We know that aluminum profiles are long and straight, and each section is the same shape. So as long as you know its cross-sectional area, you can calculate its volume. Multiply the volume by the aluminum alloy's density of 2.7g/m3. Therefore, if you want to calculate the weight of the aluminum profile, you must have the aluminum profile section drawing and the length of the profile. Fortunately, it is a CAD drawing, so that no matter how complicated the section is, its area can be quickly calculated.

If you don’t have a drawing, you can also provide samples. If you have a sample, it’s very simple. Just take the weighing and multiply the unit price of the aluminum profile. (Many aluminum profile manufacturers quote by the kilogram or by tonnage. ), the cost of the aluminum profile can be calculated. If it is a deep-processed aluminum profile, if there are many faces or holes drilled on it, the loss of these aluminum profiles should be counted, and some weight should be added to the actual weight.

The theoretical weight is calculated according to the drawing, and there will be a certain error with the actual product, but the error is very small. The actual weighed weight will be more accurate. Some customers who come to inquire can not provide drawings or samples, so they send a photo to ask for the price, which makes our technicians unable to start. Although some customers gave the approximate size of the cross-section, the irregular cross-sectional area still requires detailed drawings to calculate the accurate meter weight.
