Walk-In Tunnel Greenhouse with Galvanized Steel Frame

Protect and Extend Your Growing Season

This walk-in tunnel greenhouse is designed to create a stable, controlled environment for vegetables, flowers, and fruits throughout the year. Available in four sizes (10 x 7 x 7 ft, 12 x 7 x 7 ft, 15 x 7 x 7 ft, and 20 x 10 x 7 ft), it offers flexible options for small gardens, allotments, and larger growing areas.

The structure is built around a galvanized steel frame that resists rust and provides reliable support in everyday weather conditions. A 140 g/m² PE (polyethylene) cover forms a protective shell around your plants, helping to shield them from rain, wind, and excessive sun exposure. Roll-up mesh windows along the sides (6, 8, or 12 depending on size) allow you to fine-tune airflow and temperature while keeping insects and debris out. The full-height walk-in design gives you comfortable access for watering, pruning, and harvesting.

Each size offers generous interior space for staging, raised beds, or container gardening. The included stakes and guy ropes help secure the greenhouse to the ground, while diagonal support poles and top beams enhance overall stability. The frame assembles with basic tools, and the cover fits over the structure for straightforward seasonal installation and removal.
