DIN/EN seamless steel pipeDIN is Germany Standardization Commission and Berlin administration organization of standardization. It is goes in for drawing up Germany industrial standard and on behalf of the government to attend international standardization activities. ENS has been adopted by Germany as new DIN EN instead of original DIN standard. There are nearly half EN standards among more than 200 steel products in Germany. DIN and EN are also our leading products, which are exported to many countries and areas.
