What Is Galvanized Iron Sheet?

Galvanized steel sheet refers to a steel sheet with a layer of zinc on the surface for aesthetics and anti-rust purpose.It is most widely used in buildings and also applied as the base metal of color coated steel. Due to the different galvanizing processes, the zinc spangles will be different, including big spangles, regular spangles, small spangles, and zero spangles.

The substrate is hot rolling and cold rolling steel, which is with high strength, good processability, but easy to corrosion. Through the galvanizing process, it will form a protective layer to prevent the substrate from rusting and prolong its service life. Here is how does the zinc coating work: After zinc and oxygen reactions, there will be an oxide film to isolate the substrate from air and moisture to prevent oxidation. If the zinc layer scratches, somewhere around the zinc will melt to protect bare steel from corrosion.

The zinc layer thickness is usually expressed in Z + number. For example, Z275 refers to 275 g (20 µm) of zinc per square meter, which is the same as the G90 galvanized sheet. According to ASTM standards, G60 means the zinc layer is 180g/m2. By the way, our products will pass through the quality test before delivery. Also, third-party testing is also acceptable. You can find the test report of our DX52D Z140 galvanized sheets for our Iran customer.

GI Sheet Material Types

The commonly used galvanized steel grades are:

Commercial Sheet (CQ);
Forming Steel;
GI Sheet for Structural Use (HSLA);
Deep Drawing Steel Sheet (DDQ);
Extra Deep Drawing Steel (EDDS),etc.

How to Calculate GI Sheet Weight?

The GI sheet weight follows the calculation formula: W= Thickness (mm) * Width (m) * Length (m) * 7.85 (Density of steel = 7.85 kg/m3) + zinc layer weight

Taking gauge 18 GI sheets (G90) for example, the thickness is about 1.31 mm. The zinc layer is about 275 g/m2. So the galvanized sheet weight per square meter is about 10.58 kg. You can roughly get the weight. If your galvanized sheet is 0.7 mm in thickness, 1.2 m in width, and 2.5 m in length, the weight is about 16.5 kg/piece (0.7*1.2*2.5). If you order 50 tons, there will be about 3,000 pieces. You can estimate how many GI sheets are needed for your project easily.

Types of GI Sheets

There are different types of galvanized steel sheets. In terms of the manufacturing process, we divide it into hot-dip galvanized steel sheets and electro-galvanized steel sheets. Hot-dip galvanized sheet is mainly used in construction, home appliances, automobiles, light industry, and other industries. Below are more details for your reference.

  • Hot-dip Galvanized Steel Sheet

Hot-dip galvanized sheet is made by immersing the steel sheet in a molten zinc bath at about 500 °C to attach a zinc layer to the surface. This is the continuous galvanizing process. It will form a protective zinc layer on the surface so that it has good paint adhesion and weldability. It is the most widely used and cost-effective method to prolong the service life of steel sheets. Below is a workflow for your reference.

  • Electro-galvanized Steel Sheet

Electro-galvanizing, also known as cold galvanizing, uses electrolysis to form a uniform and dense layer on the surface of the metal. The anti-corrosion zinc layer can protect steel parts from oxidation corrosion. Also, it can meet decorative purposes. But the zinc layer of the electro-galvanizing steel sheet is only 5-30 g/m2. So its corrosion resistance is not as good as hot-dip galvanized sheets.

Difference Between Hot-Dip and Electro-galvanized Steel Sheets

  • Anti-corrosion

The zinc coating thickness is one of the most important factors matters corrosion resistance. The greater the zinc layer thickness, the better the corrosion resistance. Generally, the thickness of hot-dip zinc coating is more than 30 g/m2, or even as high as 600 g/m2. While the electro-galvanized zinc layer is only 5~30 g/m2 thick. So the former steel sheet is much more corrosion resistant than the latter one. At Wanzhi Steel, the maximum zinc layer is 275 g/m2 (z275 galvanized steel sheet).

  • Method of Operation

The hot-dip galvanized steel sheet is galvanized in a molten zinc bath at about 500 degrees, while the electro-galvanized steel sheet is processed at room temperature by electroplating or other methods. That’s why electro-galvanizing also refers to the cold galvanizing process.

  • Surface Smoothness & Adhesion

The surface of the electro-galvanized steel sheet looks smoother than hot-dip galvanized sheets. But its adhesion is not as good as that of the hot-dip galvanized sheet. If you want only one side galvanized, you can choose the electroplating method. However, if adopting hot-dip galvanizing, both sides are coated with a zinc layer fully.

Hot-dip Galvanizing vs Electro-galvanizing Pipes

  • Price

The price of the hot-dip galvanized sheet is higher than that of the electro-galvanized steel sheet.

  • Applications

The electro-galvanizing is suitable for small workpieces. And the electro-galvanized sheet is suitable for applications that require a high finish and interior applications, such as ceilings, window or door frames, automotive panels. While hot-dip galvanizing steel sheet is more corrosion-resistant, which is a good choice for the outdoor environment. Its uses include roofing, doors, gutters, pipes, etc.

Different Designs of Galvanized Steel Sheets for Sale

According to the design, we can find plain and profile galvanized sheets for sale on the market. Galvanized plain sheets are popular in furniture manufacturing, automobile panels, or as the base metal of PPGI sheets. While after profiling, it is widely used in roofing, shutter doors, wall claddings, floor decks, etc.

2. Is galvanized sheet expensive?

Actually, the galvanized sheet price is similar to the as untreated steel sheets. But 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 900 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?
