Although the country is highly dependent on imported iron ore, it has established a relatively stable raw material procurement
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),
https://www.facebook.com/reel/3158671220939186 Advantages in Raw Material Costs: Strong Self-sufficiency in Coking Coal: China is relatively rich in coking coal resources, with a high domestic self-sufficiency rate of about 90% for coking coal. This gives Chinese steel enterprises a cost advantage in coking coal procurement, as it reduces the transportation costs
