Typical weight of 5 ft × 5 ft sheet of fine aluminium window screening used to cover homemade radio dish

Weight of a 5 ft × 5 ft sheet of fine aluminium window screening.

Let’s work it out step by step:

1. Typical fine aluminium insect screen:
   • Mesh: about 18 × 16 per inch
   • Wire diameter: ~0.011 inch (0.28 mm)
   • Open area ≈ 60% (so only ~40% metal)
   • Average density: about 0.035 lb/ft² (≈ 0.57 oz/ft² ≈ 0.17 kg/m²)
2. Area of your piece:

5 ft×5 ft=25 ft^2.

3. Weight:

25 ft^2×0.035 lb/ft^2≈0.875 lb.

That’s about 14 ounces (≈ 400 g).

✅ So a 5 ft × 5 ft sheet of fine aluminium window screen weighs roughly 0.9 lb (≈ 0.4 kg).
