Technical Features
How It Is Built
- Hollow shell formed from two hemispheres welded together over a mould
- Weld joint ground and polished to be invisible on the final mirror surface

Materials
Body Materials and Where Each One Suits
- 304 stainless steel for general outdoor exposure in urban or suburban areas
- 316 stainless steel for coastal locations or areas where road salt is used in winter
- Mirror polish provides a reflective surface that shows the environment in real time
- Hollow construction keeps the weight manageable at large diameters
- Stainless steel resists rust and maintains finish without repainting
Manufacturing Process
How the Part Is Made
- Scheme design developed in relation to the site’s scale, light, and context
- Small model created and scaled up to determine form and internal support
- Plaster mould taken from the model to shape the metal shell
- Steel plate forged to the mould and ground repeatedly to build the shell
- Surface polished to mirror finish after welding and grinding
- Final assembly and installation with welded joints finished in place
Quality Control
What Is Checked Before It Ships
- The company states it has its own professional QC team
- Welds are ground and polished to be invisible on the finished mirror surface
- Repeated grinding is part of the published method before final polishing
- Inner plastic or foam protection inside the wooden crate prevents surface damage
Customization
What Can Be Changed to Suit You
- Available in sizes from 3 to 9 meters, with custom diameters possible
- 304 or 316 stainless steel selected based on site exposure
- Mirror finish applied to the entire shell, no partial finishes
- Orders accepted from a photograph or technical drawing provided by the customer
- Base and fixing system designed to suit the site’s wind load and foundation
Comparison
How It Compares With the Alternatives
| A painted steel sphere | Painted steel requires repainting every few years; stainless steel maintains its finish permanently |
|---|---|
| A concave mirror piece | A concave surface distorts and inverts reflection at close range; a full sphere reflects clearly from all angles |
| A fiberglass sphere | Fiberglass is lighter and cheaper but cannot be polished to mirror; it is better suited for indoor or sheltered use |
| A corten steel sculpture | Corten changes over time with weathering; this mirror sphere is designed to remain unchanged |
Use Guide
Fitting and Running It
- Choose the diameter based on the scale of the surrounding space, not on catalogue sizes
- Place the sphere where it has a meaningful reflection: sky, trees, buildings, or water
- Ensure the foundation and fixing system are sized for wind load at large diameters
- Clean the mirror surface with water and a soft cloth; avoid abrasives that damage the polish
- Specify 316 stainless steel if the site is near the coast or experiences winter de-icing
- Plan 25 to 30 days for production plus 15 to 20 days for transport from the factory
