30 ft × 200 ft Commercial Hoop Tunnel Greenhouse Kit — Super Heavy Frame

$25,997

The Sun & Steel Commercial Hoop Tunnel Greenhouse brings the wide-open hoop design to full large-scale production. Spanning 30 feet wide and up to 300′ long, with a 14-foot peak and 8-foot interior standing clearance from end to end, both models include dual 8’6″ vehicle-access sliding doors on both ends, full-length roll-up sides, insect mesh ventilation, and UV-stabilized poly film on a galvanized steel frame — 6-mil on the Heavy, 8-mil on the Super Heavy. At 200 ft, the Standard frame carries 2,418 kg of structural steel, the Heavy 4,678 kg and the Super Heavy 7,620 kg — that weight is how you know it’s built for any environment.

The Heavy Model features 21 arches at 5 ft on centre — a proven, cost-effective structure for high-volume growing operations. The Super Heavy Model pushes further with 26 arches at 4 ft on centre, 2.5 mm arch walls, a three-tier W-support truss on every arch, and heavier pipe diameters throughout — the strongest commercial hoop greenhouse we build.

The Sun & Steel app

Automate your Hoop Tunnel in the Sun & Steel app

The Smart Thermostat reads the temperature and humidity in the house. When it warms up, the app opens the roof vents, rolls up the sides and runs the exhaust fans; when it cools off at night it closes them and draws the thermal curtain. The irrigation controller waters each bed on its own schedule.
