The Sun & Steel 50′ Commercial High Tunnel Greenhouse brings full commercial performance to a compact footprint. Both models include 6-foot sidewall clearance, dual 8’6″ vehicle-access sliding doors on both ends, full-length 6-foot roll-up vents, insect mesh ventilation, and 6-mil UV-stabilized poly film on a galvanized steel frame — the same proven feature set as the 100′ models, scaled for smaller operations.
The Standard Model features 11 arches at 5 ft on centre — a solid, cost-effective structure ideal for growers adding capacity or starting out at a commercial scale. The Heavy Model steps up to 13 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 same uncompromising build as the 100′ Heavy in a tighter, more manageable size.
Price range: $7,999.00 through $9,999.00
