Product Overview
What This Piece Is
Can be customized to produce various colors
durable AISI304 stainless steel sheet by water presure.
Our technicians calculate the specific data for the welding steel sheet size ,
then bending it to a precise shape, next our qualify workers weld a similar spherical cube shape and
forming a perfect spherical steel balls with particular water pressure. Finally
we’ll grind off the welding seams and mirror polishing it.
Who It Is For
- Sculptors, studios and art consultants
- Architects and landscape architects
- Property developers and public realm teams
- Garden centres, retailers and landscape contractors
Problems It Solves
- A diameter or wall thickness that no distributor stocks
- Thin imported balls that dent in transit and dull within a season
- A weld line that shows in the reflection
- No mounting detail, so fixings are improvised on site
Key Benefits
Why Buyers Specify This Product
A Reflection That Stays Whole
Weld seams are ground and re-polished until a straight line reflected across the surface does not break in two, which is the difference between a sculpture and a divided mirror.
Built to Your Size, Not to a Die
Water pressure forming has no standard die limit, so the diameter comes from your drawing rather than from the tooling a supplier happens to own.
Grade Matched to the Location
304 for indoor placement, 316 or 316L where the piece meets coastal air, marine environments or acid rain.
Mounting Detail Made With the Piece
Base plates, support posts, drilled and tapped holes and fixing centres are fabricated with the work rather than improvised on site.
One Supplier From Drawing to Freight
Our 3D drawing team develops the panels, the workshop forms and finishes the piece, and express, air or sea freight is arranged from here.
Application Scenarios
Where This Product Is Installed
The same piece behaves differently indoors, on a coast and in a fountain basin. These are the settings we build for most often.
Private gardens and courtyards
Single gazing balls from 100 mm up, or a graduated group across a lawn or bed.

Manufacturing Process
How It Is Made
Water Pressure Forming
Technicians calculate the exact developed size for each steel sheet, the sheet is bent into leaf shapes, welded into an approximate spherical cube and then expanded into a true sphere under water pressure. Weld seams are ground off and the surface is mirror polished. There is no standard die limiting the size, so any diameter can be built to a drawing.
Best for: Large and giant spheres, one-off commissions, sizes with no existing tooling
Mould Pressing
Sheet is deformed against a mould, two hemispheres are welded together, the weld seam is ground back and the ball is polished or brushed. Available from 5 mm to 500 mm diameter with 0.6 mm to 6 mm wall thickness, with drilling and tapping to your drawing and invisible weld seams.
Best for: Repeat batches of small and medium balls, gazing balls, drilled and tapped balls
Spinning
Two hemispheres are metal spun and then welded together, ground and polished. This is the route that produces the thickest wall sections we offer.
Best for: Heavy wall spheres and hemispheres, structural or high impact locations
Quality Control
How the Surface Is Judged
Surface Uniformity
A polished surface is judged on whether reflected light is even across the whole ball rather than dark in low lying areas, whether the reflected object stays sharp, and whether it distorts.
Weld Seam Treatment
The weld line is where two panels meet and is the hardest area to finish. If it is not treated correctly the piece reads as a divided mirror and a straight reflected line breaks into two parts, so seams are ground and re-polished until the reflection runs through unbroken.
Material Selection
304 is used for indoor work. For coastal cities and acid rain regions 316 is specified because of its higher corrosion resistance, and we recommend 316 for outdoor sculpture generally. We do not recommend 201 for sculpture work.
We publish the inspection criteria we use rather than a certification badge we cannot evidence.
Comparison
How This Compares With Other Production Routes
| Method | Size range | Thickness | What it gives you | Best suited to |
|---|---|---|---|---|
| Water pressure forming | 19 mm to 5000 mm | 0.6 mm to 6 mm | No die limit, so any diameter can be built | Large spheres and one off commissions |
| Mould pressing | 5 mm to 500 mm | 0.6 mm to 6 mm | Repeatable geometry, invisible seams, drilling and tapping available | Batches of small and medium balls |
| Spinning | Hemisphere based | Thickest wall option | Heaviest sections we produce | Impact exposed and structural pieces |
| Stamping press hemisphere | Φ20 mm to Φ700 mm | 0.6 mm to 3 mm | Consistent batch geometry | Repeat hemisphere and dome components |
| Welded assembled hemisphere | Φ200 mm to Φ3500 mm | 0.6 mm to 3 mm | Large domes with invisible seams | Architectural domes and wall arrays |
Use Guide
Installing and Looking After It
Spheres can sit directly on lawn, gravel or paving, or be mounted on a granite or fabricated steel base. Base plates are made to the fixing centres of the foundation you build. For fountain work the inner pipe, funnel outlet and square base plate are built into the ball.
For daily cleaning use warm water and a cloth, then dry the surface with a towel, because minerals in the water leave marks on stainless steel. A mild neutral cleaning agent removes tough dirt without damaging the surface, and glass cleaner with a microfibre cloth deals with fingerprints. Never scrub a polished ball with a steel wire ball, it leaves scratches that cannot be removed.

FAQ
Questions About This Product
Can this be made in a different size?
Yes. Water pressure forming works without a standard die, so any diameter can be made to your specification between 19 mm and 5000 mm. Send the size you need and we quote against it.
Which stainless steel grade will you use?
AISI 304 for indoor placement and AISI 316 or 316L for coastal cities, marine air and acid rain regions. 316 has better corrosion resistance and durability than 304, and we recommend it for outdoor sculpture. We do not recommend 201.
Will the weld seam show?
No. Seams are ground back and re-polished until a straight reflected line runs across them without breaking. On mould pressed balls the seams are invisible.
Can you add holes, patterns or a logo?
Yes. Drilling and tapping is done to your drawing, spheres can be laser cut with a pattern or perforated with a custom hole layout, and logos or artwork can be sandblasted or etched onto the surface.
What finishes can I choose?
Mirror polish, mill finish, brushed, electroplating, sandblasting, etching, silk printing and sprayed colour in any RAL reference.
How will it be shipped?
Samples and small orders go by air express, usually 5 to 8 days with DHL, UPS, FedEx or Aramex. Medium and urgent orders go by bulk air, around 5 days to your airport. Large orders go by sea, usually 15 to 45 days to your local customs. 7 feet is the largest diameter that ships by conventional freight.
Can you work from my drawing or photographs?
Yes. Our factory has a 3D drawing design team and an in house artist team, and we build from small samples, ideas, 3D drawings or detailed pictures. OEM and ODM commissions are welcome.
