A mirrored stainless steel sphere reflects its surroundings—the sky, trees, buildings, and people—which makes it particularly effective in parks, squares, and interiors. But a mirror shine does not appear on its own: it is the result of a multistage surface finishing process.
A sphere is usually assembled from separate welded sections. After welding, the seams are ground down and leveled so that the form reads as a unified whole, without visible transitions.
The surface is then sanded progressively, moving from coarser abrasives to increasingly finer ones. Each successive stage removes the scratches left by the previous one. The more carefully these steps are performed, the clearer and smoother the final reflection will be.
The final stage is polishing with compounds to achieve a mirror shine. On a sphere, any unevenness is immediately visible in the reflection, so this stage requires attention to every part of the surface.
How to care for a mirror finish: stainless steel resists corrosion, but dust and rain marks accumulate on it outdoors. Usually, periodically washing the surface with water and a mild cleaner and wiping it with a soft cloth is enough. Avoid abrasive sponges.
Photos of the manufacturing stages can be found on the “Production” page, and finished options in the “Balls and Spheres” catalog section.
