- Degreasing
In this stage, Oil or Grease is removed by diping steel fabrication into Acidic/Alkaline solution.
- Rinsing
In this stage, Steel Fabrication is Rinsed, so that no Oil/Grease/Acidic solution is transfected to next stage.
- Chemical Cleaning
In this stage, Steel Fabrication is dipped into Hydrocloric Acid, which removes Rust and Mil Scales on the Steel Fabrication. Hydrocloric Acid is kept at Ambient temperature.
- Rinsing
In this stage, Steel Fabrication is Rinsed, so that no Rust/Hydrocloric Acid is transfected to next stage.
- Flux Treatment
In this stage, Steel Fabrication is dipped into solution of Zinc Cloride + Ammonium Chloride. Flux Treatment, Aids/Helps reaction of steel and Zinc in next stage, by increasing wetablity of the Steel fabrication surface.
- Drying
In this stage, Steel Fabrication is Air Dried, post which coat of flux is formed.
- Galvanize
In this stage, Steel Fabrication is dipped into molten Zinc (+98.5% ) of temperature 450 *C. Min 20 minutes immersion may be required. Due to Reaction of Zinc and Iron, coating are formed on the surface of Steel fabrication, which are Zinc Iron Alloy
- Quench
In this stage, Steel Fabrication is allowed to Air Dry Or dipped into Quench tank to avoid undesirable reaction with atmosphere.
Lightning Arrester and Surge Protection Device
Lightning is electrostatic discharge, causing the instantaneous release of energy. SPD diverts surge to ground without impacting utility supply.
