The outer surface treatment of the product is divided into baking varnish and galvanizing. The steel drum is phosphated before coating to improve the adhesion of the product. The coating is amino baking paint or water-based metallic paint, which has bright colors, bright and hard paint film, and has good weather resistance and impact resistance. , Strong adhesion and other characteristics, the outer surface coating of the steel drum can be sprayed into a single color, two colors, or three colors according to the user's choice. The outer surface of the steel drum can also be coated with a galvanized layer, which is divided into white galvanized and Caixia galvanized. The internal treatment of steel drums includes conventional wiping treatment, high-cleanliness treatment, phosphating treatment and internal galvanizing, external spray paint and internal coating, etc. The internal coating is divided into PVF coating, epoxy phenolic resin coating and water-based internal coating, which can be directly filled with honey , Edible oil and other products, also suitable for the packaging of oil and other chemical raw materials.
Material thickness:
The main materials of steel drums are cold-rolled plates and steel strips. The strength of steel drums mainly depends on the thickness of the steel plate. The introduction of the W-stretching process increases the strength of the steel drums, thereby making it possible to reduce the thickness of the steel drums. The cost of the customer. The thickness of the steel plate is between 0.8-1.2mm, and the body, bottom and lid of the bucket can be combined and processed with steel plates of different thicknesses.
