CZANT is a planter box made from steel. Zinc painted primer and then oven powder painted creates a hard finish, that is tougher than any conventional paint. Standard colour is RAL 7016, other are optional.
The bottom is a slatted grate that allows easy drainage and good air circulation to roots. Walls are thermally insulated from the inside to prevent root overheating. Very solid and rigid construction allows to plant heavy plants. Optionally, tropical wood elements can be added for more attractive look.
