The 304 stainless steel insulated water tanks feature a novel, beautiful, and generous design, assembled from unit rectangular blanks or corrugated plates through arbitrary assembly and welding. They can be freely combined according to different site requirements into various shapes such as polygons, stepped, and L-shaped SUS304 stainless steel water tanks. The tanks have a smooth line, a strong sense of three-dimensionality, and can beautify the urban landscape.
