ASTM A615 Grade 60 Ss400 S355 HRB335 HRB400 HRB500 Hot Rolled Steel Rebar Iron Deformed Steel Bar Rod

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, or reinforcing bar, is a steel bar most commonly used for concrete and masonry construction projects. It provides stronger structural support than wiring and gives tensile strength to concrete or masonry structures such as foundations, walls, driveways and patios. At ZhengDe Metal, you'll find top-quality rebar in a range of lengths to meet the needs of your next project. 

Steel reinforcement bars or rebars are used to improve the tensile strength of the concrete, since concrete is very weak in tension, but is strong in compression. Steel is only used as rebar because elongation of steel due to high temperatures (thermal expansion coefficient) nearly equals to that of concrete.

Mild steel bar:
The surface of the mild steel bars are plain and round in shape. They are available in various sizes of 6 mm to 50 mm. They are used in concrete for special purposes, such as dowels at expansion joints, where bars must slide in a metal or paper sleeve, for contraction joints in roads and runways, and for column spirals. They are easy to cut and bend without damage.
For structural buildings like bridges and other heavy structures, mild steel bar is not recommended due to no great bonding between concrete and steel, slippage and strength.
 

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.
