Like the circular flat top and bottom water tank, an imported corrugated rolling machine is used to roll the ribs on the surface of the stainless steel plate, forming uniformly distributed corrugated reinforcement ribs, greatly improving the strength and toughness of the plate, thereby making the water tank more sturdy. At the welding point, there is a horizontal "insulation, cold water" stamped cover and a manually rolled rib cover. There is no water accumulation at the top of the water tank, and the insulation performance is bright. It is welded using a DC high-frequency pulse welding machine, and the joint is formed in one go, with strong tensile strength and beautiful and sturdy appearance. Material description; The water tank plate is made of food grade SUS304 stainless steel with a nickel content of over 8%, ensuring that the steel plate will never rust and has a service life of over 30 years. According to customer needs, high-quality 304 stainless steel can be selected for lightweight and beautiful appearance.
