Galvanized Rebar

Rebar, commonly known as hot rolled ribbed bar, is a type of steel bar. The grade of ordinary hot rolled steel bar is determined by its minimum yield point and is denoted by HRB (Hot Rolled Bar) followed by a numerical grade. The letters H, R, and B represent hot rolled, ribbed, and bars respectively. Rebar can be classified into different categories based on its strength, such as HRB300E, HRB400E, HRB500E, HRB600E, etc. The thread specification range for rebar is typically 6-50mm. Commonly used sizes include 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 25mm, 28mm, 32mm, 36mm, 40mm, and so on. The national allowable deviation for rebar is as follows: ±7% for diameters 6-12mm, ±5% for diameters 14-20mm, and ±4% for diameters 22-50mm. Rebar is commonly available in fixed lengths of 9m and 12m. The 9m length threaded rebar is primarily used for normal road construction, while the 12m length threaded rebar is mainly used for bridge construction.
