Galvanized Steel Plate and Sheet

Galvanized steel sheets and plates are intended for use where greater corrosion protection is required without painting.Qinghe Steel stocks many sizes in precut sizes, full mill sizes or we can hot dip virtually any size and quantity required for your welding or construction project. Galvanized sheet / plate can be cut, machined or welded by common methods used for regular steel, but adequate ventilation should be used to avoid inhalation of fumes when heated.

Galvanized steel plate or sheet is used for a variety of projects including furniture, car panels, general fabrication, and much more as it is ideal for covering large areas with good protective qualities. This grade of steel also has excellent machinability and good formability properties.

Galvanized steel sheet benefits

Also known as plate, galvanized steel sheets are perfect for use in roofing projects. Seen as a more customizable option to corrugated metal, our carbon steel sheets are hot dipped in zinc to ISO standards for added protection against the elements.

This galvanizing process makes the mild steel sheets perfect for use in outdoor projects like industrial units, residential buildings, and more temporary structures like outbuildings. The hardwearing properties of the material make it a perfect longer-term solution for works that require fortification from the wind and rain. view more about GALVANIZED STEEL

Surface Structure

Normal spangle

Through addition of certain heavy metal element into molten zinc bath, regular spangle pattern is produced on Hot-dip zinc-coated steel sheet.

Minimized spangle

The zinc layer(coating) does Not contain Lead(Pb), which complies with EU WEEE and RoHS directives. This is a non-toxic and environmental friendly material.


During hot-dip galvanizing, only a certain amount of aluminum is added to the zinc solution, and lead-free, antimony, and tin are not added to produce spangle-free products.

Galvanized Steel Plate Metal Gauge & Metal Thickness

A gauge is used to measure sheet metal thickness. A smaller gauge number reflects a thicker sheet metal— standard gauge numbers for steel range from 7 through 28. Regardless of your fabrication needs, the importance of choosing the correct metal gauge for your application cannot be overlooked. Choosing a gauge that is thicker and more resistant to fabrication can adversely affect your projects.

Classification of Galvanized Steel Plate

Galvanized steel plate can be classified based on several factors, including:

Coating weight: Galvanized steel is typically classified based on the weight of the zinc coating applied to the steel. The most common coating weights are G90 and G60, which refer to the amount of zinc coating per square foot of steel.

Coating type: Galvanized steel can be classified based on the type of coating applied. Hot-dip galvanized steel is the most common type, in which the steel is dipped into a bath of molten zinc to create a coating. Electro-galvanized steel is another type, in which the steel is coated with zinc through an electroplating process.

Steel grade: Galvanized steel can also be classified based on the grade of steel used. Common grades include ASTM A653 and ASTM A36, among others.

Surface finish: Galvanized steel can have different surface finishes, such as spangle or no spangle. The spangle refers to the visible crystalline structure on the surface of the steel, which can be classified as regular, minimized, or zero spangle.

How can you tell if something is made of stainless steel or just coated with it (galvanized)?

Stainless steel is a type of steel that contains at least 10.5% chromium, which gives it its characteristic resistance to corrosion and staining. It is a solid material, and its properties are inherent to the metal itself. On the other hand, galvanized steel is a type of steel that has been coated with a layer of zinc to protect it from corrosion. The coating is typically applied through a process called hot-dip galvanizing or electroplating, and it can be identified by its shiny, metallic appearance.

To determine if something is made of stainless steel or just coated with it, there are a few methods you can use:

Magnet test: Stainless steel is generally not magnetic, whereas galvanized steel is magnetic. You can use a magnet to test if the steel is magnetic. If it is, it is likely galvanized steel.

Visual inspection: Stainless steel has a duller, matte finish and is generally not as shiny as galvanized steel. Galvanized steel, on the other hand, has a bright, shiny finish that is easy to spot.

Chemical test: You can perform a simple chemical test to determine if the steel is stainless or galvanized. Apply a drop of a 50/50 mixture of nitric acid and water to the surface of the steel. If it turns a yellowish color, it is likely galvanized steel. If it does not react, it is likely stainless steel.

It is important to note that these methods may not be foolproof and may not work in all situations. If you are unsure about the material of a particular object, it is best to consult with a professional or perform further testing to determine the exact composition of the material.
