Threaded steel

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

  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

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
