Are you tired of dealing with corroded steel plates that require constant upkeep? Look no further than galvanized sheet!
This cost-effective solution involves coating steel plates with a layer of zinc to prevent corrosion and extend their lifespan.
With approximately half of the world’s zinc production being used for galvanizing, this method has proven to be widely effective.
There are various types of galvanized sheets available, including hot-dip, electro, and alloyed steel sheets, among others.
The most commonly used type is still hot-dip galvanized plate, which can have either ordinary zincification, small zinc flower, or no zinc flower coatings.
The nominal thickness of galvanized sheets ranges from 0.3mm to 5.0mm, and they are typically delivered based on their theoretical weight.
Theoretical weight takes into account the weight of the cold-rolled or hot-rolled steel plate and the galvanized layer.
With the help of our galvanized sheet weight calculator, you can easily determine the weight of your galvanized sheet.
Say goodbye to corroded steel plates and hello to long-lasting galvanized sheets!
What is the 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.
Galvanized sheet weight calculator
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.

Nominal coating weight range
Coating form | Applicable coating surface structure | Nominal coating weight range (g/m2) | |
---|---|---|---|
Pure zinc coating (Z) | Zinc iron alloy coating (ZF) | ||
Equal thickness coating | N, M, F, R | 50~600 | 60~180 |
Differential coating | N, M, F | 25 ~ 150 (each side) | — |
Note:
- N, M and F are pure zinc coatings.
- N indicates that the surface structure of the coating is ordinary zinc flower.
- M indicates small zinc flower;
- F indicates no zinc flower;
- R is the common zinc flower of zinc-iron alloy coating.
