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.
