Pro-Series Walk-In Tunnel Greenhouse – 4m x 2m Galvanised Steel (8sqm)

Take your horticultural pursuits to the next level with our 4-metre Pro-Series Walk-In Tunnel Greenhouse. Offering a sprawling 8$m^2$ of protected growing space, this structure is engineered for durability with a heavy-duty galvanised steel frame and a reinforced 140g/m² PE cover. Whether you’re establishing a year-round vegetable supply or protecting high-value exotic plants, this tunnel provides the stability and climate control needed to thrive in the unpredictable Australian weather.

Best For

Serious home gardeners, hobby farmers, and those in colder Victorian regions who require a large, permanent-style walk-in structure with superior corrosion resistance.

Key Features

• ✔ Corrosion-Resistant Galvanised Steel: Built with an exceptionally strong galvanised steel frame. Unlike standard painted frames, galvanisation provides a deep layer of protection against rust—essential for high-humidity greenhouse environments.

• ✔ Reinforced 140g/m² PE Cover: The heavy-duty green polyethylene cover is UV-resistant, frost-safe, and anti-tear. It’s designed to trap heat for "warm house" performance while acting as a rugged shield against wind and birds.

• ✔ 4-Window Ventilation System: Features four independent roll-up mesh windows (40 x 40 cm). This allows for precision cross-ventilation, preventing heat-stress and fungal issues during the humid autumn and spring months.

• ✔ Massive 8sqm Footprint: With a 4m length and a full 2m head clearance, this greenhouse comfortably accommodates multiple rows of garden beds, central aisles, and staging benches.

• ✔ High-Access Roll-Up Door: The 100 x 185 cm zippered door provides effortless "in-and-out" access, even when carrying large seed trays or maneuvering wheelbarrows.

Oversized Item Delivery Options

Since oversized items require special handling, we may need to provide a custom freight quote for your order and will contact you with an updated shipping rate.

Available options include:

✔ Delivery to your closest depot for pickup - default method
✔ Direct delivery - requires forklift on site
✔ Direct delivery with tailgate lift truck (extra fees apply)
✔ 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
• Because of the forklift requirement, delivery to the nearest depot is the default option and will be the method used unless you contact us to request otherwise.

Business Delivery:

• Business delivery is available for commercial customers only
• If you select business delivery and your products are bulky, it is your responsibility to ensure you have appropriate equipment (including forklifts) to unload products from the delivery truck
• If you select business delivery and you are not a business, you risk your product not being delivered and may incur additional fees to retrieve your order
• Business delivery customers must provide a valid business address and contact information
• Additional fees may apply for failed delivery attempts due to lack of appropriate unloading equipment

Let us know your preference, and we'll arrange the best solution for you!

Important Note on Availability & Shipping

Our warehouse serves as our office and logistics centre rather than a retail showroom. Because we ship from multiple locations and manage high-turnover stock, not all items are available for immediate pickup.

Lead Times:

• In-Stock Items: Usually ready for dispatch the same day.
• Supplier-Dependent Items: Usually take 2–8 weeks to arrive, depending on supplier availability. Products from Adloheat may take 8–12 weeks to manufacture—they are made to order in Australia by a small business, and longer lead times reflect the care put into quality.

While we strive for fast delivery, some timelines are subject to supplier availability and are beyond our control. We appreciate your patience as we source the best quality gear for your project.

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.
