How to Calculate Roofing Sheet Weight?

Because the price of our color-coated roofing sheet depends on the weight, calculating the weight is an important step before purchasing roofing sheets. The calculated formula is for your reference.

 Thickness(mm) * Width (mm) * Length(m) * 7.85= Weight (kg/pcs)

Note: The width is the feeding width, as the figure shows, the effective width is 760mm, after corrugation width is 810mm, and the feeding width is 914mm. When calculating the weight, we should use feeding width instead of effect width and after corrugation width.


Colour Coated Roofing Sheet Applications

Because its good performance, corrosion resistance, and long service life, color coated roofing sheets widely used in the roofing of industrial and civil buildings, warehouses, special buildings, long-span steel structure houses

What Affects the Quality of Roofing Sheet?

1. Temperature. High-temperature coating softening, corrosion medium easy to stick. It is easy to penetrate into the substrate, the oxygen content in the water will increase at high temperatures, and the corrosion speed will be accelerated at a certain temperature.

2. Temperature difference between day and night. Large temperature difference is easy to condensation, forming galvanic corrosion conditions on the exposed metal. In addition, the large temperature difference also leads to frequent cold and hot deformation of the coating, which will accelerate the aging and loose coating, and the external corrosive medium is easy to penetrate into the substrate.

3. Ultraviolet light. Ultraviolet light has more destructive power than low-energy spectrum and can also break chemical bonds in substances, causing them to break. Therefore, the duration and intensity of sunlight will affect the stability of the roof panel coating structure in areas with strong UV

4. Rainfall. The high acidity of rainfall is certainly detrimental to corrosion resistance. But the rainfall has a double function, on the wall panel and the slope of the roof panel, the rainfall has the effect of cleaning the surface of the steel plate and washing away the surface corrosion products, but for the low slope of the roof panel and the part of the drainage is not smooth, the rainfall is easy to cause the corrosion intensification.

5. Wind direction and speed. Wind direction and speed act like water, and often go hand in hand. It is a test for material connections, as wind causes them to loosen and rain to seep into the interior of the building.
