The difference between galvanized steel plate and galvalume steel plate

There are various materials used for construction on the market, and many of them are very similar, such as galvanized sheets and galvalume sheets. The properties of these two materials are relatively similar, and many people don’t understand them. What are the differences between them? Next, follow the editor to learn about the difference between Galvanized Steel Sheets and galvalume sheets.

First,there is only one layer of zinc material evenly distributed on the surface of the galvanized sheet in order to prevent corrosion on the surface of the steel plate and extend its service life.The coating of galvalume plate is composed of 55% aluminum, 43.5% zinc and a small amount of other elements.The surface shows a unique smooth, flat and gorgeous star flower, with a base color of silvery white.

Secondly,the corrosion resistance of galvalume sheets is stronger than that of galvanized sheets.The resistance to atmospheric corrosion and moisture gas corrosion of galvalume sheets is better than that of galvanized sheets. It can be used in a variety of internal and external building materials and parts. The special coating structure makes it have excellent corrosion resistance. The normal service life of galvalume sheets is 2-6 times that of ordinary galvanized sheets.

Then,the cost of galvalume sheet is lower than that of galvanized sheet.Galvalume-coated sheets not only save a lot of higher-priced aluminum, but compared with galvanized sheets, the unrolled length of steel coils with the same weight, thickness, and width is about 5% longer, which reduces production costs and increases prices. Enterprises Economic benefits increase.

In summary,galvanized sheets and galvalume sheets each have their own advantages, and they are widely used in people's lives.Specifically used in the following industries: construction industry(Roofs, walls, garages, soundproof walls, pipes, modular homes, etc.), home appliance industry(Air conditioners, refrigerators, washing machines, etc.), automobile industry(Car body, outer panels, inner panels, floor panels, doors, etc.) and other industries(Storage and transportation, packaging, granaries, chimneys, buckets, ship bulkheads, insulation covers, heat exchangers, dryers, water heaters, etc.).
