The main body of JIS SS400 plates steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main JIS SS400 plates production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.

The trend of international shipping development of large-scale ships and strategic joint ventures puts forward higher requirements for modern ports. Modern ports no longer use the general cargo throughput as a measure sign, and container throughput will become the main sign to measure the role and status of modern ports. The average container capacity in 2000 is 3200teu, and it is expected to be 5500teu in 2020.

In order to improve the JIS SS400 plates 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 JIS SS400 plates coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking JIS SS400 plates 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.

In October, 2018, our Malaysia customer purchased 600 Tons CCS-AH36 Ship Building Steel Plates to use in their shipbuilding project .This customer is a famous shipyard in Malaysia. Their company has the business scope of tourism, JIS SS400 plates shipbuilding, transportation and so on. As a terminal manufacturer, they have strict requirements on quality . After visiting our factory, the customer are very satisfied with the quality of this batch of JIS SS400 plates CCS-AH36 Ship Building Steel Plates.
