A gravity steam industrial iron box is a heavy-duty, self-contained ironing system used in commercial settings like garment factories and dry cleaning shops. Unlike standard irons, it doesn't require a separate boiler; instead, a water bottle is suspended above the ironing surface, using gravity to feed water to the iron. This water is then heated by an electric element within the iron to produce continuous, powerful steam. It features a robust soleplate, often with precise temperature and steam controls, designed for high-volume, continuous use on various fabrics, ensuring efficient wrinkle removal and professional finishing.
