Hollow balls are lightweight spherical components available in metal and polypropylene (PP). Material, diameter, wall thickness, surface finish and color can be customized for architectural decoration, packaging, floating, liquid-surface covering, mechanical assemblies and other specialized applications.
Available as metal hollow balls or PP hollow balls, these products combine low weight with flexible material, size, finish and color options for different applications.
Metal hollow balls are available in brass, copper, aluminum and stainless steel. Stainless steel options include 201, 304, 304L, 316, 316L and 440, subject to the required size, wall thickness and quantity. They are generally formed and welded, with polished, brushed or untreated surface options available for architectural decoration, displays, art installations and customized industrial projects.
PP hollow balls are lightweight and corrosion-resistant plastic spheres available in different sizes and colors. Depending on the product design, they can be used as internal components in cosmetic and personal-care packaging, as well as in floating, liquid-surface covering, water treatment, drainage systems and other customized applications.
