Rodent-Resistant Grain Containment Panels

Reduce ground-level rodent access with durable, CNC-machined GPO3 panel systems.

Rodent-Resistant Panels

Reduce Ground-Level Rodent Access in Grain Storage

GPO3 panels can be used in grain containment systems where traditional materials fail due to chewing, moisture, or structural weakness. Panels are CNC machined to suit customer-supplied layouts, drawings, and application requirements.

• Hard, durable surface that is difficult for rodents to chew
• Helps reduce gaps at ground level where rodents commonly enter
• Suitable for rigid containment and barrier-style panel systems
• CNC machined for fixing holes, cut-outs, and custom shapes
• Used in agricultural, grain handling, and bulk storage environments

Supply & Design Information

Panel layouts, thickness selection, and system design are typically determined by the customer or their engineer. We manufacture and machine panels to suit your specifications.

While red GPO3 panels are the most commonly supplied option, white GPO3 panels are also available in additional thicknesses subject to supplier availability. Contact us if your project requires white panels for visibility, site matching, or application-specific requirements.

How It Works

GPO3 rodent-resistant panel barrier between grain storage area and outside mouse showing how panels block ground-level access

GPO3 panels create a solid barrier between stored grain and external rodent access, helping reduce common entry points at ground level.

The smooth, hard GPO3 surface is difficult for rodents to grip or chew, helping limit climbing and access over panel edges.

BUILT FOR TOUGH CONDITIONS

✔ GPO3 construction – glass reinforced polyester laminate for structural strength
✔ Hard surface – resistant to rodent chewing and wear
✔ Non-absorbent material – won’t rot, swell or delaminate
✔ Easy to clean – suitable for grain and food environments
✔ Precision CNC machining – consistent fit and repeatable components
✔ Modular system – repair or replace individual sections
✔ Reusable offcuts – retain material for maintenance and patching

WHY GPO3 OVER COMMON MATERIALS

✔ Stronger than plastics – won’t flex, crack or deform under load
✔ More durable than timber or cardboard – does not absorb moisture or degrade
✔ Resistant to rodent damage – unlike softer materials that can be chewed through
✔ Lighter than metal – easier to handle without corrosion issues
✔ Cleaner surface – smooth, non-porous finish reduces contamination risk
✔ Machinable and consistent – precise cut-outs and repeatable panel systems

Example Configuration

Typical Panel System Components

This example shows how GPO3 panels can be arranged in a rodent-resistant containment system. Components are CNC machined and assembled to form a rigid barrier that helps reduce common ground-level entry points.

Main panels form the primary containment barrier
Side covers help eliminate gaps and exposed edges
Base covers close the gap between panel and floor
Support splines provide structural joining between panels
Base supports improve stability and help prevent access underneath

This is an example configuration only. Panel layouts and components can be adjusted based on your measurements and application requirements.

RODENT-RESISTANT PANEL FAQS

Common questions about GPO3 grain containment panels

Practical answers to help you understand how GPO3 panels can be used in rodent-resistant grain storage and containment systems.

Are GPO3 panels completely mouse-proof?

GPO3 panels are best described as rodent-resistant, not guaranteed mouse-proof. They help reduce ground-level access by creating a hard, durable barrier that is difficult for rodents to chew through.

Where are these panels used?

These panels can be used in grain storage areas, feed containment setups, bulk storage enclosures, sheds, bunkers and agricultural containment systems where traditional materials may fail due to chewing, moisture or structural weakness.

Why use GPO3 instead of timber, plastic or cardboard?

GPO3 is a glass reinforced polyester laminate with a hard, non-absorbent surface. Unlike timber or cardboard, it does not rot or absorb moisture. Unlike many plastics, it offers better rigidity and is more difficult for rodents to chew through.

Can the panels be CNC machined?

Yes. GPO3 panels can be CNC machined to suit customer requirements, including cut-to-size panels, fixing holes, cut-outs, ventilation holes and custom shapes.

Do you recommend the panel thickness?

Panel thickness depends on the application, including panel height, fixing method, unsupported span, installation conditions and load requirements. We manufacture and machine panels to suit your measurements or drawings, but final panel selection and system suitability should be confirmed by the customer or installer.

Do I need drawings to request a quote?

Drawings are helpful, but not always required. You can provide basic measurements, photos, sketches or layout details. We can use this information to prepare a quote for custom-machined GPO3 panels.

Can you design the full rodent-resistant system for me?

We supply and machine the GPO3 panels, but we do not provide engineered system design. Panel layout, thickness selection, support requirements and installation method should be determined by the customer, installer or project engineer based on site conditions.

Will this stop rodents climbing over the panels?

The panels are designed to help reduce ground-level rodent access. Overall effectiveness depends on the full site setup, including surrounding walls, roof access, installation quality, panel height and existing rodent activity.

Are these panels held in stock?

GPO3 panels and CNC machined parts are generally supplied to order. Lead times can vary depending on material availability, machining requirements and current supplier workload.
