How to accurately calculate the unit weight of C-section steel (including C-section purlins)?

To accurately calculate the unit weight of C-channel steel, including C purlins, you first need to understand the basic calculation formulas. The main points are summarized below:

The weight of C-channel steel can be calculated using the dimensions of its expanded section, thickness, and material density. The specific formula is: Weight of C channel steel = (Sum of expanded section dimensions + Thickness) * 100 * 0.00785 = kg/m. Here, “expanded section dimensions” refers to the width and height, while “Thickness” refers to the thickness of the C-channel steel. All of these dimensions must be in centimeters.

Another method involves adding up the dimensions of the expanded section of C-channel steel, multiplying by the thickness and then by the density (7.85). This method also applies to calculating the weight of C purlins.

For C purlins, the weight calculation formula is: Length × Width × Thickness × Density = Weight of the purlin. This indicates that, in addition to considering the basic parameters of C-channel steel, the specific length of the purlin must also be taken into consideration.

The theoretical weight of steel can also be calculated based on the steel's density, cross-sectional area and length, where the density of steel is generally expressed in kilograms per cubic meter (kg/m³).

To accurately calculate the unit weight of C channel steel including C purlins, it is necessary to use the formulas mentioned above based on its specific dimensions (including width, height and thickness) as well as the density of the material (generally 7.85 or 7.86 kg/m³). For C purlins, the effect of length on weight must also be considered. In practice, you can choose the appropriate calculation method based on specific design drawings and specifications.

What is the density of C section steel (especially C purlins)?

The density of C section steel (especially C purlins) is 7.85kg/m³. This value applies to the general density of steel, including C-section steel and C purlins. There is no direct evidence in the data that the density of C purlins differs significantly from that of other types of steel or materials. Therefore, it can be assumed that the density of the C purlins is the same as the C section steel, which is 7.85kg/m³.

How significant is the difference in weight of C purlins in different materials?

The weight variation of C purlins under different materials is mainly reflected in their specifications and thickness. The actual weight of a C purlin can be calculated through the product of its width, thickness and 0.00785.

This indicates that with the change in the width and thickness of the C core, its actual weight will also vary. Furthermore, C purlins of different specifications but the same thickness have a considerable difference in weight per meter, and the greater the difference in specification data, the greater the difference in weight per meter.

This implies that in addition to the material (such as galvanized or non-galvanized) possibly impacting the weight, the specific specifications of the C purlin (such as its height) also play a significant role in determining its weight difference.
