As an integrated manufacturer and exporter with our own factory, Pauleen has been producing hexagonal woven wire mesh for more than ten years. This guide explains how to select the right specification for your project.
1. Start with the Application and Service Environment
Before selecting wire diameter, mesh opening, or material, define the actual working conditions:
Mechanical load: Will the mesh bear static loads, impact, abrasion, or animal pressure?
Corrosion environment: Indoor dry, rural, industrial, coastal, marine, or chemical?
Aperture requirement: Must the mesh contain small animals, support plaster, retain stones, or allow drainage?
Service life: Temporary, short-term, or long-term structural use?
Installation method: Rolls, panels, gabion boxes, mattresses, or custom cut pieces?
Applicable standard: ASTM, EN, ISO, or project-specific specification?
These factors determine whether you need a light, flexible poultry netting or a heavy, double-twist gabion mesh.
2. Material Selection
The base material controls strength, corrosion resistance, and cost.
Low Carbon Steel Wire
Common grades include Q195, Q235, SAE1006, and SAE1008. Low carbon steel offers good ductility and is widely used for galvanized or PVC-coated hexagonal mesh. It is suitable for general fencing, poultry netting, and plaster reinforcement when properly coated.
Electro-Galvanized Wire
Electro-galvanized wire has a thin zinc coating, typically 10–25 g/m². It provides moderate corrosion resistance for indoor or dry applications. It is economical but not recommended for long-term outdoor or humid environments.
Hot-Dip Galvanized Wire
Hot-dip galvanized wire has a much thicker zinc coating, usually 40–300 g/m², depending on the standard and requirement. It can be galvanized before weaving or after weaving. Hot-dip galvanized after weaving provides excellent protection at cut edges and is preferred for outdoor fencing, gabions, and marine-adjacent projects.
Zn-Al Alloy Coated Wire (Galfan)
Galfan wire, typically Zn-5%Al mischmetal, offers superior corrosion resistance compared with conventional galvanized wire. It is an excellent choice for coastal, industrial, and long-life gabion applications.
Stainless Steel Wire
Stainless steel grades such as 304, 304L, 316, and 316L are used for high-corrosion, chemical, marine, and architectural applications. Grade 316/316L contains molybdenum and provides better resistance to chlorides and aggressive environments. For high-temperature applications, grades such as 310S may be considered.
PVC or PE Coated Wire
PVC-coated hexagonal mesh uses a galvanized core wire covered with a UV-stabilized PVC or PE layer. The coating thickness is commonly 0.4–1.0 mm and can be supplied in green, black, gray, or other colors. It combines corrosion resistance with an attractive appearance and is widely used for garden fencing and animal control.
Copper, Brass, and Architectural Alloys
For decorative or architectural applications, copper, brass, and other alloys can be woven into hexagonal mesh. These materials are selected mainly for aesthetics and specialized corrosion performance.
3. Wire Diameter Selection
Wire diameter is one of the most important factors affecting strength, weight, flexibility, and cost. In hexagonal woven wire mesh, the wire diameter is usually specified as the bare wire diameter before coating. For PVC-coated mesh, both the core wire diameter and the final outside diameter should be confirmed.
Typical wire diameter ranges include:
0.4–0.8 mm: Fine mesh for light-duty poultry, insulation, and decorative applications.
0.8–1.2 mm: General poultry netting, garden fencing, and plaster reinforcement.
1.2–2.0 mm: Medium-duty fencing, animal enclosures, and general agricultural use.
2.0–4.0 mm: Heavy-duty gabion mesh, revetment mattresses, and engineering applications.
A larger wire diameter increases tensile strength, stiffness, abrasion resistance, and load-bearing capacity. A smaller wire diameter improves flexibility, reduces weight, and lowers material cost. Larger mesh openings generally require a thicker wire to maintain hexagonal shape and resist deformation. Smaller mesh openings may use thinner wire, but the total wire consumption per square meter can still be high.
A common rule is: if the mesh will be exposed to impact, stone fill, or heavy animal pressure, increase the wire diameter. If flexibility and low weight are more important, reduce the wire diameter while maintaining adequate tensile strength.
