rebar description

Construction rebar steel is known for its high durability and corrosion resistance. It is designed to withstand the long-term effects of exposure to harsh outdoor conditions, including moisture, sunlight, and chemicals. Rebar steel is commonly used in construction projects because it has a long lifespan and can maintain its strength and integrity for decades even with heavy loads and exposure to the elements. In addition, it is resistant to rust and other forms of corrosion, which makes it an ideal choice for structures that need to withstand heavy rain, saltwater, or other harsh environments.

rebar application

Deformed steel bar is commonly known as hot-rolled ribbed steel bar. It belongs to small section steel and is mainly used for the
skeleton of reinforced concrete building components. In use, it is required to have certain mechanical strength, bending
deformation performance and process welding performance. The raw material billet for the production of rebar is carbon structural steel or low-alloy structural steel treated by sedation melting, and the finished rebar is delivered in hot-rolled forming, normalizing or hot-rolled state.

HRB400 rebar specification

rebar introduction

In the U.S. construction industry, common concrete rebar types include:
ASTM A615 Grade 40
ASTM A615 Grade 60
ASTM A706 Grade 60
ASTM A767 Grade 60

The following are some common steel bar types and their corresponding international standards:
HRB335/400/500: Chinese standard steel bar, also known as hot-rolled ribbed steel bar.
ASTM A615 Gr. 40/60/75: American Standard Steel Bar, also known as Plain Hot Rolled Ribbed Bar.
BS4449 Grade 250/460: British Standard Steel Bar, also known as Hot Rolled Ribbed Steel Bar.
DIN 488 B500B: German standard steel bar, also known as hot-rolled ribbed steel bar.
JIS G3112 SD345/490: Japanese standard steel bar, also known as hot-rolled ribbed steel bar.
The specific chemical composition, mechanical properties and size requirements of these steel bar types are different, so in the specific construction project, the appropriate steel bar material should be selected according to the design requirements.
