Stainless Steel Hemisphere
large metal spheres 24 large stainless steel hollow balls 100mm stainless steel ball
A hollow stainless steel hemisphere is a finished, laconic geometric form designed for placement in gardens, halls, or public squares, where its curved surface reflects the surrounding space with a sense of mystery and precision. This piece is made from 304 or 316 stainless steel, with a mirror, brushed, or painted finish, and is available in a standard size of 100 mm, though it is made to any custom size on request. The body is formed by shaping plate over a mould, welding two hemispheres, and polishing the joint to invisibility. The listed production time is 25 to 30 days, with transport taking 15 to 20 days, and the piece is packed in an outer wooden crate with inner plastic or foam protection.

Key Benefits
What This Nozzle Gives You
- A mirror, brushed or painted finish allows the hemisphere to reflect or soften the environment, depending on the setting
- Hollow construction reduces weight while maintaining structural integrity at larger diameters
- 304 stainless steel for general outdoor use or 316 where exposure to salt or de-icing chemicals is expected
- Custom size as standard, not a special order, with the company stating spheres from 25 mm to 10 m in diameter
- Production time of 25 to 30 days, with transport taking 15 to 20 days, allowing for planning against site timelines
- Wooden crate with inner plastic or foam packing protects the polished surface during transit
Application Scenarios
Where It Is Installed
- A garden feature where a single hemisphere acts as a focal point amid planting or paving
- An interior hall or lobby where the curved surface reflects light and architectural details
- A public square where the hemisphere stands as a minimalist landmark with a reflective surface
- A hotel entrance courtyard where the form adds modern contrast to traditional materials
- A corporate lobby where the hemisphere reads as a contemporary object with visual depth
Who It Is For
Buyers Who Specify It
- Landscape architects specifying a minimal geometric form for a garden or plaza
- Hotel and property developers commissioning a modern sculptural element for an entrance
- Interior designers placing a reflective object in a high-traffic public space
- Art consultants sourcing a precise, geometric sculpture for a curated collection
- Municipal clients replacing an existing feature with a durable, low-maintenance form
Problems It Solves
What It Fixes on the Line
- A space that lacks a clear visual anchor but cannot accommodate a large figurative sculpture
- A commission with only a reference image and no technical drawing, which can still be built
- A need for a durable outdoor sculpture that resists corrosion and weathering over time
- A desire for a reflective surface that changes appearance with light and viewer position
- A project requiring a piece that can be made in any size, not limited to standard catalogue dimensions
Technical Features
How It Is Built
- Hollow shell formed by shaping stainless steel plate over a mould and welding two hemispheres
- 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, ensuring consistency
- Custom diameter as standard, with the company stating spheres from 25 mm to 10 m in diameter
Materials
Body Materials and Where Each One Suits
- 304 stainless steel for general outdoor exposure in non-coastal environments
- 316 stainless steel where salt air, road de-icing, or high humidity is present
- Mirror polish to reflect the surrounding space with clarity and precision
- Brushed finishing to reduce glare and hide handling marks from fabrication
- Painting where the design requires a non-reflective, coloured surface
Manufacturing Process
How the Part Is Made
- Scheme design against the site, which sets the form, size and finish
- Small model created and scaled up, with internal support structure designed in parallel
- Plaster mould taken from the model to shape the steel plate
- Plate forged to the mould and ground repeatedly to build the shell thickness
- Surface polished, brushed or sprayed to the final finish
- Welded assembly and final inspection before packing and shipping
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 invisible on the finished surface
- Repeated grinding before surface treatment ensures a smooth base
- Inner plastic or foam protection in the wooden crate prevents surface damage during transit
Customization
What Can Be Changed to Suit You
- Any diameter to specification; the company states stainless steel spheres from 25 mm to 10 m
- Mirror, brushed, painted or coloured finish applied to the same shell
- 304 or 316 body selected based on the site’s exposure conditions
- Ordered from a photograph or a drawing supplied by the customer
- Base and fixing detail designed to suit the installation site and load requirements
Comparison
How It Compares With the Alternatives
| A painted mild steel hemisphere | Painted mild steel is cheaper initially but requires repainting every few years; stainless steel maintains its finish permanently |
|---|---|
| A fiberglass hemisphere | Fiberglass is lighter and cheaper at large sizes but cannot be mirror polished and is better suited for indoor use |
| A corten steel hemisphere | Corten is chosen for its weathered, changing surface; this stainless steel form is chosen for a consistent, reflective appearance |
| A solid metal sphere | A hollow hemisphere reduces weight and material cost while maintaining visual presence at large scales |
Use Guide
Fitting and Running It
- Set the diameter against the space it will occupy, not against a catalogue size
- Place the hemisphere where it has something worth reflecting: sky, water, planting, or architecture
- Plan for a foundation and fixing detail sized for wind load, especially at larger diameters
- Clean a mirror surface with water and a soft cloth; avoid abrasives that damage the polish
- Specify 316 stainless steel if the site is coastal or exposed to winter de-icing salts
- Allow 25 to 30 days production time plus 15 to 20 days transport when scheduling the installation
Questions Buyers Ask
large metal spheres 24 large stainless steel hollow balls 100mm stainless steel ball Questions
What size is this stainless steel hemisphere and can it be made larger?
The listed size for this piece is 100 mm, and like most of this catalogue it is also made to custom size. The company states stainless steel spheres from 25 mm up to 10 m in diameter.
Which stainless grade will I get?
This hemisphere is made in #304 or #316 stainless steel. Tell us whether the site is coastal or salted in winter and we will confirm which grade suits the exposure.
Mirror, brushed or painted?
All three are available for this piece. Mirror gives the strongest reflection, brushed reduces glare and hides handling marks, and painting is used where the scheme wants colour instead.
How long from order to delivery for this hemisphere?
The listing states a production time of 25 to 30 days, with transport taking 15 to 20 days. Work back from the installation date to plan the order.
How is a polished hemisphere this size packed?
In an outer standard wooden crate with inner plastic or foam protection, which is what keeps the polished surface intact during transit.
Can you build one from a picture I have?
Yes. The workshop takes orders according to a photograph or a drawing from the customer. Send the reference image, the diameter you want and where it will stand.
