Cleaning: First, clean the steel grating to remove oil, dust and other impurities on the surface to ensure the adhesion of the coating.
Pickling: Next, the steel grating is soaked in an acidic solution for pickling treatment. Pickling can remove oxides and rust on the surface of the steel plate to prepare for subsequent galvanizing.
Soaking: After cleaning and pickling, the steel grating is soaked in a solution containing zinc salts. During this process, a zinc-iron alloy layer forms on the surface of the steel grating to provide protection and corrosion resistance.
Drying: The soaked steel grating needs to be dried to remove excess moisture on the surface and prevent bubbles and uneven coating.
Cooling: The dried steel grating needs to be cooled to solidify and stabilize the galvanized layer.
Inspection: Conduct quality inspection on galvanized steel grating, including checking the thickness, adhesion, uniformity and other indicators of the coating to ensure that the product meets relevant standards and requirements.
