The Sun & Steel 50′ Commercial Hoop Tunnel Greenhouse is a wider, lower-profile alternative to the traditional high tunnel — spanning 30 feet wide and rising to a 14-foot peak with full 8-foot standing clearance across the entire interior. Both models include dual 8’6″ vehicle-access sliding doors on both ends, full-length roll-up sides, insect mesh ventilation, and 6-mil UV-stabilized poly film on a galvanized steel frame.
The Standard Model features 21 arches at 5 ft on centre — dependable commercial performance at an accessible price point. The Heavy Model steps up to 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 — maximum strength in a compact, versatile footprint.
Price range: $6,999.00 through $8,999.00
