High Tunnel Mini

The Sun & Steel High Tunnel Mini is a compact, fully trussed greenhouse designed for home growers, market gardeners, and anyone who needs a serious steel structure in a smaller footprint. At 8 feet wide, 10 feet at the peak, and 7 feet at the sidewall, it delivers genuine commercial-grade construction — a galvanized bottom cord, W-diagonal, and return pipe form a real truss system on every interior arch — without the scale or cost of a full-width tunnel.

The Standard brings 4-ft-on-centre gothic arches, 3 purlin runs, and a ground-driven anchor system with no concrete required. The Heavy tightens the arch spacing to 3 ft on centre, adding roughly 33% more structural capacity in the same footprint — the right call for growers in colder climates or anyone planning to run it through a real Northern winter. Available in 12 ft, 24 ft, and 36 ft lengths; the reference build below is the 24 ft length (7 Standard / 9 Heavy arches). Both models include a UV-stabilized poly film system with aluminum channel throughout — 6-mil on the Standard, 8-mil on the Heavy.
