The JIS carbon steel SM400B CS plate material useful

The company is a large JIS carbon steel SM400B CS plate steel supplier and exporter specializing in steel coil, steel plate, steel tube and section steel. The company has always put service and quality first, offered reasonable price, taken small profits and quick turnover as the principle, honest and trustworthy as the purpose. The success of the company is not only the hard work and wisdom of all the employees of the company, but also the deep love of our customers. We will continue to achieve new leaps and create greater brilliance of the JIS carbon steel SM400B CS plate enterprise, and make our own contribution to the development of the world economy.

Our steel pipes include four major types which are seamless pipe, ERW pipe, LSAW pipe, SSAW pipe, JIS carbon steel SM400B CS plate. Seamless pipe supply scope is OD 10.3mm--965.2mm, wall thickness 1.0mm--60mm. The ERW pipes production range from OD 21.3mm--660mm, wall thickness 1.0mm--16mm. LSAW pipes can supply with OD 406mm--1524mm, wall thickness 6mm--50mm. SSAW pipes can produce maximum OD 3500mm, minimum OD 219.1mm, wall thickness 3.2--25.4mm.

Looking to the future, our company will make its main business more competitive while carrying out diversified, extensive, green and harmonious development modes, so as to be the most competitive stainless steel JIS carbon steel SM400B CS plate producer in the world as well as a worldwide first-class enterprise. With ten years cooperation with these big mills, now we are the agent of super stainless steel mills in China.

In order to improve the JIS carbon steel SM400B CS plate 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 carbon steel SM400B CS plate coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking JIS carbon steel SM400B CS plate 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.
