High Tunnel

from $7,199Configured to your operation — build yours in the 3D designer for an exact price, then add it to your cart.

The Sun & Steel 100′ Commercial High Tunnel Greenhouse comes in two models to suit any operation. Both feature 6-foot sidewall clearance, dual 8’6″ vehicle-access sliding doors on both ends, full-length 8-foot roll-up vents, insect mesh ventilation, and UV-stabilized poly film on a galvanized steel frame — 6-mil on the Standard, 8-mil on the Heavy.

The Standard Model delivers proven commercial performance with 21 arches at 5 ft on centre — reliable, cost-effective, and built to outperform. The 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 — built for the toughest climates and highest-demand operations.
