According to the latest statistics of alacero, the consumption of finished steel Q355NH cold rolled railway steel strip products in Latin America in 2019 was 64.2 million tons, down 5% from 67.6 million tons in 2018. The decline in steel consumption in the region reflects the economic contraction of Latin American countries, especially the three major economies: Mexico, Argentina and Brazil. The three countries accounted for 87% of the total reduction in Q355NH cold rolled railway steel strip steel consumption in Latin America. Alacero said the main reasons for the decline in steel consumption in the region are the global economic slowdown, the fall in commodity prices, trade disputes between the United States and its partners, the shrinking world trade Q355NH cold rolled railway steel strip and political uncertainty, as well as the negative impact on Latin American countries and their neighbors in terms of investment.

Q345B material is a low carbon alloy steel grade with good overall performance, low temperature performance, cold stamping performance, welding performance and machinability. Q345 serues steel is widely used in bridges, vehicles, ships, buildings, pressure vessels. Q represents the yield of this material, and the number 345 refers to the yield value of this material, which is around 345MPa. As the thickness of the material increases, its yield value decreases.

BBN company has steel plates production workshops and warehouses with a total area of more than 500,000 square meters, and the total inventory of various types of steel exceeds 1 million tons. Relying on world-leading processing equipment and storage facilities, the company has strong steel production and processing capabilities, comprehensive logistics and logistics services, ensuring that it can efficiently complete more than 1 million tons of hot rolled plates processing business each year.

In order to improve the Q355NH cold rolled railway steel strip corrosion resistance and decoration of steel, it is an important content of steel production method to plating or coating a protective layer on the surface of plastic processed steel. The material of protective layer is divided into metal and non-metal. The metal protective layer adopts the methods of electroplating, hot plating and chemical plating. The main Q355NH cold rolled railway steel strip coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking Q355NH cold rolled railway steel strip sheet metal as an example, there are many hot-dip galvanizing methods used in sheet metal galvanizing. Continuous hot-dip galvanizing is one of the main galvanizing methods used in the world.
