Polytunnel Pro Kit

Commercial Polytunnel Greenhouse (The Pro Kit) - 130km/h Reinforced Frame - for Commercial Growers & Exposed Locations

When your livelihood depends on the performance of your structure, there is no room for compromise. The Pro Polytunnel is our commercial-grade workhorse, engineered from the ground up for demanding conditions and larger-scale operations. We've significantly reinforced the entire frame with closer arch spacing and extensive steel bracing, creating a structure designed to stand firm in challenging weather and protect your valuable investment year after year.

Best For Commercial enterprises, growers in exposed locations, and anyone who demands exceptional structural integrity and larger-size formats for their operation.

Key Features

• ✔ Heavily Reinforced Frame: Features closer arch spacing (1.32m), stronger end-wall supports, and 8 support brackets, all working together to create a structure of superior rigidity and strength.

• ✔ Ultimate Wall Reinforcement: Includes two full rows of steel 'Top Hat' channels, providing immense strength against lateral wind loads from severe storms.

• ✔ 130 km/h Severe Wind Rating: Professionally engineered to withstand powerful, 130 km/h storm-force winds, making it the ideal choice for exposed, high-wind, or coastal locations.

• ✔ Premium 5-Piece Cover: Features Australia's toughest 250-micron EVA film (Anti-UV, Anti-Drip, Anti-Fog) in a multi-piece design, which allows for easier installation and maintenance on large structures.

• ✔ Expanded Size Options: Available in lengths up to 35 metres to accommodate serious, large-scale growing operations.

• ✔ High Roof Load Capacity: Rated for a 30kg/m² roof weight, easily handling maintenance loads or supporting trellised crops (e.g., tomatoes, cucumbers).

Oversized Item Delivery Options

Oversized, heavy, and structural goods ship via specialist freight. Freight is calculated at checkout from estimated packaged volumetric or physical weight. Carrier depot audits may adjust the rate — if the increase exceeds 10%, we will contact you before processing.

Available options include:

✔ Delivery to your closest depot for pickup — default method
✔ Direct delivery — requires an operational forklift on site unless Tailgate Delivery has been specifically requested and quoted (contact us — this cannot be selected at checkout)
✔ Tailgate hydraulic lift delivery — must be specifically requested; contact us for a quote (not available as a checkout option; extra fees apply; required if you do not have a forklift)
✔ Forklift loading at our warehouse (no extra charge if you arrange your own freight)
✔ Direct truck delivery (available in Victoria)

Important Notes:

• Shipping costs vary by location and method
• Any carton or consignment over 25–30kg (or over 200cm) must be palletised
• Without a specifically requested and paid Tailgate Delivery quote, palletised freight requires a forklift on site — otherwise the carrier will redirect to the nearest depot
• Bulky and oversized items cannot be delivered to a PO Box — provide a physical street address
• Failed deliveries, locked gates, unattended sites, or incorrect business/forklift declarations may incur carrier redelivery, demurrage, and restocking fees as set out in our Terms & Conditions

Business Delivery:

• Selecting a business/commercial delivery rate warrants that the address has an operational forklift and certified operator during business hours
• If the carrier cannot unload, the consignment may be redirected to a depot and secondary fees may apply
• Additional fees may apply for failed delivery attempts due to lack of appropriate unloading equipment

See our Terms & Conditions (Article 8) for full freight and delivery rules.

Important Note on Availability & Shipping

Our warehouse is a logistics hub, not a retail showroom. Listing a product online does not mean it is stored at our Thomastown warehouse — many lines ship from supplier hubs (split fulfilment may apply).

How lead times work:

• Product page ETA: The Estimated Time of Arrival (ETA) / lead-time badge shown on the product page at checkout is the agreed delivery timeframe for that order under Australian Consumer Law.
• Metro baselines: Advertised ETAs apply to standard metropolitan zones. Regional and remote addresses may take longer and may attract surcharges.
• Peak seasons: Orders in March–May, August–October, EOFY (June), Black Friday/Cyber Monday (November), and Christmas/New Year (December–January) may automatically add a 2–4 week buffer beyond the product page ETA.
• Supplier-dependent / backordered items: If stock is delayed, we will notify you with a revised ETA. You then have 7 days to accept the new timeframe or cancel for a full refund.
• Adloheat: Custom-made products from Adloheat (Pakenham, VIC) may take 4–12 weeks depending on the order.

Full fulfilment, cancellation, and freight rules are in our Terms & Conditions.

Biosecurity & Interstate Shipping Restrictions

Due to strict state biosecurity regulations, we are unable to ship some products to certain states and territories:

• Potting Mixes cannot be shipped to Western Australia (WA), the Northern Territory (NT), or Tasmania (TAS).
• Seeds cannot be shipped to Western Australia (WA).

Orders placed for these items to restricted states will be cancelled and refunded. It is the customer's responsibility to ensure that the items being ordered can lawfully be delivered to their state or territory.
