Galvanized sheet metal is one of the most commonly used metal sheet types in the manufacturing industry. Many galvanized steel manufacturers and suppliers will tell you that galvanizing is one of the best anti-corrosion measures. Referring to galvanized metal topic, we have to discuss some related knowledge for knowing abuout it deeply. Firstly, we have to know what galvanization is. And hot dipped galvanizing and metallization are both effective methods to protect steel from corrosion. However, they do have some significant differences. It is very important to know all the details before selecting the project anti-corrosion method. Again, What difference between galvalume and galvanized? We have broken these differences so that you can make wise choices.
Galvanization Of Steel, What Is It?
Galvanizing is a manufacturing process that involves coating steel with zinc to prevent it from rusting. Zinc coating is used to protect the base metal. It achieves this by acting as a barrier to various corrosive elements. Therefore, it is sacrificial and provides high-quality and durable steel products. Particularly, galvanized steel plate is one of the most popular types of steel. This is due to its increased strength, durability and formability. Its corrosion resistance greatly improves its practicability.
Galvanization And Metallization
When the metal is hot-dip galvanized, it is sent to the galvanizing plant. Hereby, the metal is cleaned, pretreated, and then completely immersed in the molten zinc kettle to form a uniform anti-corrosion coating by alloying with steel. In addition, thermal zinc spraying, also known as metallization, is the process of coating steel by conveying molten zinc to a properly prepared substrate through air flow. If metallization is used, the zinc coating will be sprayed directly onto the metal. The droplets cool, solidify and form a layered structure on the substrate to form a steadily coating. In fact, both methods have itself advantages and disadvantages.
Galvalume V.S. Galvanized, What Difference?
About galvalume process
Actually, Galvalume Ⓡ, invented by Bethlehem Steel in 1972, consists of 43.5% zinc, 55% aluminum and 1.5% silicon. Galvalume is the trademark name of this series of products, also known as Zincaume. This substrate composition combines the sacrificial properties of zinc with the barrier protection of aluminum. Therefore, it provides excellent performance in almost all applications.
About galvanized process
The galvanized substrate is coated with zinc alloy. The greater the percentage of zinc in the coating, the greater the corrosion protection provided by the panel. G100 and G60 are two commonly used galvanized substrates. These names relate to the total zinc on both sides of the panel surface. G100 products contain 1.0 ounces of zinc per square foot of panel, while G60 substrates contain 0.6 ounces of zinc.
Top 5 Benefits To Choose Galvanized Steel
Actually, It is a cost-effective and environmentally friendly metal, suitable for any manufacturing project. Here are five reasons why you choose galvanized steel sheets and pipes in your next construction project.
1. Galvanized steel is the cheapest processed metal. The hot dip plating process is fast and saves time. Other treatments require painting or spraying, which may take longer to complete.
2. If the matt gray appearance of galvanized steel does not meet your design scheme, your project can be painted or powder coated. These treatments have many options and can be safely applied to galvanized steel. When coating or powder coating is added to the design scheme, additional protective layer will be added to the metal.
3. Typical structures or projects constructed with galvanized steel can last for 50 years. Projects in more urban areas continue for about 25 years because they have more materials to contact.
4. Depending on the item type of metal you select, you may need to check it once or again. The galvanizing process ensures that no area of the metal will be corroded or damaged, which means fast and convenient inspection.
5. Galvanized steel is very durable and can be used under any circumstances. The coating is very reliable, and you can have confidence in the strength of the project. The galvanizing process can protect the steel and provide a durable coating to prevent any corrosion.
