Stainless Steel Hemisphere
304 large metal sphere Stainless Steel Half Sphere Hemisphere
A half sphere made from stainless steel is a clean, geometric form that stands as a focal point in a garden, a public square, or an interior space. This piece is a hollow hemisphere formed from 304 or 316 stainless steel, designed to reflect its surroundings with a mirror, brushed or painted surface. The listed size is custom size, and like almost every item in this catalogue, it is made to any diameter on request. The body is formed over a mould, welded at the base, and finished to a smooth surface. It is built for outdoor or indoor installation where a strong, permanent form is needed.

Key Benefits
What This Nozzle Gives You
- A hollow hemisphere reduces weight while maintaining structural integrity at large sizes
- 304 or 316 stainless steel resists corrosion and holds its finish in outdoor environments
- Mirror, brushed or painted finishes can be applied to the same shell, matching the design scheme
- Custom diameter on request allows the piece to fit precisely within a given space
- Wooden crate packing with inner plastic or foam protects the surface during transit
- Production time of 25 to 30 days allows for planning within a standard project timeline
Application Scenarios
Where It Is Installed
- A garden entrance where a single hemisphere acts as a subtle but strong threshold marker
- A public square where the form stands as a modern, reflective object without figurative distraction
- An interior atrium or hotel lobby where the hemisphere reflects light and architecture
- A corporate courtyard where the piece reads as a contemporary, minimalist statement
- A landscape feature where the hemisphere is placed to reflect sky, trees or building lines
Who It Is For
Buyers Who Specify It
- Landscape architects specifying a geometric form for a paved or planted space
- Property developers commissioning a durable, low-maintenance feature for a residential or commercial site
- Hotel designers placing a sculptural object in a reception area or courtyard
- Art consultants sourcing a modern, non-figurative piece with a reflective surface
- Interior designers integrating a metal form into a contemporary interior with clean lines
Problems It Solves
What It Fixes on the Line
- A space that lacks a defined focal point but cannot accommodate a full sphere
- A commission that needs a geometric form but has no technical drawing or model
- A site where a painted or mild steel piece would degrade over time
- A project with a tight schedule that needs a piece made in 25 to 30 days
- A need for a form that reflects its environment without distortion or visual clutter
Technical Features
How It Is Built
- Hollow hemisphere formed by shaping a stainless steel plate over a mould
- Welded at the base edge, with the joint ground and finished to match the surface
- 304 or 316 stainless steel body depending on environmental exposure
- Mirror, brushed or painted finish applied to the same shell for consistency
- Custom diameter as standard, not as a special order, with no fixed size listed
Materials
Body Materials and Where Each One Suits
- 304 stainless steel for general outdoor use in non-coastal areas
- 316 stainless steel for environments with salt air, road de-icing, or high humidity
- Mirror polish for strong reflection of sky, landscape or architecture
- Brushed finishing to reduce glare and hide minor surface marks
- Painting for colour integration where reflection is not required
Manufacturing Process
How the Part Is Made
- Scheme design against the site to determine form, size and finish
- Small model created and scaled up with internal support structure designed
- Plaster mould taken from the model to shape the hemisphere
- Steel plate forged to the mould and ground repeatedly to form the shell
- Surface polished, brushed or sprayed to final finish
- Welded assembly and installation detail worked out with the piece
Quality Control
What Is Checked Before It Ships
- The company states it runs its own professional QC team
- Welds are ground and finished to match the surface, not left proud
- Repeated grinding before surface treatment ensures a smooth base
- Inner plastic or foam protection in the wooden crate prevents surface damage
Customization
What Can Be Changed to Suit You
- Any diameter to specification; the company states spheres from 25 mm to 10 m in diameter
- Mirror, brushed or painted finish applied to the same shell
- 304 or 316 stainless steel chosen based on site exposure
- Ordered from a photograph or a drawing supplied by the customer
- Base and fixing detail designed to suit the installation site
Comparison
How It Compares With the Alternatives
| A full stainless steel sphere | A hemisphere is lighter and easier to transport and install; it holds a reflective surface while reducing material use and weight |
|---|---|
| A painted mild steel hemisphere | Painted mild steel is cheaper but requires repainting; stainless steel maintains its finish permanently |
| A corten steel hemisphere | Corten changes over time with weathering; this piece holds a consistent surface, chosen for permanence and reflection |
| A fiberglass hemisphere | Fiberglass is lighter and cheaper but cannot be mirror polished and is not suitable for long-term outdoor exposure |
Use Guide
Fitting and Running It
- Choose the diameter based on the space around it, not on a standard size
- Place the hemisphere where it has something to reflect: sky, water, planting, or building
- Ensure the base and fixing detail are 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 stainless steel if the site is coastal or exposed to road salt
- Plan 25 to 30 days production plus 15 to 20 days transport from the installation date
Questions Buyers Ask
304 large metal sphere Stainless Steel Half Sphere Hemisphere Questions
What size is this hemisphere and can it be made larger?
This hemisphere is made to custom size, with no standard dimension listed. The company states stainless steel spheres from 25 mm to 10 m in diameter, so any size can be built.
Which stainless steel grade will I get?
This hemisphere is made in 304 or 316 stainless steel. Tell us whether the site is coastal or exposed to salt in winter, and we will confirm the best grade for your location.
Mirror, brushed or painted finish?
All three finishes are available for this piece. Mirror gives the strongest reflection, brushed reduces glare and hides marks, and painting is used when colour is needed.

It is packed in an outer standard wooden crate with inner plastic or foam protection to prevent surface damage 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 desired diameter, and the intended location.
