  • In semi-finished depot, products are randomly checked and recorded.
  • Specialized quality controllers check parts quality before galvanizing while all parts are washed with water and acid.
  • Galvanizing process is control by checking chemical analysis, optimum temperature of Zinc furnace.

Final Product

  • Final products are checked for thickness and stickiness of covered Zinc on parts. After packing process, order is controlled by Final Product Quality Inspectors who control bundling, weight of each bundle, right storing and finally right loading on board.
