continuous series of ribs, lugs or indentations to promote a better bond with the concrete and reduce the risk of slippage.

The most common type of rebar is carbon steel, typically consisting of hot-rolled round bars with deformation patterns embossed into its surface. Steel and concrete have similar coefficients of thermal expansion, so a concrete structural member reinforced with steel will experience minimal differential stress as the temperature changes.

Other readily available types of rebar are manufactured of stainless steel, and composite bars made of glass fiber, carbon fiber, or basalt fiber. The carbon steel reinforcing bars may also be coated in zinc or an epoxy resin designed to resist the effects of corrosion, especially when used in saltwater environments. Bamboo has been shown to be a viable alternative to reinforcing steel in concrete construction. These alternative types tend to be more expensive or may have lesser mechanical properties and are thus more often used in specialty construction where their physical characteristics fulfil a specific performance requirement that carbon steel does not provide.

Two craft
The grade of fine-grain hot-rolled steel bar is followed by the English abbreviation of "hot-rolled ribbed steel bar" with the first letter of "fine" in English (Fine). Such as: HRBF335, HRBF400, HRBF500. Applicable grades for seismic structures with higher requirements: Add E after the existing grades (for example: HRB400E, HRBF400E).
Main application: Widely used in the construction of houses, bridges, roads and other civil engineering.

Adequate inventory
Rebar series with nominal diameters of 6, 8, 10, 12, 16, 20, 25, 32, 40, 50mm. The supply length is divided into two types: fixed length and double length. The selection range of export rebar fixed length is 6~12m. The above specifications and sizes have a large stock all the year round.Within 10,000 tons, it can be packaged and shipped within three days.

Attention to detail
The surface quality requires that the end should be cut straight, and the surface should not have cracks, scars and folds, and there should be no harmful defects in use, etc.
The bending degree of rebar and the requirements of the geometric shape of the steel bar The bending degree of the straight steel bar should not affect the normal use, and the total bending degree should not be greater than 0.4% of the total length of the steel bar.

Applicable scene
The market demand for rebar is closely related to the development of the construction industry. With the acceleration of the urbanization process, the demand for construction projects continues to grow, and the demand for rebar is also increasing. The market has the largest demand for rebar with a diameter of 8mm/10mm/12mm. With the advancement of large-scale infrastructure construction, the demand for 14mm/16mm diameter rebar is gradually increasing.
