Stainless Steel Hemisphere
80mm stainless steel half sphere aisi 304/316/316L hemisphere
A half sphere in polished stainless steel is a compact, geometric form designed for placement in gardens, interior halls, or public spaces where a subtle reflective surface adds depth without dominating the site. This piece is a hollow hemisphere made from 304 or 316 stainless steel, with a mirror, brushed or painted finish. The listed size is 80 mm, and like almost every item in the catalogue, it is made to custom size on request. It is intended to stand as a standalone element or part of a larger composition, reflecting light and surrounding details in a controlled, clean way.

Key Benefits
What This Nozzle Gives You
- Hollow construction keeps weight low even at larger diameters
- Mirror, brushed or painted finish applied to the same shell for consistent appearance
- 304 for general indoor or sheltered outdoor use, 316 for coastal or high-moisture environments
- 80 mm as listed, or any diameter the site requires
- Wooden crate with inner plastic or foam packing protects the surface during transit
- Production time of 25 to 30 days, with transport taking 15 to 20 days
Application Scenarios
Where It Is Installed
- A garden feature where a small reflective form adds visual interest without blocking views
- An interior hall or lobby where a polished hemisphere catches light from above
- A public square with limited space for a full sphere but room for a half form
- A corporate reception area where a minimalist metal shape supports a modern aesthetic
- A film or VFX set where a reference hemisphere is needed for lighting or visual effects
Who It Is For
Buyers Who Specify It
- Landscape architects specifying a small reflective object in a tight garden space
- Interior designers placing a subtle metal form in a reception or corridor
- Art consultants sourcing a geometric reference piece for a set or installation
- Hotel developers commissioning a small but precise metal detail in a lobby
- Film or VFX teams needing a physical reference sphere for lighting or camera calibration
Problems It Solves
What It Fixes on the Line
- A small space that cannot accommodate a full sphere but needs a reflective object
- A site where a full sphere would be too large or too heavy for the foundation
- A need for a consistent reflective surface that does not change over time
- A project with a reference image but no technical drawing for a half sphere
- A requirement for a durable, low-maintenance metal form that resists corrosion
Technical Features
How It Is Built
- Hollow hemisphere formed from a single stainless steel plate over a mould
- Welded seam ground and polished to blend with the surrounding surface
- 304 or 316 stainless steel body depending on exposure conditions
- Mirror, brushed or painted finish applied after forming and polishing
- Custom diameter as standard, not as a special order
Materials
Body Materials and Where Each One Suits
- 304 stainless steel for indoor or sheltered outdoor use
- 316 stainless steel for coastal, salty, or high-moisture environments
- Mirror polish for a reflective surface that shows surroundings clearly
- Brushed finishing to reduce glare and hide minor surface marks
- Painting for colour application where reflection is not required
Manufacturing Process
How the Part Is Made
- Scheme design against the site, which sets form, size and finish
- Small model created and scaled up with internal support structure designed
- Plaster mould taken from the model for forming the hemisphere
- Steel plate forged to the mould and ground repeatedly to achieve the shape
- Surface polished or sprayed to the chosen finish
- Welded assembly and final inspection before packing
Quality Control
What Is Checked Before It Ships
- The company states it runs its own professional QC team
- Weld seam is ground and polished to blend with the surface
- Repeated grinding before final surface treatment is part of the published method
- Inner plastic or foam padding protects the surface inside the wooden crate
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
- 304 or 316 body to suit the exposure
- Ordered from a photograph or a drawing supplied by the customer
- Base and fixing detail worked out with the piece
Comparison
How It Compares With the Alternatives
| A painted mild steel hemisphere | Painted steel is cheaper but requires repainting; stainless holds its finish permanently |
|---|---|
| A full stainless steel sphere | A half sphere is lighter and easier to install in tight spaces, but shows less reflection |
| A fiberglass hemisphere | Fiberglass is lighter and cheaper but cannot be mirror polished and is not suitable for outdoor exposure |
| A corten steel hemisphere | Corten changes over time with weathering; this stainless version maintains a consistent surface |
Use Guide
Fitting and Running It
- Fix the diameter against the space it will occupy, not against a standard size
- Place the hemisphere where it has something to reflect: light, sky, wall, or floor
- Use 316 stainless steel if the site is near the sea or exposed to de-icing salts
- Clean the surface with water and a soft cloth; avoid abrasives that damage the polish
- Plan 25 to 30 days for production plus 15 to 20 days for transport from order date
- Specify the finish (mirror, brushed, painted) and material (304 or 316) at the time of ordering
Questions Buyers Ask
80mm stainless steel half sphere aisi 304/316/316L hemisphere Questions
What size is this half sphere and can it be made larger?
The listed size for this piece is 80 mm, and like most of this catalogue it is also made to custom size. The company states stainless steel hemispheres from 25 mm up to 10 m in diameter.
Which stainless grade will I get?
This half sphere is made in #304 or #316 stainless steel. Tell us whether the site is coastal or exposed to salt 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. Transport takes 15 to 20 days, so work back from the date the installation must be complete.
How is a polished hemisphere this size packed?
In a wooden crate with inner plastic or foam protection, on a Factory Direct and Door to Door Delivery basis, which keeps the 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.
