The Stuppy ProLine Fortress targets growers that need maximum clearance and sidewall height for growing applications. A steel bar joist girder frame supports 12’ wide arched peaks. Arches are covered with polyethylene film. The low roof profile minimizes the exposure to wind which reduces heating costs and is easier to cover with polyethylene. The bar joist frame is ideal for automated screening applications and overhead equipment installations. With a ProLine Fortress you can create a controlled environment for growing, install automated shade/blackout systems, utilized automated watering systems, or install overhead cranes.
