Stainless Steel Sculpture
Large City Square Stainless Steel Balloon Outdoor Sculpture 3-9 Meters are available
A large stainless steel balloon sculpture is designed for a city square or public space where scale and reflection define the character of the environment. This hollow spherical form, made from 304 or 316 stainless steel, stands between 3 and 9 meters in diameter and is intended to anchor an open paved area with a continuous reflective surface. The listed size range is 3 to 9 meters, and like almost every piece in this catalogue, it is made to any size within that range on request. The surface is mirror polished, brushed, or painted, and the production window is 25 to 30 days, with transport taking 15 to 20 days after production.

Key Benefits
What This Nozzle Gives You
- A large reflective surface captures sky, buildings, and movement, making the space feel dynamic at all times
- Hollow construction reduces weight at large diameters, simplifying foundation and installation
- 304 for general urban exposure or 316 where coastal air or winter deicing is present
- Mirror, brushed, or painted finish from the same shell ensures consistent surface treatment
- 3 to 9 meters as listed, or any diameter within that range on request
- Standard wooden crate with inner plastic or foam packing protects the surface during transit
Application Scenarios
Where It Is Installed
- A city square where a single large object must define the centre of a wide open space
- A public plaza that needs a landmark with visual impact from all approach angles
- A civic park entrance where the sculpture is seen before the building or gate
- A commercial district forecourt where the reflective form interacts with glass and steel
- A waterfront area where the sphere reflects water, sky, and passing people
Who It Is For
Buyers Who Specify It
- Landscape architects designing a focal point for a large public square
- Urban design studios commissioning a permanent sculpture for a civic space
- Property developers needing a landmark for a mixed-use development
- Art consultants sourcing a large-scale reflective piece for a public installation
- Municipal clients replacing a worn or outdated centrepiece in an existing plaza
Problems It Solves
What It Fixes on the Line
- A large open square with no visual anchor and no sense of scale
- A public space that lacks a permanent feature to define its identity
- Off-the-shelf sculptures that come in only three sizes, none of which fit the site
- A commission with a reference photo but no technical drawing or dimensions
- A need for a durable, low-maintenance surface that does not require repainting
Technical Features
How It Is Built
- Hollow shell formed from two hemispheres over a mould and welded together
- Weld joint ground and polished to be invisible on the finished surface
- 304 or 316 stainless steel body depending on exposure conditions
- Mirror, brushed, or painted finish applied to the same shell for consistency
- Custom diameter within the 3 to 9 meter range as standard, not as a special order
Materials
Body Materials and Where Each One Suits
- 304 stainless steel for general urban outdoor exposure
- 316 stainless steel where coastal air or winter road salt is present
- Mirror polish for a full reflection of the surrounding environment
- Brushed finishing to reduce glare and hide minor handling marks
- Painting where the design calls for colour rather than reflective surface
Manufacturing Process
How the Part Is Made
- Scheme design against the site to determine form, scale, and finish
- Small clay model scaled up with internal support structure designed in parallel
- Plaster mould taken from the model to form the shell
- Steel plate forged to the mould and ground repeatedly to build the shell
- Surface polished, brushed, or sprayed after welding and grinding
- Welded assembly and installation on site, with joint finished in place
Quality Control
What Is Checked Before It Ships
- The company states it runs its own professional QC team
- Weld between hemispheres is ground and polished to be invisible
- Repeated grinding before surface treatment is part of the published method
- Inner plastic or foam protection inside the wooden crate prevents surface damage
Customization
What Can Be Changed to Suit You
- Any diameter between 3 and 9 meters, with no additional cost for custom size
- Mirror, brushed, or painted finish applied to the same shell
- 304 or 316 stainless steel selected based on site exposure
- Ordered from a photograph or a drawing supplied by the customer
- Base and fixing detail designed to suit the site and wind load
Comparison
How It Compares With the Alternatives
| A painted mild steel sculpture | Painted steel is cheaper initially but requires repainting every few years; stainless steel maintains its finish permanently |
|---|---|
| A concave mirror piece | A concave surface distorts and inverts reflections at close range, while a full sphere reads clearly from all distances |
| A fiberglass sculpture | Fiberglass is lighter and cheaper at large sizes but cannot be polished to a mirror finish and is not suited for outdoor exposure |
| A corten steel sculpture | Corten is chosen for its weathered, changing surface; this piece is chosen for a consistent, reflective finish that does not change |
Use Guide
Fitting and Running It
- Set the diameter against the scale of the square, not against a catalogue size
- Place the sculpture where it has something worth reflecting: sky, water, building facades
- Allow for a foundation and fixing detail 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 experiences winter deicing
- Plan 25 to 30 days production plus 15 to 20 days transport from the installation date
Questions Buyers Ask
Large City Square Stainless Steel Balloon Outdoor Sculpture 3-9 Meters are available Questions
What size is this balloon sculpture and can it be made larger?
The listed size range for this piece is 3 to 9 meters, and like most of this catalogue it is also made to any size within that range on request. The company states stainless steel spheres from 25 mm to 10 m in diameter.
Which stainless grade will I get?
This balloon sculpture is made in #304 or #316 stainless steel. Tell us whether the city square 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 instead.
How long from order to delivery for this balloon sculpture?
The listing states a production time of 25 to 30 days. Transport takes 15 to 20 days after production, so work back from the date the square has to be finished.
How is a polished sculpture this size packed?
In an outer standard wooden crate with inner plastic or foam protection, on a Factory Direct and Door to Door Delivery basis, which keeps the polished 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.
