Stainless Steel Hemisphere
304 Stainless Steel Half Sphere Hemisphere
A half sphere or hemisphere is a finished, laconic geometric figure designed for placement in gardens, halls, or public squares. This piece is a hollow stainless steel hemisphere made from 304 or 316 stainless steel, with a mirror, brushed or painted finish. It is intended to stand as a standalone form or part of a larger composition, reflecting light and space in a way that gives the surrounding environment a subtle, mysterious quality. The listed size is custom size, and like almost every item in this catalogue, it is made to any diameter on request. Production time is 25 to 30 days, with transport taking 15 to 20 days.

Key Benefits
What This Nozzle Gives You
- A hollow hemisphere reduces weight at large sizes while maintaining structural integrity
- 304 or 316 stainless steel offers corrosion resistance suitable for indoor and outdoor use
- Mirror, brushed or painted finishes can be applied to the same shell, matching the design scheme
- Custom diameter as standard, not as a special order, allowing precise fit to the site
- Packed in an outer wooden crate with inner plastic or foam protection for transit
- Door to door delivery from factory ensures the polished surface arrives intact
Application Scenarios
Where It Is Installed
- A garden feature where a single hemisphere acts as a quiet focal point among planting
- An indoor hall where the curved surface reflects ceiling lights and architectural lines
- A public square where the hemisphere stands as a modern, minimalist object in an open space
- A hotel lobby where the piece reflects the entrance and guests walking past
- A corporate courtyard where the form reads against glass and paving
Who It Is For
Buyers Who Specify It
- Landscape architects specifying a minimalist geometric form for a garden or plaza
- Hotel and property developers commissioning a modern sculptural element for a lobby or forecourt
- Art consultants sourcing a precise hemisphere for a curated installation
- Interior designers placing a reflective form in a high-ceilinged space
- Municipal clients replacing a worn feature with a durable, low-maintenance sculpture
Problems It Solves
What It Fixes on the Line
- A space that needs a sculptural form but has no room for a full sphere or figurative piece
- A commission with only a reference image and no technical drawing
- A site that requires a durable, low-maintenance surface finish in outdoor or high-traffic areas
- A need for a form that reflects light and space without being overly decorative
- A project where the existing space demands a custom size, not one of three standard options
Technical Features
How It Is Built
- Hollow construction formed by shaping a steel plate over a mould and welding the edge
- Welded joint ground and polished to blend with the surrounding surface
- 304 or 316 stainless steel body selected based on environmental exposure
- Surface finish applied after forming: mirror, brushed or painted
- Custom diameter as standard, with no extra charge for non-standard sizes
Materials
Body Materials and Where Each One Suits
- 304 stainless steel for general indoor or outdoor use with moderate exposure
- 316 stainless steel for coastal environments or areas with road salt in winter
- Mirror polish to reflect the surrounding space with clarity
- Brushed finishing to reduce glare and hide handling marks
- Painting for schemes that require colour rather than reflective surface
Manufacturing Process
How the Part Is Made
- Scheme design against the site to determine placement, form and finish
- Small model created and scaled up with internal support structure designed
- Plaster mould taken from the model to shape the steel plate
- Steel plate forged to the mould and ground repeatedly to form the shell
- Surface polished, brushed or sprayed to final finish
- Welded assembly on site, with the joint finished to match the surrounding surface
Quality Control
What Is Checked Before It Ships
- The company states it runs its own professional QC team
- Welds are ground and polished to be invisible on the finished surface
- Repeated grinding before surface treatment ensures a smooth base
- Inner plastic or foam protection prevents scratches during transit
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 applied to the same shell
- 304 or 316 body selected based on the exposure environment
- Ordered from a photograph or a drawing supplied by the customer
- Base and fixing detail designed to match the installation site
Comparison
How It Compares With the Alternatives
| A full stainless steel sphere | A hemisphere is lighter and easier to install at large sizes, and it can be placed to face a specific view or light source |
|---|---|
| A painted mild steel hemisphere | Painted steel costs less initially but requires repainting; stainless holds its finish permanently |
| A corten steel hemisphere | Corten is chosen for its weathered appearance; this piece is chosen for a clean, reflective surface that does not change |
| A fiberglass hemisphere | Fiberglass is lighter and cheaper but cannot be polished to a mirror finish and is not suitable for outdoor exposure |
Use Guide
Fitting and Running It
- Choose the diameter based on the space it will occupy, not on a standard size
- Place the hemisphere where it has something to reflect: sky, planting, or architectural detail
- Ensure the base and fixing are sized for wind load, especially at larger diameters
- Clean mirror surfaces 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 in winter
- Plan 25 to 30 days for production plus 15 to 20 days for transport from the installation date
Questions Buyers Ask
304 Stainless Steel Half Sphere Hemisphere Questions
What size is this half sphere and can it be made larger?
The listed size for this half sphere is custom size, and like most of this catalogue it is made to any diameter on request. The company states stainless steel spheres 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 salted in winter and we will confirm which grade suits the exposure.
Mirror, brushed or painted?
All three finishes 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.
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 site needs to be ready.
How is this hemisphere packed?
In an outer standard wooden crate with inner protection in plastic or foam, 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.
