What This Piece Is
A custom round ball sculpture in corten (weathering) steel, fabricated to your specified size and shape using laser cutting and casting techniques. The surface develops a stable rust patina over time, giving it a natural, earthy appearance suited to outdoor gardens, plazas and landscape installations. Kapur Sculpture builds it from your photo, drawing or 3D file, and inspects it at every stage from production through to loading on the vessel, with digital pictures provided before shipment.
Key Benefits
- Corten steel develops a stable rust patina over time, reducing the need for painting or coating
- Made to your custom size and shape, not limited to fixed catalogue dimensions
- Laser cut and cast construction allows for intricate patterns and consistent detail
- Natural weathered appearance blends with planting and natural surroundings
- Built from your photo, drawing or 3D file so your design is reproduced accurately
- Inspected at each stage with digital photos sent before shipment
Buyers and Specifiers
- Landscape architects specifying a naturalistic sculpture for a masterplan
- Property and hotel developers commissioning outdoor art on a build programme
- Public art consultants managing municipal commissions with a natural materials theme
- Interior designers needing a large sculptural form for an outdoor atrium or terrace
- Sculpture galleries and importers sourcing large corten steel works from China
What It Fixes
- Fixed catalogue sizes rarely suit a real site so the piece is made to your dimension
- Painted steel fades and needs recoating while corten steel develops a stable patina
- Complex patterns are hard to reproduce by hand so laser cutting ensures precision
- Buyers cannot inspect an overseas factory so digital photos are supplied at each stage
- Large sculptures are damaged in transit so each piece ships in a wooden crate with foam or plastic lining
Where This Sculpture Is Installed
Garden and courtyard centrepieces where the sculpture is viewed up close and from all angles
Public plazas and civic spaces with a natural or organic aesthetic

How It Is Built
- Round ball form with custom diameter and height made to your drawing
- Laser cut and cast corten steel construction for consistent pattern and structural integrity
- Surface develops a stable rust patina over time, suitable for permanent outdoor exposure
- Internal structure supports the shell and maintains shape under weathering
- Any pattern or curvature reproduced from a supplied sample drawing or reference photo
- Base plate and anchoring detail prepared for the installation surface
Materials
- Corten steel selected for its ability to develop a stable rust patina in outdoor environments
- Internal steel frame or support structure to maintain shape and integrity
- Material grade confirmed with you before cutting rather than assumed
- Corten steel is not maintenance-free; surface will continue to weather over time

What You Can Change
- Overall diameter and height set to your drawing
- Choice of laser-cut pattern or custom design
- Base plate and fixing detail adapted to your foundation
- OEM and ODM orders accepted
- Coloured or coated variants not available on corten steel
- Any shape reproduced from a supplied sample drawing or reference photo
Ordering and Care
- Send the site dimensions, viewing distance and a reference photo or drawing when you enquire
- Confirm the installation location to assess exposure to rain, wind and salt if near coast
- Prepare a level concrete foundation matched to the base plate drawing supplied
- Allow crane access on the installation day for a large piece
- Avoid abrasive cleaning tools; rinse with water to remove salt deposits at coastal sites
- Expect the surface to change over time as the rust patina stabilises
How It Compares With Other Options
An honest read on the trade-offs, so the material decision is made before fabrication starts.
| Stainless steel sculpture | Stainless steel stays bright and reflective, while corten develops a natural rust patina that blends with nature |
|---|---|
| Fiberglass sculpture | Fiberglass is lighter and cheaper to ship and takes any colour, but it will not last as long outdoors as corten steel |
| Painted carbon steel | Painted steel costs less initially but needs recoating, whereas corten steel develops a stable patina without repainting |
| Bronze sculpture | Bronze develops a green patina over time and suits figurative work, while corten steel gives a warm, natural rust look for abstract forms |

Questions About This Sculpture
Can you make this in a size that is not listed?
Yes. Size is custom on this piece, and both diameter and height are made to your drawing. Send your dimensions and we will confirm feasibility and price.
How long does production and shipping take?
Production takes 25-30 days and ocean transport a further 15-20 days. Some items are held in stock, which shortens the production window.
Should I choose corten steel or stainless steel?
Choose corten steel for a natural, weathered look that blends with planting and terrain. Choose stainless steel for a bright, reflective surface that resists corrosion.
Can you work from my own design?
Yes. Orders are accepted from your photo or drawing, and OEM and ODM work is welcome. Send a 3D file, a sketch or detail pictures and our design team will work from it.
How is the sculpture packed for sea freight?
Each piece ships in an outer standard wooden crate with plastic or foam lining inside to protect the surface during handling.
Can I inspect the sculpture before it ships?
Yes. Our QC team inspects at all stages up to loading on the vessel and supplies digital pictures, and your own QC team is welcome to check quality in our factory.
Do you supply a certificate or load calculation?
Certification and structural documentation are confirmed per project. Tell us what your local authority requires when you send the enquiry.
