Pot Equipment


Overall stiffness and rotational stability are the key to outstanding coating results

DUMA-BANDZINK pot equipment has been designed to achieve maximum rigidity. We strive to not allow any form of distortion on the bearing seat. That drastically minimizes vibrations and zinc coating variations.

Above other positive effects, a significant measurable advantage over competitors can be detected in our pot equipment when producing exposed automotive strip grades or advanced high-strength steel grades (AHSS).

Our new Generation II rigs and arms are individually optimized for each line and roll position in relation to the resulting forces.
