Coated Electrodes

Coated Electrodes are the main product of our manufacturing division from the time of our founding and they have obtained various industrial standards and certification.
The welded steel structures in our Coated Electrodes are useful for everyone as a social infrastructure.
In addition, ships using welded steel plates are sailing the world from the frigid cold of the seas in the north to the balmy temperatures of the south seas.
