Key Benefits
What This Nozzle Gives You
- Hollow construction reduces weight while maintaining structural integrity at large diameters
- 304 stainless steel for general outdoor use or 316 where exposure to salt or moisture is expected
- Surface finish can be left in original metal or custom painted to match a design scheme
- 50 cm as listed, or any diameter the site requires, with no standard size limiting the fit
- 15 to 30 days production after deposit, enabling tighter project scheduling
- Wooden case packing and door to door delivery protect the surface during transit
Application Scenarios
Where It Is Installed
- A private garden where a single reflective object adds visual interest without blocking views
- A public plaza that needs a central feature without the bulk of a figurative sculpture
- A hotel courtyard where the sphere reflects the building facade and garden planting
- A residential entrance where the piece acts as a landmark visible from the street
- A landscape design where the sphere’s reflection enhances the sense of space and light
Who It Is For
Buyers Who Specify It
- Landscape architects specifying a reflective object for a garden or open space
- Property developers commissioning a durable, low-maintenance feature for a residential project
- Hotel and resort designers placing a sculptural element in an arrival area
- Art consultants sourcing a contemporary metal sphere with flexible size and finish options
- Private collectors looking for a modern, minimalist piece for an outdoor installation
Problems It Solves
What It Fixes on the Line
- A garden that lacks a focal point but cannot accommodate a large figurative sculpture
- A public space needing a durable, maintenance-free object that does not require repainting
- A project with a reference image but no technical drawing, requiring a custom build
- A site where the existing space does not match standard off-the-shelf sphere sizes
- A design that requires a reflective surface but must avoid the visual clutter of painted or textured finishes
Technical Features
How It Is Built
- Hollow shell formed from two hemispheres welded together over a mould
- Weld joint ground and polished to blend with the surrounding surface
- 304 or 316 stainless steel body, selected based on environmental exposure
- Shell thickness between 1.0 and 3.0 mm, balancing strength and weight
- Surface finish available in original stainless steel or custom colour
- Custom diameter as standard, not as a special order
Materials
Body Materials and Where Each One Suits
- 304 stainless steel for general outdoor use in non-coastal or low-salt environments
- 316 stainless steel for sites exposed to coastal air, road salt, or de-icing chemicals
- Original stainless steel finish for a reflective, clean surface that ages minimally
- Custom colour finish for schemes requiring a specific hue rather than mirror reflection
- 1.0 to 3.0 mm shell thickness, selected to suit the size and structural needs
Manufacturing Process
How the Part Is Made
- Scheme design against the site, including placement, size, and finish
- Small model created and scaled up to the final size with internal support details
- Plaster mould taken from the model for forming the hemispheres
- Steel plate forged to the mould and ground repeatedly to shape the shell
- Surface treated with polishing or custom painting after welding and grinding
- Welded assembly and final finish completed before packing and delivery
Quality Control
What Is Checked Before It Ships
- The company states it runs its own professional QC team
- Welds are ground and polished to match the surrounding surface, not left raised
- Repeated grinding is part of the process to ensure a smooth finish before treatment
- Wooden case packing protects the surface during shipping and handling
Customization
What Can Be Changed to Suit You
- 304 or 316 stainless steel body based on site exposure
- Original stainless steel finish or custom colour applied to the same shell
- Ordered from a photograph or a drawing supplied by the customer
- Base and fixing detail designed in coordination with the piece and 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 holds its finish permanently |
|---|---|
| A fibreglass sphere | Fibreglass is lighter and cheaper at large sizes but cannot be polished to a mirror finish and is not suitable for outdoor exposure |
| A corten steel form | Corten is chosen for its weathered, changing surface; this sphere is chosen for a consistent, reflective appearance |
| A bronze sculpture | Bronze develops a patina over time; this stainless steel sphere maintains its original surface without change |
Use Guide
Fitting and Running It
- Fix the diameter against the space around it, not against a catalogue size
- Place the sphere where it has something to reflect: sky, trees, building façades
- Use 316 stainless steel if the site is near the coast or experiences winter salting
- Clean the surface with water and a soft cloth; avoid abrasives that damage the finish
- Plan 15 to 30 days production after deposit, plus sea freight time from the installation date
- Ensure the base and fixing detail are sized for wind load at larger diameters
Questions Buyers Ask
stainless steel sphere 20 inch hollow metal sphere stainless steel Large outdoor garden ornament hollow sphere 50cm Questions
What size is this stainless steel sphere and can it be made larger?
The listed size for this piece is 50 cm, and like most of this catalogue it is also made to custom size.
Which stainless grade will I get?
This sphere is made in #304 or #316 stainless steel. Tell us whether the garden is near the coast or exposed to salt in winter and we will confirm which grade suits the exposure.
Original finish or custom colour?
This piece is available in the original stainless steel finish or custom colour. The original finish gives a reflective surface; custom colour is used where the design calls for a specific hue.
How long from deposit to delivery for this sphere?
The listing states a production time of 15 to 30 days after deposit. Sea freight is on top of that, so work back from the installation date.
How is a polished sphere this size packed?
In a wooden case, on a Factory Direct and Door to Door Delivery basis, which is what keeps a polished surface intact between the workshop and the site.
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.
