Galvanized sheet weight calculator (online and free)

April 25, 2024 Roberto Magalhães

The weight of a galvanized sheet can be calculated by its density and dimensions. The density of galvanized sheets is generally considered to be 7.85 tons/cubic meter (or 7.85g/cm³). This density value is applicable to galvanized sheets of different thicknesses.

For example, a 1.0 mm thick galvanized sheet weighs 7.85 kg per square meter, while a 0.75 mm thick sheet weighs 5.8875 kg per square meter.

The specific weight calculation formula is: Theoretical weight of the galvanized sheet = Length of the galvanized sheet x Width of the galvanized sheet x Thickness of the galvanized sheet x Density of the galvanized sheet.

For example, if there is a galvanized sheet with a thickness of 0.2 mm, a width of 1000 mm and a length of 1000 mm, its weight can be calculated by substituting these values in the above formula. For such dimensions and thickness, the density of the galvanized roll is 7.58x1000kg/cubic meter, therefore the weight of a steel plate 1 meter long, 1 meter wide and 0.2mm thick is: 0.21, 01.0*7.85=1.57kg .

It is important to note that the weight of the galvanized sheet can also be affected by the galvanization layer, since galvanized sheets are processed by galvanizing based on cold-rolled or hot-rolled steel sheets.

In addition, the specification table and theoretical knowledge of the weight of galvanized sheets also show that the nominal thickness range of galvanized sheets is 0.3mm ~ 5.0mm, the nominal width is 600mm ~ 2050mm and the nominal length is 1,000mm ~ 8,000mm, which further illustrates the complexity and diversity in calculating the weight of galvanized sheets.

Galvanized Sheet Weight Calculator

Galvanized sheets are typically delivered based on their theoretical weight, while 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 or hot rolled steel sheet on which they are based. This weight includes two parts:

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

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

Generally, the thicker the galvanized sheet, the greater the allowable error range, rather than a fixed value of 0.02-0.04 millimeters. Thickness deviation also varies depending on factors such as yield strength and traction coefficient. This implies that galvanized sheets of different thicknesses will have noticeable weight differences, especially in the case of thicker galvanized sheets.

What is galvanized sheet metal?

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 used in this process to prevent corrosion on the surface of steel plates and extend their useful life.

Types of galvanized sheet?

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

hot galvanized steel sheet
bonded galvanized steel sheet
electrogalvanized steel sheet
one-sided galvanized steel sheet
double sided differential galvanized steel sheet
alloy and composite galvanized steel sheet
colored galvanized steel sheet
printing on coated galvanized steel sheet
PVC laminated galvanized steel sheet, etc.

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

There are three types of surface coatings available: common zinc plating, small zinc bloom and no zinc bloom.

According to the current national standard for continuous hot-dip galvanized steel sheet and strip (GB/t2518-2008), the nominal thickness of 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.

How to accurately measure the real weight of a galvanized sheet?

To accurately measure the actual weight of a galvanized sheet, you first need to understand the density and thickness of the galvanized sheet. The density of a galvanized sheet is normally 7.85g/cm³. The following are several methods to measure the weight of galvanized sheet.

Weighing method: This is a direct method that calculates the weight of the galvanized layer through the difference in weight before and after weighing the galvanized sheet. This method is simple and direct, being suitable for situations recommended in product standards.

X-ray Fluorescence Spectrometry: This method determines the weight of the galvanized layer by analyzing the intensity of zinc radiation in the coating layer of the sample. First, a set of standard plates is made and a relationship curve is established between the intensity of zinc X-rays and the weight of the coating. Then, the intensity of zinc radiation in the sample is measured by regression.

Coulometric Analysis: This is a method described in the ASTM A90/A90M-13 standard for measuring the weight of galvanized steel and galvanized alloy products.

Weighing method by removing the galvanized layer: Using pickling solution to dissolve the zinc on the surface and weighing the weight of the sample before and after pickling, the thickness of the coating is calculated according to the density of zinc (7.2g/cm³ ). This method is suitable for situations where the galvanized layer needs to be removed to assess its thickness.

The method to be chosen depends on the specific testing requirements and the condition of the available equipment. In actual operation, it may be necessary to combine multiple methods to ensure the accuracy of measurement results.
