Dx51d galvanized sheet 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.

FAQs of Galvanized Sheet

1. What is the thickness of GI sheet?

The common thickness of the GI sheet is 0.12 mm – 1.5 mm. At Wanzhi Steel, we have quality galvanized sheets for sale from 0.12 mm to 4 mm. You can choose according to your needs.

2. Is galvanized sheet expensive?

the galvanized sheet price ranges from 700-1300 dollars/ton. In general, it is cheaper than galvalume and stainless steel sheets.

3. What is the cost of the galvanized sheet?

The latest FOB galvanized sheet price in 2022 is 700 to 1,300 dollars per ton. It is affected by many factors, such as the zinc coating thickness, market, material, etc.

4. Does galvanized sheet rust?

Yes. But it doesn’t corrode very quickly because of the protective zinc layer. The zinc forms a barrier preventing oxygen and water from the base metal. But when the zinc layer is broken, the base steel sheet will rust. Generally, the thicker the zinc coating, the better the corrosion resistance, and the slower it will rust.

5. How long does galvanized sheet last?

It will last 30-50 years, and even longer, which is mainly influenced by the use environment, zinc coating thickness, etc.

6. What is better stainless steel or galvanized sheet?

In terms of corrosion resistance and durability, the SS sheet will be better than GI sheet. Also, the strength of SS is greater. That is, stainless steel is stronger. While the SS sheet price will be much higher as well. Besides, GI steel is more ductile, which means it is easier to work with. You can choose according to the use purposes and budget.

7. Is galvanized metal sheet heavy?

Actually, the galvanized sheet is not heavy. As mentioned, the GI sheet weight per square (1mm in thickness) is about 7.85 kg. Compared to traditional building materials, GI sheet is much lighter. That’s why it is widely used as a roofing material.

8. What is galvanized metal sheet made of?

Galvanized sheet is made of iron or steel and zinc coating.

9. Where to buy galvanized sheet for sale (with tips)?

Most investors would like to buy from galvanized steel factories in China because of the lower price. Just remember to find a reliable supplier. Before purchasing, please confirm some details, including specifications (thickness, width, length), zinc coating thickness, corrugations, quantity, etc. The MOQ of Wanzhi Steel is 25 tons. Welcome to talk with us for more details.

10. Is galvanized steel sheet good for the outdoors?

Yes, especially the hot-dip galvanized sheet is suitable for outdoor uses due to its excellent anti-corrosion.

11. Is galvanized steel magnetic?

The answer is Yes. Galvanized steel is magnetic. It keeps the properties of the base
