Hot-rolled Rebar Introduction
Rebar is also known as hot rolled ribbed steel bar. .Ordinary hot rolled reinforced its brand by the HRB and brand the yield point of the minimum.H(Hotrolled)R(Ribbed)B(Bars)Hot-rolled Rebar HRB335(20MnSi),HRB400(20MnSiV,20MnSiNb,20Mnti),HRB500.
Refers to the reinforced concrete with steel reinforced concrete reinforcement with straight or plate of strip steel, its appearance is divided into two kinds, light round steel and deformed steel delivery status for the straight bar and wire rod in two. chinacoal05
Rebar in concrete main tensile stress. Deformed bars as a result of the action of rib, and concrete have larger bonding ability, thus better able to withstand the role of external force. Steel is widely used in all kinds of building structure, especially large, heavy, light thin wall and high-rise building structure.

OVERVIEW OF REBAR STEEL Rebar China, also frequently referred to as reinforcing steel or reinforcement steel, is a type of steel bar or mesh of steel wires used as a tension device in reinforced concrete and masonry structures to strengthen the concrete under tension. It is ...
Description of Hot Rolled Steel Strip Hot rolled strip generally refers to a coiled steel strip having a thickness of 1 to 20 mm, and the width is generally 600 to 2000 mm. The hot rolled steel strip can be used directly as a hot rolled steel sheet, or a cold rolled strip can ...
Main Feature of Hot Rolled Steel Plate Hot steel coils production is a rolling procedure that relates rolling steel at a high temperature (usually above 1700°F) and over the recrystallization temperature of steel. When the steel heating temperature is higher than the ...
