Product Overview

What This Piece Is

A round water portal sculpture in corten (weathering) steel, built to your custom size and shape rather than a fixed catalogue dimension. The form is constructed as a welded shell over an internal frame, then left to develop a stable rust patina naturally over time. Because corten steel forms a protective oxide layer that resists further corrosion, the piece maintains structural integrity in outdoor environments without requiring paint or coating. Kapur builds it from your photo, drawing or 3D file, and inspects it at every stage from fabrication through to loading on the vessel.

Key Benefits

  • Made to your custom size and curvature so it fits the exact dimensions of your site
  • Corten steel develops a natural rust patina that stabilises over time and resists further corrosion
  • No paint or coating required—patina forms naturally in outdoor exposure
  • Built from your photo, drawing or 3D file so your design concept is realised directly
  • Inspected at each production stage with digital photos sent before shipment
  • Shipped in a standard wooden crate with plastic or foam lining to survive ocean freight
Who It Is For

Buyers and Specifiers

  • Landscape architects specifying a water feature with a natural, aged appearance
  • Property and hotel developers commissioning a unique entrance element with low maintenance
  • Public art consultants managing outdoor installations in moderate climates
  • Interior designers integrating a large water feature into a courtyard or atrium
  • Sculpture galleries and importers sourcing weathered steel art from China
Problems It Solves

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 naturally
  • Welded seams on curved forms often show under light so joints are ground back and left to age uniformly
  • 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

Manufacturing Process

How We Make It

  • Confirm the form from your photo, drawing or 3D file and agree final dimensions
  • Build the internal frame and set out the portal geometry
  • Cut and form the corten steel panels to the developed surface
  • Weld the shell to the frame section by section
  • Leave the surface untreated so the natural patina develops over time
  • Inspect, photograph and crate for ocean freight
Quality Control

How It Is Checked

  • Kapur runs its own QC team rather than relying on the fabrication crew to sign off their work
  • Inspection at all stages from production up to loading on vessel
  • Digital pictures supplied at each stage so you can approve before the next step
  • Weekly reports during the production window
  • Your own QC team or third party inspector is welcome to check quality in our factory

Certifications

No certification is claimed for this piece because none is documented on our source records. Tell us what your local authority or main contractor requires and we will confirm per project before you order.

5

Inspection

Our QC team checks each stage and sends digital pictures

6

Crating

Outer wooden crate, inner plastic or foam, then loading on vessel

Customization Options

What You Can Change

  • Overall height and curvature set to your drawing
  • Choice of corten steel for a natural rusted finish
  • Water flow system designed to match your portal shape
  • Base plate and fixing detail adapted to your foundation
  • OEM and ODM orders accepted
  • Coloured or coated variants not applicable—corten steel develops patina naturally
Use Guide

Ordering and Care

  • Send the site dimensions, viewing distance and a reference photo or drawing when you enquire
  • Confirm the location and exposure to rain and wind to ensure the patina develops as expected
  • Prepare a level concrete foundation matched to the base plate drawing supplied
  • Allow crane access on the installation day for a tall piece
  • Avoid abrasive cleaning tools—rinse with water and wipe with a soft cloth to maintain surface
  • Rinse more often in coastal or high-rainfall areas to prevent salt or mineral deposits
Comparison

How It Compares With Other Options

An honest read on the trade-offs, so the material decision is made before fabrication starts.

Stainless steel sculptureStainless steel stays bright and reflective, while corten steel develops a warm, natural rust tone suited to gardens and nature
Fiberglass sculptureFiberglass is lighter and takes any colour, but corten steel is more durable and weather-resistant in outdoor conditions
Painted carbon steelPainted steel requires recoating; corten steel forms a protective layer that lasts without maintenance
Bronze sculptureBronze develops a green patina over time and is heavier; corten steel is more cost-effective and forms a rust patina faster
FAQ

Questions About This Sculpture

Can you make this in a size that is not listed?

Yes. Size is custom on this piece, and both curvature 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?

Corten steel develops a natural rust patina and suits gardens and outdoor settings. Stainless steel stays bright and is better for reflective or modern designs.

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.
