Key takeaways:

1. The weight of galvanized sheets, used for their anti-corrosive properties, is calculated theoretically based on the substrate steel plate's weight and the weight of the zinc coating, which varies in nominal thickness and can be applied equally or differentially on each side, reflecting the sheet's protective and functional requirements.

2. The galvanization process offers a variety of sheet types and surface coatings, including hot-dip and electro-galvanization, with options for different zinc flower patterns, indicative of the sheet's aesthetic and surface texture, which are tailored to diverse applications and standards.

3. The article provides a comprehensive chart correlating the thickness of galvanized sheets to their weight per square meter, serving as a practical tool for users in industries like construction and manufacturing to estimate material weight for logistics and structural calculations.

Galvanized Sheet Weight Calculator

galvanized sheet

Galvanized sheets are usually delivered based on their theoretical weight, whereas galvanized steel strips are typically delivered based on their actual weight.

The theoretical weight of galvanized sheets takes into account the weight of the cold-rolled or hot-rolled steel plate on which they are based. This weight includes two parts:

  • one is the theoretical weight of cold-rolled or hot-rolled steel plate (substrate) for processing galvanized sheet;
  • the other is the theoretical weight of the galvanized layer.

You can use the below galvanized sheet weight calculator to calculate the weight of the galvanized sheet.

What Is Galvanized Sheet?

Galvanized sheet refers to a steel plate that has a layer of zinc on its surface. Galvanizing is a widely used, economical, and effective method of preventing corrosion.

Approximately half of the world’s zinc production is utilized in this process to prevent corrosion on the surface of steel plates and extend their service life.

Types of Galvanized Sheet?

According to different production and processing methods, galvanized steel sheet can be divided into:

  • hot-dip galvanized steel sheet
  • alloyed galvanized steel sheet
  • electro galvanized steel sheet
  • single-sided galvanized steel sheet
  • double-sided differential galvanized steel sheet
  • alloy and composite galvanized steel sheet
  • color galvanized steel sheet
  • printing coated galvanized steel sheet
  • PVC laminated galvanized steel sheet, etc

The most commonly used type of coating surface is still hot-dip galvanized plate.

There are three types of surface coatings available, namely ordinary zincification, small zinc flower, and no zinc flower.

As per the current national standard for continuous hot dip galvanized steel sheet and strip (GB/t2518-2008), the nominal thickness of the galvanized sheet ranges from 0.3mm to 5.0mm, the nominal width ranges from 600mm to 2050mm, and the nominal length ranges from 1000mm to 8000mm.
