Large-Scale Physical Bird Exclusion

Pestrol Heavy Duty Bird Netting works by creating a physical barrier between birds and the area requiring protection.

Instead of relying on sound, movement, visual deterrents or chemicals, correctly installed netting physically prevents birds from gaining access.

This makes it particularly useful where birds repeatedly:

• Feed on fruit or crops
• Enter warehouses or factories
• Roost in roof structures
• Nest around buildings
• Enter loading and storage areas
• Access commercial growing areas
• Shelter in large covered structures

Once correctly installed, the netting provides continuous exclusion without batteries, electricity, poison or electronic components.

Why Choose the 20m x 20m Size?

The 20m x 20m net provides 400m² of coverage, making it one of the largest options in the Pestrol Heavy Duty Bird Netting range.

The broad square format is particularly practical for installations requiring substantial coverage in both directions.

Ideal applications include:

• Large orchards
• Commercial fruit-growing areas
• Berry enclosures
• Large vegetable-growing areas
• Nurseries
• Commercial courtyards
• Warehouses
• Factories
• Large sheds
• Roof areas
• Loading and storage areas
• Industrial bird-exclusion systems

Where the installation area suits its dimensions, one 20m x 20m sheet can help reduce the number of joins required compared with installing multiple smaller nets.

Fine 19mm x 19mm Square Mesh

The netting features a:

19mm x 19mm square mesh

The fine mesh creates a consistent physical barrier suitable for bird-exclusion applications where larger openings may not provide the required protection.

Because the mesh is square rather than diamond shaped, the dimensions remain consistent in both directions.

This helps make the netting easier to:

• Measure accurately
• Position
• Align
• Tension
• Cut
• Incorporate into permanent bird-proofing systems

Square Mesh for More Precise Installation

Square mesh becomes especially valuable when installing a large 20m x 20m sheet.

Netting that pulls disproportionately in one direction can become increasingly difficult to align as the installation area grows.

The Pestrol Heavy Duty netting is designed to resist this distortion, helping maintain consistent dimensions across the installation.

This can contribute to:

• More accurate positioning
• Consistent tension
• Cleaner edges
• Reduced distortion
• Easier measuring
• Faster professional installation

For large commercial and industrial projects, these characteristics can help reduce unnecessary installation time and labour.

Heavy-Duty 68GSM Construction

The netting weighs 68 grams per square metre and is manufactured using 600 Denier / 6-ply HDPE.

Six strands of UV-treated polyethylene twine are twisted and knotted to provide a combination of strength, durability and relatively low overall weight.

The mesh is also pressure stretched and tightened during manufacture to help produce a stable finished net.

UV Stabilised for Permanent Outdoor Use

Large bird-proofing installations are often intended to remain in place throughout the year.

This means the material may be continuously exposed to:

• UV radiation
• Strong sunlight
• Rain
• Wind
• Heat
• Cold
• Seasonal weather changes

The HDPE netting is UV stabilised for long-term outdoor installation.

The manufacturer provides a 10-year guarantee against manufacturing defects and defects caused by UV breakdown.

Correct installation, support and tensioning remain important to the overall lifespan of the completed system.

Low-Visibility Black Finish

With a net covering up to 400m², keeping the installation visually discreet can be particularly important.

The combination of:

• Black HDPE
• Fine 1mm twine
• 19mm mesh

helps create a low-visibility barrier that becomes considerably less noticeable when viewed from a distance.

This makes the netting suitable for both functional commercial installations and areas where maintaining the appearance of the property is important.

Does Not Absorb Water

HDPE does not absorb water.

As a result, the netting does not become waterlogged simply because it is exposed to wet weather.

The material is also:

• Rot-proof
• Non-conductive
• Stable in sub-zero temperatures

These properties make it particularly well suited to permanent outdoor and exposed installations.

Orchard & Commercial Crop Protection

With 400m² of coverage, the 20m x 20m size is particularly well suited to larger horticultural installations.

It can form part of a properly supported enclosure around:

• Orchard sections
• Fruit trees
• Berry crops
• Vegetable crops
• Commercial growing areas
• Nurseries
• Other bird-sensitive crops

Physical exclusion helps prevent birds from reaching ripening fruit and other protected produce.

For permanent installations, the netting should be properly supported and tensioned rather than loosely draped over trees or plants.

Warehouse & Factory Bird Control

Large warehouses and factories can provide birds with numerous protected areas for roosting and nesting.

Bird activity can occur around:

• Rafters
• Roof structures
• Storage areas
• Loading zones
• Building services
• Machinery
• Elevated ledges

Heavy Duty Bird Netting can be used to physically prevent access to selected areas while maintaining airflow and visibility.

The 20m x 20m sheet provides 400m² of continuous material, making it particularly useful for substantial commercial installations.

Loading Docks & Large Commercial Areas

Birds can frequently enter large covered loading and storage areas because these spaces remain open during normal business operations.

The netting can form part of an appropriately designed exclusion system around:

• Loading docks
• Commercial courtyards
• Covered work areas
• Storage zones
• Building voids
• Roof spaces
• Plant and equipment areas

The objective is to prevent birds accessing problem areas without unnecessarily interfering with the normal use of the building.

Suitable for Permanent Orchard Structures

The combination of 68GSM material, 6-ply HDPE construction and UV stabilisation makes the netting suitable for appropriately designed permanent orchard and horticultural structures.

Its 20m x 20m dimensions are particularly useful for broad growing areas where a large square sheet provides more efficient coverage than several smaller nets.

Suitable for Zipper Access

The stable square mesh allows appropriately designed zipper access points to be incorporated into professional installations.

Zipper access can be useful where technicians need to reach:

• Lighting
• Electrical equipment
• Building services
• Machinery
• Maintenance areas

The zipper should be professionally integrated so the bird-exclusion barrier remains complete when the access point is closed.

Rope Marker Ties for Easier Setup

The netting includes rope marker ties at the corners.

These help installers identify the corners and establish the correct orientation while unpacking and positioning the net.

This feature is particularly useful with a large 20m x 20m sheet, where locating and organising each corner before tensioning can make installation considerably easier.

Installation Considerations

Large-scale bird netting requires careful planning.

Before installation:

1. Measure the entire area requiring protection.
2. Identify all bird entry points.
3. Plan the support structure and fixing system.
4. Determine how the 20m x 20m sheet will be positioned.
5. Plan perimeter fixing points.
6. Identify corners, penetrations and obstacles.
7. Determine whether maintenance access is required.
8. Position and tension the net appropriately.
9. Inspect the completed installation for openings.

Particular attention should be given to:

• Perimeter edges
• Corners
• Joins
• Roof penetrations
• Pipes and services
• Structural connections

Even a small unprotected opening can compromise an otherwise complete exclusion system.

Correct Tension Is Essential

A large bird net should be appropriately supported and tensioned.

Correct tension helps:

• Maintain the square mesh
• Reduce sagging
• Keep netting clear of equipment
• Produce a cleaner finished installation
• Maintain effective bird exclusion
• Reduce potential wildlife-entanglement hazards

For a 400m² net, professional installation may be appropriate, particularly for elevated, commercial or complex installations.