4. Mesh Opening Selection
Mesh opening, also called aperture, is the nominal distance between opposite sides of the hexagonal opening. Unless otherwise specified, hexagonal wire mesh openings are often measured across the flats of the hexagon.
Common mesh openings include:
1/2" (13 mm): Plaster reinforcement, small animal control, fine containment.
3/4" (19 mm): Poultry netting, light fencing, plaster backing.
1" (25 mm): General poultry and garden fencing.
1.5" (40 mm): Larger animal enclosures and agricultural fencing.
2" (50 mm): General-purpose fencing and light gabion work.
3"–4" (75–100 mm): Light gabion and erosion control.
60 × 80 mm, 80 × 100 mm, 100 × 120 mm, 120 × 150 mm: Standard double-twist gabion mesh openings.
Smaller openings provide better containment, higher plaster key, and greater surface coverage, but they increase weight and reduce visibility and drainage. Larger openings reduce weight and cost, improve drainage and visibility, but provide less containment and require thicker wire for structural stability.
For gabion and revetment work, the mesh opening is usually selected according to the stone grading. A common recommendation is that the nominal opening should be smaller than the smallest stone size to ensure proper retention.
5. Weave Type and Edge Configuration
Hexagonal woven wire mesh is produced in several weave patterns:
Straight twist: Simple twist, often used for light-duty applications.
Reverse twist: Common for poultry netting and general fencing.
Double twist: The preferred construction for gabions and engineering applications because it provides high mechanical stability and prevents unraveling if a wire breaks.
Edge configurations also matter. Options include twisted edge, wrapped edge, reinforced edge, and galvanized edge wire. For gabion boxes, the selvage and edge wire must be strong enough to withstand filling and installation stresses.
6. Surface Treatment and Corrosion Protection
The correct coating system extends service life significantly.
Electro-galvanized mesh offers a thin coating and is suitable for indoor use at low cost. Hot-dip galvanized before weaving provides good general protection, but cut edges may be exposed. Hot-dip galvanized after weaving provides a thicker coating and better edge protection, making it suitable for outdoor and gabion use. Galfan, or Zn-5%Al, offers excellent corrosion resistance for coastal and industrial environments. PVC or PE coating adds an additional barrier and color options. Stainless steel requires no coating for many corrosive environments.
When specifying coating, state the zinc coating mass in g/m² and the applicable standard, such as ASTM A641, ASTM A975, EN 10223-2, or EN 10223-3. For gabion mesh, ASTM A975 and EN 10223-3 are commonly referenced.
7. Practical Selection Guide by Application
For poultry netting, the usual choice is electro-galvanized or hot-dip galvanized low carbon steel with a wire diameter of approximately 0.6–1.0 mm and a mesh opening of 1/2" to 2". The mesh should be light, flexible, and economical.
For garden fencing, hot-dip galvanized or PVC-coated wire is preferred. A wire diameter of 1.0–1.6 mm and a mesh opening of 1" to 2" provide a good balance of strength and appearance. UV-stabilized PVC is recommended for outdoor use.
For plaster reinforcement, galvanized low carbon steel with a wire diameter of 0.5–1.0 mm and a mesh opening of 1/2" to 3/4" is commonly used. The mesh must provide a good key for plaster or mortar while offering adequate corrosion resistance.
For animal enclosures, hot-dip galvanized or PVC-coated wire with a diameter of 1.2–2.0 mm and a mesh opening of 1" to 2" is suitable. Higher strength and rigidity are important to withstand animal pressure.
For gabion mesh, hot-dip galvanized, Galfan, or PVC-coated wire is typical. Wire diameters usually range from 2.0–4.0 mm, with mesh openings from 60 × 80 mm to 100 × 120 mm. Double-twist construction and high tensile strength are essential.
For marine or chemical applications, stainless steel 304 or 316 is often required. Wire diameters can range from 0.5–3.0 mm, with custom mesh openings depending on the filtration or containment requirement. Grade 316 is preferred where chlorides are present.
For architectural applications, stainless steel, brass, or copper may be used. Wire diameters typically range from 0.5–2.0 mm, with mesh openings from 10–50 mm. The selection is driven by aesthetics, durability, and design intent.
