A hollow stainless steel sphere designed for outdoor garden spaces, this piece functions as a reflective ornament that captures sky, foliage and surrounding architecture, turning a simple form into a dynamic visual element. It is built for gardens, courtyards and landscape features where a polished, lightweight sphere adds modern contrast to planting or paving.

Application Scenarios
Where It Is Installed
- A private garden where a single polished sphere acts as a focal point among shrubs and pathways
- An urban courtyard that needs a reflective object without the bulk of a figurative sculpture
- A residential entrance where the sphere reflects the house facade and sky from the driveway

- A need for a durable, low-maintenance ornament that won’t degrade in outdoor weather
- A design that requires a polished surface but cannot use glass or fragile materials
- A project with a specific diameter in mind that doesn’t match standard off-the-shelf sizes
- A client who has a reference image but no technical drawing for a custom sphere
Technical Features
How It Is Built
- Hollow shell formed from two hemispheres joined at the equator and welded together
- Welds ground and hand polished to blend with the surrounding surface
- Wall thickness between 1 mm and 4 mm, depending on the size and structural need
- AISI 304 or 316 stainless steel body, chosen based on environmental exposure
- Hand polished finish applied after welding and shaping to achieve a smooth surface
- Custom diameter as standard, not as a special order, with no fixed size limit
Materials
Body Materials and Where Each One Suits
- AISI 304 stainless steel for general outdoor garden use in temperate climates
- AISI 316 stainless steel for gardens in coastal areas or where de-icing salts are used
- Hand polished finish that enhances reflectivity and gives a smooth, clean surface
- 1 mm to 4 mm wall thickness, selected based on size and structural load
- Custom colour available upon request, though the base finish is polished metal
Manufacturing Process
How the Part Is Made
- Scheme design based on the garden setting, including size, placement and visual impact
- Two hemispheres formed over a mould, with internal support designed during shaping
- Welded at the equator and ground down to remove visible seams
- Hand polished to achieve a smooth, reflective surface across the entire shell
- Internal soft foam added before packing to protect the surface during transit
- Final packaging in a sturdy wooden or iron box for door to door delivery
Quality Control
What Is Checked Before It Ships
- The company states it runs its own professional QC team
- Welds are ground and polished to match the surrounding surface, not left raised
- Hand polishing is applied after welding to ensure no marks or unevenness remain
- Internal soft foam and external wooden or iron box protect the polished surface in transit
Customization
What Can Be Changed to Suit You
- Any diameter on request, from 20 inches up to 36 inches and beyond
- AISI 304 or 316 stainless steel selected based on the garden’s exposure
- Hand polished finish applied uniformly across the entire surface
- Custom colour available upon request, though the base finish is polished metal
- Ordered from a photograph or a drawing supplied by the customer
- Base and fixing detail designed to suit the garden surface and wind load
Comparison
How It Compares With the Alternatives
| A painted steel sphere | Painted steel may cost less initially but requires repainting over time; stainless steel maintains its finish permanently, which is why it is used in long-term outdoor installations |
|---|---|
| A solid metal sphere | Solid spheres are heavier and more expensive at large sizes; this hollow version reduces weight while keeping structural strength |
| A fiberglass sphere | Fiberglass is lighter and cheaper but cannot be hand polished to a mirror finish; it is better suited for indoor or low-exposure settings |
| A corten steel sphere | Corten changes over time with weathering; this polished stainless steel sphere is chosen when the surface must remain consistent and reflective |
Use Guide
Fitting and Running It
- Choose the diameter based on the garden’s scale, not on a standard size from a catalogue
- Place the sphere where it has something to reflect: sky, trees, or a building facade
- Ensure the base and fixing are designed for wind load, especially at larger diameters
- Clean the hand polished surface with water and a soft cloth; avoid abrasives that damage the finish
- Specify AISI 316 if the garden is near the coast or exposed to salted winter roads
- Plan 20 to 30 days production after deposit, plus sea freight, when scheduling the installation
