Welding

the welds are done fully automated for consistency and integrity.

with lean welding craft for creating the strong joint strength and eliminating the defect.

The welds are detectd by cerfified method like Dye penetrant, Ultrasonic.


Chrome plating

The rod are induction hardened prio to chrome plating which prevent the rod from bending and scratching.

The rod remain rustless over 100 hours under salt spray test.


Tube
