GENERAL INTRODUCTION

 

Chinh Dai Company’s Black Steel Pipes Products are manufactured based on Japanese standard JIS G3466 in order to make a breakthrough solution of quality, price as well as other economic benefits; therefore, they have high durability, perfect resistance to corrosion and rust, and suitability for sea area’s construction (high oxidation).

Our product was pioneered in industrial-scale manufacturing and became an alternative to a large part of the former Black Steel Pipe use.
