Stainless Steel Hemisphere
Large solid metal sphere of 304 stainless steel balls from factory
A hollow stainless steel sphere is designed for outdoor placement in gardens, parks, or public squares, where it acts as a striking focal point. The surface is mirror polished, reflecting the sky, surrounding greenery, and passing people. Made from 304 or 316 stainless steel, the piece is built to any custom diameter and is intended for permanent outdoor installation. The listed production time is 25 to 30 days, with transport taking 15 to 20 days after production.

Key Benefits
What This Nozzle Gives You
- Mirror polish creates a reflective surface that changes with light and time of day
- Hollow construction reduces weight at large sizes while maintaining structural integrity
- 304 or 316 stainless steel offers corrosion resistance for long-term outdoor use
- Custom diameter available to fit the exact space, not the other way around
- Standard wooden crate with inner plastic or foam packing protects the surface during transit
- Factory Direct and Door to Door Delivery ensures the piece arrives with minimal risk
Application Scenarios
Where It Is Installed
- A garden or park where a single object needs to draw attention without dominating the landscape
- A public square where a reflective sphere enhances the sense of space and movement
- A hotel entrance or commercial plaza where the sphere serves as a modern landmark
- A corporate campus or public art installation where durability and clean lines are required
- An outdoor courtyard where the sphere reflects the architecture and natural elements
Who It Is For
Buyers Who Specify It
- Landscape architects specifying a permanent reflective object in a public space
- Property developers commissioning a durable, low-maintenance sculpture for a residential or commercial site
- Art consultants sourcing a contemporary metal sphere with consistent finish and scale
- Garden designers integrating a modern sculptural element into a green space
- Film or VFX teams needing a reference sphere for visual effects with a consistent reflective surface
Problems It Solves
What It Fixes on the Line
- A public space that lacks a visual anchor despite being open and paved
- A garden or courtyard that needs a modern sculptural feature but has no room for large figurative work
- A project that requires a mirror surface but cannot use glass due to safety or durability concerns
- A commission with no technical drawing but a clear visual reference that must be replicated
- A need for a long-lasting sculpture that does not require repainting or surface maintenance
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 polish applied to the entire shell after welding and grinding
- Custom diameter as standard, not as a special order, with no fixed size listed
- Packing in a wooden crate with inner plastic or foam to protect the polished surface
Materials
Body Materials and Where Each One Suits
- 304 stainless steel for general outdoor use in non-coastal environments
- 316 stainless steel for coastal areas or locations where de-icing salts are used
- Mirror polish that reflects the surrounding environment with high clarity
- Plastic or foam lining inside the wooden crate to prevent surface damage
- Hollow construction that reduces weight while maintaining structural strength
Manufacturing Process
How the Part Is Made
- Scheme design based on the intended site and visual impact
- Small model created and scaled up with internal support structure designed
- Plaster mould taken from the model to form the hemispheres
- Steel plate forged to the mould and ground repeatedly to build the shell
- Surface polished to mirror finish after welding and grinding
- Welded assembly and final inspection before packing and delivery
Quality Control
What Is Checked Before It Ships
- The company states it runs its own professional QC team
- Weld joint is ground and polished to be flush with the shell surface
- Repeated grinding before polishing ensures a smooth base for the mirror finish
- Packing with plastic or foam inside the wooden crate protects the surface during transit
Customization
What Can Be Changed to Suit You
- Any diameter to specification, with no standard size listed
- Mirror polish, brushed finish, or painted surface available on the same shell
- 304 or 316 stainless steel selected based on site exposure
- Orders accepted from a photograph or a drawing supplied by the customer
- Base and fixing detail designed in coordination with the installation site
Comparison
How It Compares With the Alternatives
| A painted mild steel sphere | Painted steel is cheaper initially but requires repainting every few years; stainless steel maintains its finish without maintenance |
|---|---|
| A fiberglass sphere | Fiberglass is lighter and cheaper at large sizes but cannot be polished to a mirror finish and is not suitable for permanent outdoor use |
| A corten steel sphere | Corten is chosen for its weathered, changing surface; this mirror sphere is chosen for a consistent, reflective appearance |
| A solid metal sphere | Solid spheres are heavier and more expensive to produce; this hollow version reduces weight and cost while maintaining visual impact |
Use Guide
Fitting and Running It
- Choose the diameter based on the space it will occupy, not on a standard size
- Place the sphere where it has a clear view of sky, planting, or architecture to reflect
- Ensure the foundation and fixing are sized for wind load at large diameters
- Clean the mirror surface with water and a soft cloth; avoid abrasives that damage the polish
- Specify 316 stainless steel if the site is near the coast or exposed to road salt in winter
- Plan 25 to 30 days for production and 15 to 20 days for transport after order confirmation
Questions Buyers Ask
Large solid metal sphere of 304 stainless steel balls from factory Questions
What size is this metal sphere and can it be made larger?
This piece is made to custom size, with no standard diameter listed. The company states stainless steel spheres from 25 mm to 10 m in diameter, so it can be made to any size required.
Which stainless steel grade will I get?
This sphere is made in 304 or 316 stainless steel. If the site is coastal or exposed to de-icing salts, we recommend 316 for better corrosion resistance.
Mirror, brushed or painted finish?
The surface can be mirror polished, brushed, or painted. Mirror gives the strongest reflection, brushed reduces glare, and painting is used when colour is needed.
How is the sphere packed for shipping?
It is packed in an outer standard wooden crate with inner plastic or foam to protect the polished surface during transit.
Can you make one from a photo I have?
Yes. The workshop takes orders from a photograph or a drawing supplied by the customer. Send the image, desired diameter, and installation location.
