Free Air Series


The trusses, purlins and gutters in the Free Air Series 4000 Greenhouse features Superior strength ROLL-FORM steel for unmatched structural integrity. ROLL-FORM sections direct more strength to the longer axis of the metal. Conley's use of COLD FORMING procedures protect the metal's galvanizing features.

Anti-Condensate Control

Conley's Free Air Series include Anti-Condensate control features built directly into the frame. ROLL-FORM mills allow Conley's the ability to form channels into ROLL-FORMED sections to intercept and remove condensate that is naturally generated within the greenhouse. This feature is essential in helping promote a longer life in the structure and covering.
