What are the materials of Chinese rebar? The materials of Chinese rebar mainly include the following categories: Carbon Structural Steel: Low – carbon Steel: The carbon content is between 0.02% and 0.25%. Rebar made of this material has good toughness and excellent weldability. It is suitable for
Calculation method for theoretical weight The formula for calculating the theoretical weight of rebar is (unit: kilograms/meter), where is the nominal diameter of the rebar (unit: millimeters). For example, for rebar with a nominal diameter of 10 millimeters, the theoretical weight per meter is kilograms/meter. This formula is derived based on the

The shapes of rib patterns
http://facebook.com/profile.php?id=61562536147119 The reasons for the recent price drop of steel in China are as follows: Imbalance between supply and demand: Insufficient demand: Slowing macroeconomic growth: Global economic growth is slowing down. Especially in some major economies, industrial production activities are reduced, leading to a decline in demand for steel. For
Supply situation of steel on August 31:Domestic steel enterprises continue to carry out large-scale reduction of hot metal production. The blast furnace operating rate and capacity utilization rate of 247 long-process steel mills hit a new low in nearly five months. The year-on-year decline continues to expand. The daily average

The infrastructure construction demand in ASEAN regions is strong, and the manufacturing industry is also constantly developing, resulting in
Rebar is the common name for hot-rolled ribbed steel bars. It usually has the following characteristics: I. Appearance and Specifications Rebar has longitudinal ribs and transverse ribs on its surface, thereby enhancing its gripping force with concrete. Its specifications are usually expressed in diameter. Common ones are 6mm,
