Calculating the weight of C-channel steel, including C-purlins, is essential for various construction and engineering projects. This guide provides a comprehensive method to accurately determine the weight based on specific dimensions and material density.

C Channel Weight Calculator

To calculate the weight of a C-channel, you need to know the dimensions of the channel, its thickness, length, and the number of pieces. The formula for calculating the weight is:

Weight kg =(Sum of the dimensions of the expanded section+Thickness)×100×0.00785

Where:

  • Dimensions of the expanded section include the width and height.
  • Thickness is the thickness of the C-channel steel.
  • All dimensions must be in centimeters.

To calculate the weight, you need to input the following dimensions:

  • Side (A, mm)
  • Side (B, mm)
  • Side (C, mm)
  • Thickness (t, mm)
  • Length (m)
  • Pieces

Output Field

  • Weight (Kg): This field will display the calculated weight.

C-Purlin Weight Calculator

For C-purlins, the weight calculation formula is slightly different:

Weight kg =Length×Width×Thickness×Density

Where:

  • Length, width, and thickness are the dimensions of the C-purlin.
  • Density is typically 7.85 kg/m³ for steel.

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 key points are summarized below:

The weight of C-channel steel can be calculated using the dimensions of its expanded section, thickness, and the density of the material.

The specific formula is:

Weight of C-channel steel = (Sum of the dimensions of the expanded section + Thickness) * 100 * 0.00785 = kg/m.

Here, “dimensions of the expanded section” refer to the width and height, while “Thickness” refers to the thickness of the C-channel steel. All these dimensions must be in centimeters.

Another method involves adding the dimensions of the C-channel steel’s expanded section, multiplying by the thickness, and then by the density (7.85). This method also applies to the calculation of 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 the C-channel steel, the specific length of the purlin must also be taken into account.

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

To accurately calculate the unit weight of C-channel steel, including C-purlins, it’s necessary to use the formulas mentioned above based on their specific dimensions (including width, height, and thickness), as well as the density of the material (usually 7.85 or 7.86 kg/m³). For C-purlins, the effect of the length on the 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 C purlins is the same as that of C-section steel, which is 7.85kg/m³.

How Significant Is the Weight Difference of C-Purlins Under Different Materials?

The weight variation of C-purlins under different materials primarily reflects 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 width and thickness of the C-purlin, its actual weight will also vary. In addition, 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 larger their weight per meter difference.

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