Dx51d galvanized coil material is a non-ferrous alloy mainly composed of zinc as the matrix and other elements. The main alloy elements are aluminum, copper, magnesium, etc. Zinc alloy has low melting point, good fluidity, easy plastic processing and welding, and is resistant to atmospheric corrosion. According to the manufacturing process, it can be divided into cast zinc alloy and deformed zinc alloy. The commonly used cast zinc alloy is zinc aluminum copper magnesium alloy. Its casting process performance is good, and the cooling rate has little impact on the mechanical properties. It is mainly used to manufacture mechanical parts, toys, decorations, household appliances, etc. The commonly used wrought zinc alloys are zinc aluminum alloy and zinc copper alloy. The former contains 4%~15% aluminum. In order to improve the strength and hardness of the alloy, a small amount of copper, magnesium and other alloy elements are added. It has high strength and is easy to form. It can replace some brass or duralumin to make precision forgings. The latter is 0.7%~1.5% copper, which can increase the strength and impact toughness of the alloy and reduce the plasticity. Zinc copper alloy is suitable for making daily hardware products or replacing part of brass.

Hot-dipped galvanized steel coils are excellent candidate for most processing techniques. Welding, torching, or abrasive sawing galvanized steel is not recommended without proper protection and adequate ventilation. Galvanized hot rolled steel, or mild steel, coils have been dipped into a molten zinc coating, or zinc-iron alloy-coated (galvannealed) by the hot-dipped process (ASTM A653). Hot-dipped galvanize (HDG) can be identified by its crystallization pattern, also known as “spangle” on the surface of the material. Great corrosion resistance, excellent candidate for outdoor use or exposed environments. Common applications include HVAC, flashing, freezers, commercial and architectural uses, electrical boxes, enclosures and housings.

Why Choose Galvanized Steel Coil?

1. Cost-effective Solution

Compared to GL or color coated steel coils, the galvanized coil is the most cost-effective solution but with similar features, such as great corrosion resistance, good appearance, etc.

2. Wide Applications

GI sheet roll is easy to process for different purposes. It is widely used in construction, home appliances, automobile containers, transportation, etc. Besides, it has good coating adhesion and weldability. That’s why it is also an ideal base metal for PPGI products.

3. Easy to Transport

Compared to GI steel sheets, coils are easier to transport. In this way, it will save your shipping cost.
