Logic Used: Weight = Volume of Wire × Density.
Volume is calculated based on total length of warp and weft wires required to cover the area, considering a geometric crimp factor of ~3%.

What is a Steel Wire Mesh Weight Calculator?
A steel wire mesh weight calculator is an essential engineering tool designed to determine the theoretical mass of woven wire cloth, screens, or welded mesh sheets. It is widely used by civil engineers, construction managers, and procurement specialists to estimate shipping loads, structural requirements, and material costs.
Unlike generic metal weight calculators, this tool specifically accounts for the unique geometry of mesh—defined by wire diameter, aperture (opening size), and the pitch (center-to-center distance). Whether you are using Carbon Steel, Stainless Steel 304, or Aluminum, calculating the exact weight is crucial for logistics and structural integrity verification.
Common misconceptions include assuming mesh weight is purely based on sheet volume. In reality, the "open area" (the empty space between wires) significantly reduces the overall weight compared to a solid sheet of the same thickness.
Steel Wire Mesh Weight Calculator Formula
The calculation relies on determining the total volume of wire used in the warp (longitudinal) and weft (transverse) directions and multiplying it by the material density.

Practical Examples
Example 1: Heavy Duty Screening
A mining company needs to order Stainless Steel 304 mesh for a shaker screen.
Material: SS 304 (Density 7900 kg/m³)
Wire Diameter: 2.0 mm
Aperture: 10.0 mm
Roll Size: 2m wide x 20m long
Using the steel wire mesh weight calculator, we find the weight is approximately 2.06 kg/m². For a 40m² roll, the total shipping weight is roughly 82.4 kg. This helps the logistics team plan for pallet limits.
Example 2: Security Fencing
A contractor is installing a security fence using thick Carbon Steel wire.
Material: Carbon Steel (7850 kg/m³)
Wire Diameter: 4.0 mm
Aperture: 50.0 mm
Roll Size: 2.5m wide x 100m long
The calculator indicates a weight of roughly 1.82 kg/m². The total project requires 250m² of mesh, resulting in a total load of 455 kg.
How to Use This Steel Wire Mesh Weight Calculator

Key Factors That Affect Mesh Weight Results
Several physical and economic factors influence the final calculation:
Wire Diameter vs. Aperture Ratio: As the wire gets thicker relative to the opening, the weight increases exponentially because the volume of steel per square meter rises.
Material Density: Switching from Aluminum to Copper triples the weight for the exact same mesh geometry due to density differences (2700 vs 8960 kg/m³).
Crimp Factor: Woven wires are not straight; they undulate over and under each other. This adds 1-5% extra length to the wire compared to the flat sheet dimensions, increasing actual weight.
Weave Type: While this calculator assumes a standard square weave, Dutch weaves or twilled weaves pack wires tighter, significantly increasing weight per area.
Manufacturing Tolerances: Industrial standards allow for small deviations in wire diameter. A +0.05mm tolerance on a fine wire can alter total weight by 5-10%.
Coating and Galvanization: If the steel is galvanized, the zinc coating adds mass. Standard weight calculators typically compute the bare metal weight unless a coating factor is added.
Frequently Asked Questions (FAQ)
Q1: Does this calculator include the weight of packaging?
No, the result is the net theoretical weight of the mesh itself. Pallets, cores, and wrapping materials are extra.
Q2: How accurate is the mesh count estimation?
The mesh count (wires per inch) is mathematically derived from the diameter and aperture. It is a theoretical approximation useful for classification.
Q3: Can I calculate for welded mesh?
Yes, the logic for total wire volume applies to both woven and welded mesh, though welded mesh lacks the "crimp factor," so the actual weight might be slightly lighter (~3%) than calculated here.
Q4: Why is Open Area percentage important?
Open Area determines flow rate (for filtration) and transparency (for screens). A high open area means less material and lighter weight.
Q5: What is the density of 316 vs 304 stainless steel?
SS 316 is slightly denser (~7980 kg/m³) than SS 304 (~7900 kg/m³) due to the addition of Molybdenum.
Q6: How do I convert the result to pounds (lbs)?
1 kg equals approximately 2.20462 lbs. Multiply the result in kg by 2.205 for an estimate in pounds.
Q7: Does wire gauge affect the calculation?
Yes, "Gauge" is just another way to state diameter. You must convert Gauge to millimeters before using this tool.
Q8: Is this tool suitable for perforated metal?
No. Perforated metal is a solid sheet with holes punched out. This calculator assumes a grid of wires. The formulas are completely different.

// Crimp Factor: Woven wire travels a longer path than the straight line.
