Premium Polytunnel Greenhouse (The Premium Kit) - 150km/h Wind Rated - Commercial High-Clearance Structure

Engineered for extremes and built to last a lifetime, the Premium Polytunnel represents the absolute pinnacle of our engineering. This is the ultimate peace of mind solution for high-value commercial operations and the most demanding environments. We’ve upgraded the very foundation of the structure with thicker 42mm steel footings, increased the wall height for a massive internal volume, and reinforced the roof for professional-grade hanging capacity. This is the definitive structure for growers who accept nothing but the best.

Best For Long-term commercial investments, growers in high wind zones or extreme weather areas, and professional enterprises who demand the best in performance, durability, and space.

Key Features

Extreme 150 km/h Wind Rating: Unmatched wind performance, professionally engineered to withstand extreme 150 km/h gusts, making it our top-rated structure for the most exposed and demanding locations.
Expansive Vertical Space: The wall height is increased by 70cm (up to 2.5m), creating a vast, comfortable working environment with more stable air circulation and room for taller, high-yielding vining crops.
Ultimate Foundation: Built with heavy-duty 42mm (2.5mm thick) galvanised steel footings that are inserted 1 metre into the ground for unparalleled, permanent stability.
Superior Roof & Hanging Capacity: Includes horizontal purlins for every hoop, creating a high-strength roof rated for suspending lighting rigs, internal shade screens, irrigation booms, and multiple rows of heavy crops.

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.
Fully Reinforced Pro-Frame: Includes all the features of our Pro range, including 'Top Hat' reinforcement, close spaced arches, and extensive bracing for a truly rigid and robust commercial structure.
10-Year Installation Warranty: An investment grade warranty provides a decade of peace of mind when installed by our professional team.
Includes Protection Felt Tape: Comes with anti-friction felt tape to protect your cover from wear and tear against the steel frame, extending its lifespan.
