This greenhouse can provide year-round production for propagation and growing, retail garden centers, and aqua culture. Our Conley’s Cold Frames are recognized as the strongest, most reliable Cold Frames available – constructed from the same high quality, galvanized steel roll-formed components as our more expensive packages. Ideal as a starter house or an overflow structure. Cold Frames are non-rated structures and not recommended for high wind or snow areas.


Two-piece arch that laps and bolts together. Three runs of purlins for 16′ model and five runs of purlins for the 20′. 20′ model provides 10′ clearance with more headroom than most structures in its class. Simple to install. Components supplied pre-cut and punched for an easy bolt together assembly. Step-by-step installation instruction are included. Arches nest together for economic shipping.


The success of this Cold Frame can be found in it’s unique rollform components offering superior strength, reduced cost, and simplified installation. The galvanized steel frame insures maximum strength and life. Each model is designed for single poly or double poly roof covering and includes pre-cut and punched components for easy bolt-together assembly. Also can be fitted with shade cloth.

Structural Design Features

Superior Strength Rollformed Technology

Rollformed components incorporate the same design principle applied to industrial “I” Beams. Engineered to be longer than wide, these rollformed members offer substantially greater resistance to the deflection causing forces of rain, snow and wind when compared to conventional greenhouse components.

Patented Condensate Removal Systems

As condensation forms inside a greenhouse, it runs down the roof until it reaches an obstacle such as a purlin. In standard greenhouse designs, the condensate falls to earth upon contact with the purlin. Our truss and purlin assemblies, however, incorporate unique built-in anti-drip channels which intercept the condensate, effortlessly directing it away from people and plants.

Cantilevered Gutters

Our gutters are cantilevered a full 2 feet over greenhouse columns, transferring the normal loads created by gutter connections away from the column. This feature increases the strength and stability of the structure. Gutters also lap one into the other, virtually eliminating connection leaks.
