As the surface coating of AZ50 galvalume steel coil is an alloy composed of aluminum, zinc and other trace elements, it has outstanding corrosion resistance and gradually replaces galvanized coil. The mixed structure of hot dip aluminum zinc silicon coating has its unique advantages in corrosion resistance. AZ50 aluminized zinc is a high quality corrosion resistant steel. It is made of a combination of aluminum and zinc, with an aluminum content of at least 50%. AZ50 aluminized zinc is not only suitable for the exterior of your house, but also for structural purposes and industrial applications. This alloy has many advantages, including excellent strength, impact resistance and excellent weldability.

PPGL steel is a durable, colorful and economical building material. It is the abbreviation of color coated aluminum-zinc plated steel coil, which is based on aluminum-zinc plated steel coil. The aluminum-zinc coated steel is then continuously painted in coil form. Due to its heat resistance and corrosion resistance, it has become a material for various construction purposes, especially roofs and walls. Because it contains 55% aluminum, the corrosion resistance of PPGL coil is much better than that of PPGI, which can greatly extend the service life.

DX52D galvanized coil is a galvanized steel material with a thin and uniform zinc layer on its surface. This zinc layer can effectively protect the steel coil from corrosion and oxidation. In addition, DX52D galvanized coil also has good processing performance and welding performance, and can meet various building processing and construction needs. DX52D galvanized coil can be used for various welding operations. Since there is a layer of galvanized layer on its surface, you need to pay attention to the protection of the galvanized layer during welding to avoid welding defects.

The coating designation G40 represents the type of coating and the weight of the applied coating. The letter "G" indicates that the coating is galvanized, meaning zinc-based. Meanwhile, the number "40" represents the thickness of zinc on the surface of the steel coil. Galvanized steel coil is covered with a zinc coating to provide corrosion resistance. The G40 protective coating prevents moisture from reaching the steel structure, thereby improving the corrosion resistance of the steel. This can extend the life expectancy of the steel. G40 is the average coat weight and therefore provides moderate protection.

The coating designation G90 represents the type of coating and the weight of the applied coating. The letter "G" indicates that the coating is galvanized, meaning zinc-based. Meanwhile, the number "90" represents the thickness of zinc on the surface of the steel coil. Galvanized steel coil is covered with a zinc coating to provide corrosion resistance. The G90 protective coating prevents moisture from reaching the steel structure, thereby improving the corrosion resistance of the steel. This can extend the life expectancy of the steel. G90 is the large coat weight and therefore provides strong protection.

Galvanized coil is made of a type of steel that is coated with zinc for protection by an electroplating process. The galvanized layer is applied to cold rolled steel at low temperatures. Zinc is generally represented by Z. Z is the abbreviation of English Zinc. For example, the Z80 surface zinc plating content is 80 grams per square. Z150 means that the galvanizing content is 150 grams per square meter, and so on. The number after Z indicates the average coating content at three points on both sides of the galvanized steel in grams per square meter. The general materials of hot-dip galvanizing on the market are: Z80, Z100, Z120, Z140, Z180, Z275, etc.
