The lineup

Gothic or Round: same kit, two roof lines.

Both share a steel ridge purlin, cross connectors, and ground posts. The difference is the hoop: a peaked profile, or a round profile that's lighter and easier to move.

Gothic: peaked profile
Peaked profile

Gothic

Peaked profile · galvanized steel hoops

How it goes together

No bending hoops. No parts runs.

Every frame ships kitted: cut, drilled, and ready to raise.

01

Set the posts

Drive 3′ or 4′ ground posts on your bow spacing: 4′ or 5′ on center.

02

Raise the bows

Slip Gothic or Round hoops over the posts and tie them with the ridge purlin and cross connectors.

03

Choose your options

Add roll-up sides, wind ropes, or the options your plan calls for. We'll help you spec it.

04

Skin & close up

Pull the poly covering, lock the end bows with wirelock, and finish with steel or wooden end walls.

Thinking about NRCS funding?

Many growers fund season-extension structures through USDA-NRCS cost-share under Conservation Practice Standard 325. CPS 325 is written around fixed, anchored high tunnel structures, so a caterpillar tunnel may not qualify. Check with your local NRCS office. If NRCS funding is the goal, our high tunnel line is the more direct path.
