Good news! Another Lithuanian customer purchased 550 tons of galvanized coils, which have now been produced and passed strict quality inspections and have been shipped on April 28, 2023. Lithuania is a mature market where Wanzhi Steel has been operating for many years. Wanzhi Steel has been committed to providing customers with cost-effective galvanized steel coils. Please feel free to contact us for a quotation.
The galvanized coil uses a hot-rolled steel strip or cold-rolled steel strip as the substrate and is produced by a continuous hot-dip galvanizing process.
The specification parameter as the below graph.
|Coil Weight||3-20 tons per coil|
|Steel Grade||DC51D+Z, DC52D+Z, DC53D+Z, DC54D+Z|
|Surface Structure||Spangle coating, minimized spangle coating, spangle-free|
|Surface Treatment||Passivation(C), Oiling(O), Lacquer sealing(L), Phosphating(P), Untreated(U)|
|Package||Standard export package|
1. Low processing cost: the cost of hot-dip galvanizing and anti-rust is lower than that of other paint coatings;
2. Durable: The metallurgical bond between the galvanized layer and the steel becomes a part of the steel surface, so the durability of the coating is better
3. Comprehensive protection: every part of the plated parts can be coated with zinc, even in the depressions, sharp corners and hidden places can be fully protected
4. Time-saving and labor-saving, simple and convenient inspection
The galvanized coil is a thin steel sheet that is dipped in a bath of dissolved zinc to make a layer of zinc adhere to its surface. Galvanized coils can be divided into hot-rolled galvanized coils and cold-rolled galvanized coils, which are mainly produced by a continuous galvanizing process.
Galvanized coils are widely used in construction, home appliances, automobiles, containers, transportation, and home appliances because of their corrosion resistance, good surface quality, good for deep processing, and economical and practical features. Especially steel structure construction, automobile manufacturing, steel silo manufacturing, and other industries.
Galvanized steel consists of zinc, while Galvalume’s coating consists of zinc, aluminum, and silicone. Both types of metal are great for roofing, and they each have their advantages and disadvantages.
The difference between galvanized and galvalume mainly lies in the difference in the coating. A layer of zinc material is evenly distributed on the surface of the galvanized sheet, which acts as anodic protection for the base metal, that is to say, the alternative corrosion of the zinc material protects the base metal. For the use of metal, only when the zinc is completely corroded can the base material inside be damaged.
The surface coating of galvalume steel is composed of 55% aluminum, 43.5% zinc, and a small number of other elements. Microscopically, the surface of the galvanized coating is a honeycomb structure, and the “honeycomb” composed of aluminum contains zinc. In this case, although the aluminum-zinc coating also plays the role of anodic protection, on the one hand, due to the reduction of zinc content, on the other hand, the effect of anodic protection is greatly reduced because the zinc material is wrapped in aluminum and is not easy to be electrolyzed. The galvanized sheet is cut, and it will rust soon when the cut edge basically loses its protection. Therefore, the galvanized sheet should be cut as little as possible. Once cut, the edge should be protected with anti-rust paint or zinc-rich paint to make it The service life of the panels is extended.
In summary, Galvalume is a more durable material and lasts about twice as long as galvanized steel. But the price of galvanized is lower than Galvalume. If you want to buy products with low prices and high-cost performance, it is recommended that you choose galvanized. If you want to buy products with high prices and long service life, it is recommended that you choose aluminum.
