A greenhouse is a cultivation device for indoor greenhouses, mainly including planting troughs, water supply systems, temperature control systems, auxiliary lighting systems, and humidity control systems. The greenhouse skeleton is made of hot-dip galvanized pipes, with flat and smooth welding seams, good rigidity, wind and snow resistance, and composite (double-layer rock wool insulation) materials for the back slope of the covered greenhouse for insulation. Single, good sealing performance. Due to the adoption of hot-dip galvanizing and anti rust treatment on the surface of the skeleton, its service life is longer than that of general welded pipe or steel bar structures.
