Quonset Structures
AHS Cold Frame structures are economical and long lasting! For ground to ground protection use our prepackaged kits available in three styles and a variety of widths and lengths. Arches can be placed 4', 5' or 6' apart depending on wind and snow conditions. Our kits make a 96' long structure when arches are placed at 6' intervals. Coverings not included in kits, please see our Plastics or Shade Cloth pages.
