Earthing Strip Weight Chart

An earthing strip weight chart helps estimate the weight of metal strips based on their size, thickness and length. The actual weight can vary depending on the material grade, density and surface coating.

For GI earthing strips, the most commonly required information is the strip size and corresponding weight per metre. The calculation should be based on the confirmed material specification and applicable material density.

GI Earthing Strip Weight Chart

GI earthing strip weight depends mainly on the strip width, thickness, length and material density. The zinc coating can also contribute to the finished weight.

A typical chart can be arranged by strip size and weight per metre:

The exact weight should be verified against the material grade and calculation method used for the GI strip.

Example: Calculating GI Earthing Strip Weight

For a 25 × 5 mm GI strip with a length of 1 metre:

Width = 25 mm
Thickness = 5 mm
Length = 1 m

First convert the dimensions into metres:

25 mm = 0.025 m
5 mm = 0.005 m

Then:

Weight = Width × Thickness × Length × Material Density
Weight = 0.025 × 0.005 × 1 × Material Density

The final weight depends on the confirmed density used for the GI material.

GI Flat Weight Chart

The weight of a GI flat is determined by its width, thickness, length and material density. For coated material, the surface coating may also affect the final weight.

A GI flat weight chart is useful when estimating material requirements for earthing, fabrication, structural applications and other projects where strip dimensions are specified.

When comparing weights, make sure the dimensions are given in the same units and that the calculation uses the appropriate material density.

Example: Calculating GI Flat Weight

For a 40 × 5 mm GI flat with a length of 10 metres:

Width = 40 mm = 0.040 m
Thickness = 5 mm = 0.005 m
Length = 10 m

Weight = 0.040 × 0.005 × 10 × Material Density

The resulting value represents the theoretical material weight based on the confirmed material density. The actual supplied weight should be checked against the product specification.

Strip Coil Weight Chart

Strip coil weight depends on the strip width, thickness, coil length and material density. When the strip length is known, the approximate coil weight can be calculated using these dimensions.

Strip Coil Weight = Strip Width × Strip Thickness × Coil Length × Material Density

For a coil where the strip length is not available, the coil dimensions, including the inner and outer diameter, can be used to estimate the strip length and calculate the approximate coil weight.

The final coil weight may vary depending on the material and actual coil dimensions.

Example: Calculating Strip Coil Weight

Consider a strip coil with:

Width = 100 mm = 0.100 m
Thickness = 2 mm = 0.002 m
Coil Length = 1,000 m

The calculation is:

Weight = 0.100 × 0.002 × 1,000 × Material Density

The final coil weight is obtained by applying the confirmed material density to the calculated strip volume.

How to Calculate Strip Weight Per Meter

Strip weight per metre can be calculated from the strip width, thickness and material density.

Weight per Meter = Width × Thickness × Material Density

The units must be kept consistent throughout the calculation. If the strip dimensions are provided in millimetres, convert them appropriately before applying the material density.

Strip Weight Chart by Size and Thickness

Strip weight changes with both size and thickness. A wider or thicker strip contains more material and therefore has a higher weight for the same length.

Example: Comparing Strip Sizes

Consider two strips with the same material density and a length of 1 metre:

25 × 5 mm strip
Weight = 0.025 × 0.005 × 1 × Material Density

50 × 6 mm strip
Weight = 0.050 × 0.006 × 1 × Material Density

The second strip has a larger cross-sectional area, so its calculated weight per metre will be higher when the same material density is used.

The sizes below, such as 2000 × 1000 × 2.0 mm, 2500 × 1250 × 2.5 mm and 3000 × 1500 × 3.0 mm, are sheet and plate formats rather than conventional strip dimensions, so they are listed separately from the GI earthing-strip and strip-coil data.

Factors Affecting Strip Weight

Several factors determine the final weight of a strip:

• Strip width: A wider strip contains more material and weighs more per metre when thickness and material remain the same.
• Strip thickness: Increasing thickness increases the weight per metre for a given width.
• Strip length: Total weight increases as the strip length increases.
• Material grade and density: Different materials have different densities, which directly affects calculated weight.
• Surface coating: Zinc and other coatings can contribute to the finished weight of the strip.
• Coil dimensions: Coil width, thickness, inner diameter and outer diameter can be used to estimate coil length and overall coil weight.

Using the correct dimensions and material density is important when calculating strip weight for purchasing, fabrication, transportation and project estimation.

Example: Calculating Strip Weight Per Meter

For a 50 × 6 mm strip:

Width = 50 mm = 0.050 m
Thickness = 6 mm = 0.006 m
Length = 1 m

Therefore:

Weight per Meter = 0.050 × 0.006 × Material Density

The resulting value gives the theoretical weight per metre based on the confirmed material density.

For procurement and fabrication calculations, use the density specified for the actual material rather than applying an unverified generic value.
