Designed to Withstand Extreme Weather Conditions

FreestandingThe competitively priced OMNI FREESTANDING greenhouses are designed with superior strength and dependability in mind. Welded reinforced arches provide maximum wind and snow load protection with standard 6′ arch spacing or optional 4′ arch spacing for extreme weather load conditions. The prefabricated slip fit trussed arch design with pre-drilled holes provides a superior strength frame while simplifying assembly and shortening construction time. Omni’s unique 4′ high straight sidewall and open span design give you optimum unobstructed space in the interior of the structure which allows for convenient placement of mechanical systems as well as hanging basket production.

Structures Available in 20, 24, 27, 30, 36, 40 ft. Widths

Every arch is completely reinforced Every arch is completely reinforced from ground to ground thus providing superior strength and durability. Omni’s unique slip fit arch design allows our Freestanding structures to be easily assembled with minimum effort.
Omni's unique poly-saver ridge system Omni’s unique poly-saver ridge system allows you to obtain the maximum life from your poly coverings by producing a smooth ridge line that eliminates arch wear at the peak of the structure where poly is stressed the most.
Condensation drip and snow pocketing Condensation drip and snow pocketing due to purlin contact with the poly film is eliminated by offsetting the purlins to the inner arch.
Gable arches with pre-installed wirelock track Gable arches with pre-installed wirelock track enables quick assembly and provides a positive means of securing both roof and end wall poly layers if required. Gable arches are available with U.V. stabilized rubber closure which provides an excellent seal over the exposed edge of the end wall claddings up to 1″ thick.
8mm twinwall polycarbonate coverings 8mm twinwall polycarbonate coverings offer maximum thermal insulating value and are easily attached to the arch frame thus upgrading your structure to the best in both durability and design.
Aluminum baseboards Aluminum baseboards provide a secure and convenient means of fastening single or multi layer poly film coverings.
Flat Bottom Mounting Brackets Flat Bottom Mounting Brackets are available upon request for anchoring the arches to wooden base rails (wood not supplied) or concrete pads.
Anchor Posts Anchor Posts supplied for every arch provide a secure anchoring of the frame directly to grade. Slip fit arch connections also allow for easier assembly or dismantling for seasonal storage if desired.
Door Frames Door Frames are made of corrosion resistant aluminum and are cladded with clear, impact resistant 8mm twinwall polycarbonate thermal panels.
Gable End Wall Framing Gable End Wall Framing is available for all models. Framing members are 1.5” sq. galvanized tubing that has been pre-cut to the required lengths.
