Question 1

How is hexagonal wire mesh weight calculated?

Accepted Answer

Hexagonal wire mesh weight per m² is calculated using: kg/m² = 2.04 × d² × ρ ÷ (M + d), where d is wire diameter in mm, M is mesh opening in mm (flat-to-flat internal distance of the hexagon), and ρ is material density in g/cm³. The factor 2.04 accounts for the three-directional wire geometry of a regular hexagonal pattern plus the twisted joint overlap. For galvanized steel (ρ = 7.85 g/cm³), a 25 mm mesh with 0.9 mm wire gives approximately 0.50 kg/m².

Question 2

What are the standard sizes for chicken wire (hexagonal wire mesh)?

Accepted Answer

Standard hexagonal wire mesh mesh sizes are 13 mm, 19 mm, 25 mm, 38 mm, 50 mm, and 75 mm (flat-to-flat opening). Wire diameters range from 0.56 mm (26 gauge) to 1.65 mm (16 gauge). The most common size for poultry netting is 25 mm × 0.9 mm (20 gauge). Gabion boxes use 60–80 mm mesh with 2.0–2.7 mm wire.

Question 3

What is the difference between chicken wire and hexagonal wire mesh?

Accepted Answer

Chicken wire is a colloquial name for hexagonal wire netting (also called hex netting or poultry netting). Both refer to the same product: a lightweight mesh of galvanized wire woven into a hexagonal (six-sided) pattern. For heavier applications like gabion cages and erosion control, the same hexagonal weave uses thicker wire and is called gabion mesh or reno mattress mesh.

Question 4

How much does a roll of chicken wire weigh?

Accepted Answer

A standard 1 m × 50 m roll of 25 mm hexagonal wire mesh (chicken wire) with 0.9 mm galvanized wire weighs approximately 25 kg. Roll weight = kg/m² × roll width × roll length. Always confirm with the factory before booking freight, as actual weight depends on wire gauge tolerance and coating weight.

Mesh (mm)	Wire (mm)	Gauge (SWG)	kg/m²	Typical use
13	0.56	24	0.30	Garden netting, pest control
19	0.71	22	0.38	Small animal enclosures
25	0.9	20	0.50	Poultry netting, garden fencing
25	1.0	19	0.61	Rabbit fencing, reinforcing
38	1.2	18	0.66	Light gabion, slope protection
50	1.4	17	0.61	Gabion, erosion control
75	2.0	14	0.83	Heavy gabion, rip-rap containment
