The 1200 Series 20' Wide Arch Greenhouse can provide year-round production for commercial propagation and growing, retail garden centers and aqua culture. Gothic Arch cold frames are recognized as the strongest, most reliable cold frames available, They’re constructed from the same high-quality, galvanized steel roll-formed components as our more expensive packages. An arch greenhouse is ideal as a starter house or an overflow structure - and it adds classic gothic architecture to a yard or landscape.

Cold frame greenhouse arches are designed for single poly or double poly roof covering. They also can be fitted with shade cloth. Each frame includes pre-cut and punched components for easy bolt-together assembly. By purchasing just the frame, you can personalize the greenhouse build with your choice of covering material, doorways, venting and more. Call us toll-free at 1-888-281-9337 to learn more about cold frame greenhouses.
