Stainless Steel Hemisphere
stainless steel hollow metal sphere
A hollow stainless steel sphere is designed for outdoor placement in gardens, parks, or public squares, where its mirror polished surface reflects the sky, surrounding planting, and passing people. This piece is made from 304 or 316 stainless steel, with a finish that enhances its visual presence without distortion. The listed size is custom size, and like all items in this catalogue, it is built to any diameter on request. The body is formed by welding two hemispheres, then polished to a mirror finish, making it suitable for modern public art installations.

Key Benefits
What This Nozzle Gives You
- Mirror polish creates a dynamic reflection that changes with light and movement
- Hollow construction reduces weight at large diameters, simplifying installation
- 304 for general outdoor use or 316 where exposure to salt or de-icing chemicals is expected
- Finish applied to the same shell, so mirror, brushed or painted options are consistent
- Custom diameter as standard, not as a special order, allowing exact fit to the space
- Wooden crate with inner plastic or foam packing protects the surface during transit
Application Scenarios
Where It Is Installed
- A garden or park where a single reflective object must stand out against grass and trees
- A public square that needs a central feature without a figurative form
- A hotel entrance forecourt where the sphere acts as a visual anchor before the building
- A corporate campus lawn where the sphere contrasts with paved areas and glass façades
- A shallow water feature where the reflection is doubled by the pool surface
Who It Is For
Buyers Who Specify It
- Landscape architects specifying a focal object for a garden or open plaza
- Property developers commissioning a landmark for a residential or commercial site
- Hotel and resort designers placing a piece in an arrival court or courtyard
- Art consultants sourcing a contemporary reflective sphere within a fixed scope
- Municipal clients replacing an existing centrepiece with a durable, low-maintenance form
Problems It Solves
What It Fixes on the Line
- An open garden or park that lacks a visual anchor and reads as empty
- A forecourt with no room for a figurative sculpture but needs a landmark
- Off-the-shelf spheres that come in only three sizes, none of which fit the space
- Painted steel features that degrade and require frequent repainting
- A commission based on a photograph with no technical drawing or scale
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 finished surface
- 304 or 316 stainless steel body selected based on environmental exposure
- Mirror, brushed or painted finish applied to the same shell for consistency
- Custom diameter as standard, not as a special order, to fit the site precisely
Materials
Body Materials and Where Each One Suits
- 304 stainless steel for general outdoor exposure in non-coastal areas
- 316 stainless steel where salt air, road de-icing, or high humidity is present
- Mirror polish that reflects the surrounding environment with clarity
- Brushed finishing that reduces glare and hides minor handling marks
- Painting where the design requires colour rather than reflective surface
Manufacturing Process
How the Part Is Made
- Scheme design against the site to define form, scale and finish
- Small model created and scaled up with internal support structure designed
- Plaster mould taken from the model for precision shaping
- Steel plate forged to the mould and ground repeatedly to build the shell
- Surface polished mirror, brushed or sprayed based on the specification
- Welded assembly and final finish applied on site to ensure joint quality
Quality Control
What Is Checked Before It Ships
- The company states it runs its own professional QC team
- Weld between hemispheres is ground and polished to be flush with the surface
- Repeated grinding before polishing is part of the published method
- Inner plastic or foam padding inside the wooden crate protects the surface
Customization
What Can Be Changed to Suit You
- Any diameter to specification; the company states spheres from 25 mm to 10 m
- Mirror, brushed, painted or coloured finish available
- 304 or 316 body selected based on site exposure
- Ordered from a photograph or a drawing supplied by the customer
- Base and fixing detail designed with the piece for site-specific installation
Comparison
How It Compares With the Alternatives
| A painted mild steel sphere | Painted steel is cheaper upfront but requires repainting every few years; stainless steel maintains its finish permanently |
|---|---|
| A concave mirror piece | A concave face distorts and inverts the reflection at close range; a full sphere reads clearly from all distances |
| A fiberglass sphere | Fiberglass is lighter and cheaper at large sizes but cannot be polished to a mirror finish and is not suited for outdoor exposure |
| A corten steel form | Corten is chosen for its weathered, changing surface; a mirror sphere is chosen when the surface must remain unchanged |
Use Guide
Fitting and Running It
- Set the diameter against the open space around it, not against a catalogue size
- Place the sphere where it has something worth reflecting: sky, planting, or building façade
- Allow for a foundation and fixing detail sized for wind load at large diameters
- Clean a mirror surface with water and a soft cloth; avoid abrasives that damage the polish
- Specify 316 rather than 304 if the site is coastal or salted in winter
- Plan 25 to 30 days production plus 15 to 20 days transport from the installation date
Questions Buyers Ask
stainless steel hollow metal sphere Questions
What size is this stainless steel sphere and can it be made larger?
This stainless steel hollow metal sphere is made to custom size. The company states stainless steel spheres from 25 mm to 10 m in diameter, so it can be built to any required scale.
Which stainless steel grade will I get?
This sphere is made in 304 or 316 stainless steel. Tell us whether the site is coastal or exposed to road salt, and we will confirm the most suitable grade.
Mirror, brushed or painted finish?
All three finishes are available for this piece. Mirror gives the strongest reflection, brushed reduces glare and hides handling marks, and painting is used when colour is needed.
How long from order to delivery for this sphere?
The production time is 25 to 30 days. Transport takes 15 to 20 days, so plan accordingly from the date the site must be ready.
How is this polished sphere packed?
It is packed in an outer standard wooden crate with inner plastic or foam protection, which is standard for preserving the polished surface during transit.
Can you build one from a picture I have?
Yes. The workshop takes orders based on a photograph or a drawing from the customer. Send the image, the desired diameter, and the intended location.
