Color coated sheet weight

The weight of color coated sheets mainly depends on factors such as substrate material, thickness, coating type, and coating weight. The following is a detailed analysis of the color coated sheet weight:

1. Substrate material and thickness

Color coated steel plates are usually made by surface coating or laminating various organic coatings or chemical coatings such as plastic films on substrates such as galvanized steel plates or aluminum zinc coated steel plates. The thickness of the substrate is one of the key factors affecting the weight of the color coated sheet. The common thickness range of color steel plates is from 0.3 millimeters to 1.2 millimeters, and the thicker the thickness, the heavier the weight per unit area. For example, a 0.3mm thick color steel plate weighs approximately 4 to 5 kilograms per square meter, while a 1.2mm thick color steel plate can weigh over 10 kilograms per square meter.

2. Coating type and coating weight

There are various types of coatings on color coated sheets, including polyester, fluorocarbon, etc. These coatings have a relatively small impact on the weight of the color coated sheet, but may also vary due to differences in coating thickness and density. In addition, the weight of the coating on the color coated sheet will also affect its total weight. The weight of the coating generally fluctuates within a certain range, and the specific value depends on the manufacturer's process standards and customer requirements. The coating weight range of new substrate materials such as high aluminum zinc aluminum magnesium substrates may also vary.

3. Weight calculation formula

The color coated sheet weight can be calculated using the following formula: weight per meter=thickness x width x 7.85 (steel plate density, in g/cm ³, converted to kg/m ² needs to be multiplied by 1000 and then divided by 1000000, but in this formula, it is directly calculated as 7.85, and the result is still in kg, which is a similar calculation). However, this formula is only applicable for calculating the weight of uncoated pure steel plates. For color coated sheets, the actual weight may be slightly greater than this calculated value due to the presence of coatings and plating layers. Therefore, when calculating the weight of color coated sheets, it is usually necessary to refer to the specific parameters of the manufacturer or conduct actual weighing.

4. The impact of weight on usage

The color coated sheet weight has a certain impact on its use. During the architectural design and construction phase, it is necessary to select suitable color coated panels based on the load-bearing capacity of the structure. Although overweight color coated panels provide higher strength, they may also increase the overall burden and construction difficulty of the building. Therefore, when choosing color coated panels, in addition to considering their weight, it is also necessary to comprehensively consider factors such as their strength, corrosion resistance, and decorative properties.
In summary, the weight of color coated sheets is a complex parameter influenced by multiple factors. In practical applications, it is necessary to choose the appropriate type and specification of color coated sheet according to specific needs and conditions.
