Product Description



Galvanizing pots are containers or tanks used in the galvanization process. Galvanization is a method to shield steel and iron from rust by putting a layer of zinc on them. This layer of zinc works like a wall, stopping the metal from touching harmful things in the surroundings.

To ensure the product quality of galvanizing pots, the Bureau of Indian Standards (BIS) has made it mandatory for manufacturers to undergo BIS registration and obtain the BIS ISI mark before selling it in the market. Manufacturers can use the ISI Mark on their products only after obtaining a license from BIS that is granted after BIS registration. The presence of the ISI mark on a product indicates that it complies with BIS's stringent quality standards.
