-          Material reception: materials brought to our company for galvanization are checked for suitability to galvanization. (material dimensions, paint, welding residue, etc.) Company officials are contacted if there is an unsuitability and a solution is presented. (drilling holes on material to allow zinc flow, cleaning of all paint, etc.) 

-          Hanging of the Material: the suitable hanging method is chosen for the material. 

-          Grease Removal: the material is submerged into alkali bath to remove any possible grease or chemical residues. The bath time depends on the cleanliness of the surface of the material. 

-          Surface Cleaning in Acid: the material is dipped into a 18% HCl bath to remove any rust. Material needs to be bathed in acid to become active for galvanization even if there is no rust on it. 

-          Rinse: material is rinsed in water bath after the acid bath. 

-          Flux Coating: rinsed material is dipped into a bath of 30% NH4Cl-ZnCl2 at 50-70C to allow zinc to coat the surface. 

-          Galvanization: material, cleaned and fluxed, is dipped into melted zinc at 445-465C and is coated with zinc. Materials that can be damaged in water are cooled in the air, otherwise all are cooled in water bath. 

-          Maintenance and Check: galvanized material’s coating thickness is measured with a micrometer. Materials with coating defects are either repaired or recoated. Zinc drippings are filed. 

-          Storing and Transport: Material, checked and maintained, is stored suitable for loading and transported to the companies.

 This is the galvanization process you requested from our company. All operation in our company is conducted with written instructions. All measurements in the instructions are conducted and recorded.
