One meter of 25 rebar weighs approximately 3.85 kilograms.

The diameter is approximately 25 mm, and the calculation formula is steel bar weight = diameter x diameter x 0.00617 = 25 x 25 x 0.00617 = 3.85. In addition, this formula can also be used to calculate the weight of steel bars of different diameters. Steel bars with larger diameters are heavier and can be used in house construction, road construction and other projects.

Before purchasing rebar, you need to understand the size and dimensions in advance, and then clearly see the surface and quality of the material. However, for some inferior products, there is not much difference in appearance. Diameter observation is also very difficult to distinguish. Measuring tools can be prepared in advance to measure the quality. Rebar from regular manufacturers is usually sold in large bundles. If you see that the rebar is sold in bulk, it means that the manufacturer is not a regular product.

The current situation of the rebar market

From a macro perspective, domestic steel prices fell sharply in 2013, and the prices of Chinese steel products will fall sharply because there has been a problem of overcapacity and The price of iron ore, the main raw material, also fell. China's slowing economic growth is curbing the country's demand for steel and iron ore, dragging prices of both commodities to multi-month lows and putting expansion plans of global iron ore producers at risk.

The trend is not expected to change in the coming months because there is too much capacity and industry consolidation is too slow. At the same time, the problem of oversupply of iron ore has also increased, indicating that its price will continue to fall. In 2013, coal, coke, and steel futures fell together again, while the stock market was stable, and the trend divergence between steel futures and the stock market increased. The reason was the intensified contradiction between supply and demand in the fundamentals of the steel industry chain itself.
