Certified Structures
Find Your Greenhouse Match
Each structure is rated against NBCC & ASCE snow load standards. See how our greenhouses perform at every PSF range — from mild coastal winters to extreme mountain snow.
What does PSF mean for your structure?
<10 PSF — Light as a dusting. Minimal load; virtually any structure handles this. 10–20 PSF — Moderate snowfall. Standard structural steel manages comfortably. 20–35 PSF — Heavy accumulation. Reinforced framing becomes important. 35–50 PSF — Serious load. Commercial-grade steel & closer purlin spacing required. 50–80 PSF — Near-mountain conditions. Heavy-duty trusses essential. 80+ PSF — Extreme alpine zones. Engineering sign-off recommended.
At 25 PSF, this structure handles moderate seasonal snowfall — climates where winter shows up but doesn't overstay its welcome. A solid all-around choice for growers who see regular snow but not the heavy sustained loads of colder inland regions.
At 70 PSF, this is built for serious winters — sustained, heavy, and unforgiving. Thicker steel throughout, arches set tighter together, and two extra purlin runs give it nearly triple the capacity of the Standard.
At 15 PSF, this structure is designed for mild climates where winter is light and snow is rare or fleeting. It's not built to carry a load — it's built to be economical, fast to erect, and effective where the weather cooperates.
At 50 PSF, this is the hoop tunnel built for real winters. Thicker steel, tighter arch spacing, and two extra purlin runs transform the same semicircular footprint into a structure that handles serious seasonal snow with confidence.
Same structural DNA as the 100ft Standard — identical arch geometry, bay spacing, and pipe spec — just half the length. Rated for moderate seasonal snowfall where winter shows up regularly but doesn't linger at extreme depths.
At 75 PSF, this is the most capable structure in the lineup for its footprint. Tighter arch spacing and heavier steel than the 100ft Heavy give it a higher per-bay rating — built for harsh winters where you need maximum confidence in a compact space.
Same structure as the 100ft Hoop Standard, just half the length. Built for mild climates where the economics of a hoop make sense — fast to erect, cost effective, and perfectly capable where winters stay manageable.
At 55 PSF, this punches well above a typical hoop tunnel. Tighter arch spacing and heavier steel turn a compact footprint into a structure ready for sustained winter conditions — without the wall height of a high tunnel.
The most compact light deprivation structure in the lineup — same arch geometry and wall height as the larger models, squared down to a 30ft footprint. Built for growers who need full photoperiod control without committing to a larger structure.
At 80 PSF, this is the highest rated structure in the lineup and the most capable light dep footprint we offer. Nine arches packed into a 30ft run with tighter spacing than any other model — full blackout control with heavy-winter capability built in.
