The surface of a 5 liter round printing paint can usually has a galvanized layer, which is a special metallurgical structure that can withstand mechanical damage during shipping and use; each part of a 5 liter round printing paint can It can be plated with zinc and is fully protected even in recesses, sharp corners and hidden areas.
The galvanizing process on the surface of the 5-liter round printing paint can is faster than other coating methods and avoids the time required to apply on the job site after installation. In general, the cost of hot dip galvanizing is lower than that of other protective coatings. The reason is very simple. Other protective coatings such as sanding paint are labor intensive processes, whereas hot dip galvanizing processes are highly mechanized and tightly controlled.
The hot dip galvanized layer of the 5 liter round printing paint can can be tested visually and simply on non-destructive coating thickness gauges; the specifications for hot dip galvanizing are generally performed in accordance with BS EN ISO 1461, which limits the thickness of the zinc layer, so its The rust prevention period and performance are reliable and predictable, which is conducive to energy saving and extending the service life of 5 litre round printing paint cans.
