The core difference between galvanized drip coating and normal galvanization

Process flow: Normal galvanizing typically includes steps such as pickling, water washing, electrolytic cleaning, drying, hanging, immersion in molten zinc, cooling, polishing, weighing, and packaging. However, zinc dripping is not a separate galvanizing process; it refers to the phenomenon where the zinc layer flows down on vertical surfaces due to an excessively thick zinc layer or improper drying during the galvanizing process. This may be related to process control, but it is not a standard process flow

 Surface quality: Normally, galvanized surfaces are smooth and uniform, with a stable and even zinc layer thickness. However, zinc run-off can cause the surface to become rough, resulting in zinc nodules and run-off marks, which affect the appearance and corrosion resistance.

 Application areas: Normal galvanization is widely used in construction, automotive, home appliances, and communications, and is suitable for mass production and products with high surface requirements. However, the galvanization sagging phenomenon is typically considered a process defect and is not suitable for applications that require high surface quality; it may only be used for repairing or reinforcing the surface corrosion resistance of certain special steels.
