Key Benefits
What This Nozzle Gives You
- Mirror polish enhances visual impact by reflecting sky, landscape, and people in a continuous curved surface
- Brushed finish reduces glare and hides handling marks while maintaining a modern aesthetic
- Hollow construction reduces weight at large diameters, easing installation and foundation design
- 304 for general outdoor use or 316 for coastal or high-salt environments
- Custom size as standard, not a special order, allowing fit to exact site dimensions
- Wooden crate with inner plastic or foam packing protects the surface during transit
Application Scenarios
Where It Is Installed
- A public square where a single reflective object anchors the open space and draws attention
- An apartment or hotel forecourt needing a minimalist yet striking landmark
- A garden path or courtyard where the sphere reflects planting, sky, and architecture
- A commercial plaza where the sculpture complements modern architecture and glass facades
- An outdoor art installation where the piece interacts with changing light throughout the day
Who It Is For
Buyers Who Specify It
- Landscape architects specifying a focal point in a paved or open outdoor area
- Hotel and property developers commissioning a durable, low-maintenance sculpture
- Art consultants sourcing a contemporary, reflective form for a public or private site
- Urban design studios integrating a polished metal object into a modern streetscape
- Private collectors interested in a large-scale, custom-made outdoor sculpture
Problems It Solves
What It Fixes on the Line
- An open outdoor space that lacks a visual anchor or focal point
- A site where off-the-shelf spheres do not match the required scale or finish
- A need for a durable, long-term sculpture that does not require repainting or maintenance
- A project with a reference image but no technical drawing, requiring fabrication from visual input
- A desire for a sculpture that changes appearance with the time of day and weather conditions
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 or brushed finish applied to the entire shell for consistent appearance
- Custom diameter as standard, not a special order, with no fixed size limit
Materials
Body Materials and Where Each One Suits
- 304 stainless steel for general outdoor exposure with no salt or coastal influence
- 316 stainless steel for environments with coastal air, road salt, or high humidity
- Mirror polish for maximum reflection and visual impact under sunlight
- Brushed finish for reduced glare and a softer, tactile surface appearance
- Hollow construction to reduce weight while maintaining structural integrity
Manufacturing Process
How the Part Is Made
- Scheme design developed in relation to the site, including form, scale, and finish
- Small model created and scaled up with internal support structure designed in parallel
- Plaster mould taken from the model to form the hemispheres
- Steel plate forged to the mould and ground repeatedly to shape the shell
- Surface polished to mirror or brushed finish, depending on the specification
- Welded assembly and final finishing performed on-site to ensure the joint is seamless
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 flush with the surface, not raised
- Repeated grinding before polishing ensures a smooth, defect-free finish
- Inner plastic or foam padding in the wooden crate protects the surface during transit
Customization
What Can Be Changed to Suit You
- Any diameter to specification, with no fixed size limit beyond the listed custom size
- Mirror polish or brushed finish applied to the entire shell
- 304 or 316 stainless steel selected based on site exposure conditions
- Orders accepted from a photograph or technical drawing provided by the customer
- Base and fixing details designed in coordination with the installation site
Comparison
How It Compares With the Alternatives
| Painted mild steel sculpture | Painted steel is cheaper initially but requires repainting every few years; stainless steel maintains its finish permanently |
|---|---|
| Fiberglass sphere | Fiberglass is lighter and less expensive at large sizes but cannot be polished to a mirror finish and is not suitable for long-term outdoor exposure |
| Corten steel sculpture | Corten is chosen for its weathered, rusted appearance over time; this mirror sphere is chosen for a clean, reflective surface that does not change |
| Bronze sculpture | Bronze develops a patina over time and requires maintenance; stainless steel retains its original finish without change |
Use Guide
Fitting and Running It
- Select the diameter based on the scale of the surrounding space, not on a catalogue size
- Place the sphere where it has a meaningful reflection—sky, trees, building facades, or water
- Ensure the foundation and fixing system are designed for wind load, especially at larger 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 de-icing
- Plan 25 to 30 days for production plus 15 to 20 days for transport from the order date
