EN10028-2 boiler steel is mainly to materials used to make superheaters, main steam pipes and heating surfaces of boiler fire chambers.
Henan BEBON Iron & Steel Co., Ltd was founded in 2000, which initially focus on providing high-quality steel products to serve for China's rapid infrastructure development. Based on the advantages of steel resources in domestic market and good reputation, combining with the huge international market demand for steel products, BEBON started the international business in 2010 and successfully being approved and certified by ISO9001:2008, the Registration number is 626014Q11531R0S. With the quality steel products and professional service, BEBON was award the international acclaim from infrastructure, shipbuilding, petroleum industry etc., and gradually grow into a bright star in the steel export industry .
With the exploration and innovation of Bebon people, BEBON gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel, and established our own Machining processing center in order to meet customer's diverse requirements.
