In addition to size, the material of a cold frame also plays a crucial role. Specially developed aluminium profiles ensure high load capacity of the structure. The frame construction is made of aluminium. The side curved aluminium brackets are powder-coated and oven-baked in the colour RAL 6009 fir green. The basin and other aluminium profiles are silver anodized. Plant table floor and shelf floor are made of ISO twin-wall-sheets (without shelf – ideal for wheelchair users). The panes are made of shatter-proof 2 mm polycarbonate.
