Hot dip galvanized

Now the main method of galvanized steel plate surface is hot dip galvanized.

Hot dip galvanizing is developed from the older method of hot dip galvanizing. It has a history of 170 years since it was applied to industry in France in 1836. However, the hot dip galvanizing industry has been developed on a large scale in the past 30 years with the rapid development of cold rolled strip.

The production process of hot galvanized sheet mainly includes: preparation of the original plate → pre-plating treatment → hot dip plating → post-plating treatment → finished product inspection. According to the custom often according to the plating pretreatment method

Different hot dip galvanizing process is divided into two categories: out-line annealing and in-line annealing. That is, wet method (sheet steel hot galvanizing method), annealing outside the line (sheet steel hot galvanizing method), hot galvanizing Wheeling method (strip continuous hot galvanizing method), annealing inside the line Senjimir (Sendzimir) method (protective gas method), Modified Senjimir method, USEO method (with Japanese Kawasaki method), Selas method and Sharon method.

Galvanized sheet main application industry

A large number of galvanized sheets are used in automobile manufacturing, coolers, construction, ventilation and heating facilities

And furniture manufacturing. Galvanizing has become an important anti-corrosion method for steel, and not just because

Zinc can form a dense protective layer on the surface of steel, also because zinc has a cathodic protective effect when

If the zinc coating is damaged, it can still protect the iron base metal from corrosion by cathodic protection.

Construction industry: roof, roof components, balcony panels, windowsills, kiosks, warehouses, shutter doors,

Heaters, rainwater pipes, etc.

Household appliances: refrigerator, washing machine, switchgear, air conditioner, microwave oven, toaster, photocopier,

Vending machines, electric fans, vacuum cleaners, etc.

Furniture industry: lampshade, wardrobe, table, bookshelf, counter, signboard, medical equipment, etc.

Transportation industry: car ceiling, car shell, car board, tractor, tram, container,

Highway wall, ship bulkhead, etc.

Other aspects: instrument case, dustbin, billboard, clock, camera equipment, meter, etc.
