Drying and preheating: Dry at 120-150℃ for 10-15 minutes to completely remove surface moisture. The surface must be free of water stains and oxidation; otherwise, the galvanized layer may show signs of blistering or exposure to oxidized material. Defects such as those mentioned above; Zinc immersion: The zinc immersion temperature is strictly controlled at 445-460℃. The immersion time is adjusted according to the thickness of the plate. When the thickness is ≤6mm, the immersion time is 1-2 minutes. When the thickness is >6mm, bere a wɔde hyɛ nsu mu no yɛ simma 2-3. Aduru a wɔde yɛ onwini: Fa mframa a ɛma onwini anaa nsu a ɛyɛ nwini di dwuma na ama ayɛ nwini akodu dan mu hyew mu.
