To determine the weight of color-coated steel per square meter (m2), the weight can be calculated based on the sheet&#;s area and its thickness. The general formula to calculate the weight of color-coated steel per area is as follows:

Weight (kg) = Area (m2) × Thickness (mm) × Density of Color Coated Steel (kg/m2/mm)

The density of color-coated steel (kg/m2/mm) is usually provided by the manufacturer or can be found in the technical documentation of color coated steel.

For example, if we have a color-coated steel sheet with an area of 1m2 and a thickness of 0.5mm, and the density is 7.85 kg/m2/mm, then the weight of the sheet will be:

Weight = 1m2 × 0.5mm × 7.85 kg/m2/mm = 3.925 kg

Calculating the Number of Sheets Based on Weight

Sometimes, users may need to calculate the number of color-coated steel sheets based on the specific weight (kg) they want to use. To calculate the number of sheets based on weight, use the following formula:

Number of Sheets = Weight (kg) ÷ Thickness (mm) ÷ Area (m2)

For example, if a user wants to purchase 100kg of color-coated steel with a thickness of 0.4mm, and the density of color-coated steel is 7.85 kg/m2/mm, then the number of sheets needed will be:

Number of Sheets = 100kg ÷ 0.4mm ÷ 7.85 kg/m2/mm &#; 32 sheets

Note that in the calculation process, it is necessary to take the integer part of the result to round up the number of color-coated steel sheets to be purchased.

Color-coated steel is an excellent choice for construction projects, meeting various requirements for sustainability and high applicability.
