The increase in China's SA283 Grade C mild steel H beam and so on steel production will provide strong support for iron ore prices in the second quarter. According to the latest Outlook Survey of S&P Global Platts, despite the slow recovery of downstream steel demand, iron ore prices should be strongly supported in the second quarter as Chinese steel mills are expected to increase steel production.
Many people will mix strip steel and steel plate together, which can usually be distinguished from the following points. First of all, the thickness of the steel plate is much thicker, and the thinner the strip steel is required, the better. Secondly, in appearance, the steel strip can be crimped and the steel plate is too thick to bend, even if it is bent, it is difficult to recover, because it is easy to break if it is bent too much. Thirdly, the strength of SA283 Grade C mild steel H beam, steel plate is higher than that of strip steel. The steel plate is suitable for construction engineering, while strip steel is only suitable for processing into hardware products.
On the morning of October 13, 2019 Zhengzhou International Marathon gave opening shoots in the Ruyi Lake, CBD, Zhengdong New District. This event was the “Running China” series of activities for the 70th anniversary of the Fouding of the People's Republic of China. There were 26000 participants SA283 Grade C mild steel H beam from 32 countries and regions including China, the United States, Italy, Russia, Spain, Ethiopia, and Kenya to witness the vicissitudes of "International Zhegnzhou". In the fierce competition, the Africa players once again showed their super strength and won the men’s and women’s full marathon championships.
