To calculate the weight of a galvalume steel coil, you need to know its dimensions (length, width, and thickness) as well as the density of the galvalume steel material. Galvalume is typically a coating of zinc and aluminum applied to steel, so the density of galvalume would be a bit less than that of pure steel.

Here’s the formula to calculate the weight of a steel coil:

Weight=Length×Width×Thickness×DensityWeight=Length×Width×Thickness×Density

Make sure all dimensions are in the same unit (usually meters or millimeters). Density can vary slightly depending on the exact composition of the galvalume coating, but a common value is around 7850 kg/m³ for steel.

So, if you have the length 𝐿L, width 𝑊W, thickness 𝑇T, and density 𝐷D of the galvalume steel, you can plug those values into the formula to find the weight of the coil.

Here’s a step-by-step guide:

1. Measure the length (in meters or millimeters).
2. Measure the width (in meters or millimeters).
3. Measure the thickness (in meters or millimeters).
4. Look up the density of galvalume steel (around 7850 kg/m³ is typical).
5. Plug these values into the formula and calculate the weight.

Keep in mind that this formula gives you the weight of the entire coil. If you’re interested in the weight of a specific length of the coil, you would need to divide the total weight by the total length of the coil and then multiply by the desired length.
