The common calculation formula for Chinese rebar is: weight (kilograms) = diameter (millimeters) × diameter (millimeters) × 0.00617 × length (meters). For example, to calculate the weight of rebar with a diameter of 20 millimeters and a length of 12 meters: First calculate the weight per meter according to
The quality standards of Chinese deformed steel bars in China mainly follow GB1499.2 – 2024 “Steel for the Reinforcement of Concrete – Part 2: Hot – Rolled Ribbed Bars”. The main quality standards include the following aspects: Chemical Composition The main elements include carbon (C), silicon (Si), manganese (Mn),

This gives Chinese steel enterprises a cost advantage in coking coal procurement, as it reduces the transportation costs

For example, in some past years, China’s steel output can reach more than half of the global total output.
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 details are as follows: Chemical composition detection: Testing methods: Commonly used standard testing methods include GB/T
https://www.facebook.com/profile.php?id=61562536147119 The Chinese standards for rebar and foreign standards have some similarities in the following aspects: Basic shape and structural characteristics: Ribbed form: Whether in China or other countries, the surface of rebar usually has rib patterns to increase the bonding ability with concrete. 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
