Corten Steel Sculpture and How the Patina Really Behaves
What weathering steel does over its first years outdoors, what it does to the paving underneath, and what to detail at design stage.
Corten Steel Sculpture
CORTEN Steel Water Bowl
CORTEN Steel Water Bowl is a Corten weathering steel water feature built to order in our Shenzhen workshop.
Product Overview
What This Piece Is
CORTEN Steel Water Bowl is a Corten weathering steel water feature built to order in our Shenzhen workshop.
A water feature adds sound as well as sight, which is what makes a courtyard feel separated from the street beyond it.
Corten steel is alloyed so that the first layer of rust seals the plate underneath instead of eating into it, which is why the colour settles rather than keeps spreading.
The minimum order is one piece, the size is set by your drawing rather than by a catalogue.

Key Benefits
Why Buyers Specify This Piece
- Made from Corten weathering steel, which develops its own protective rust patina and never needs painting.
- Height, width and base detail for this water feature are set from your drawing, so it is proportioned to the space instead of being the nearest standard size.
- One water feature is a full order. A single project in gardens and courtyards does not have to wait for a container quantity.
- A water feature adds sound as well as sight, which is what makes a courtyard feel separated from the street beyond it.
- Anything about this water feature that has to change for gardens and courtyards is settled on the drawing, where changes still cost nothing.
- Fixing points and the anchor pattern for this water feature are drawn before fabrication, so site work is bolt down rather than improvisation.
Application Scenarios
Where It Is Installed
Set on a lawn, in a planting bed or on a courtyard paving grid, on a concrete pad or a levelled base plate.
Who It Is For
The People Who Order This
- Property developers placing a Corten steel water feature in gardens and courtyards to anchor an arrival point
- Hotel and hospitality groups adding a water feature to gardens and courtyards without closing the space for a refurbishment
- Public art planners and municipal teams siting a water feature in gardens and courtyards where it will take public contact
- Galleries and trade buyers reselling Corten steel water features into their own local projects
Problems It Solves
What This Piece Removes From the Project
- Architects want a warm, earth toned mass in a landscape without committing to a repainting cycle. Corten gives that without a coating system.
- Freight damage to a finished surface is the most common way a water feature project goes wrong. The crate is built around the geometry rather than bought as a standard box.
- A water feature specified late has to fit dimensions that are already fixed. Working from your drawing means the piece adapts instead of the scheme.
- Suppliers who subcontract the finishing cannot answer for the surface. The Corten weathering steel here is cut, welded and finished under one roof.
Technical Features
How It Is Constructed
- Internal pipework, pump chamber and drainage detailed into the form rather than added afterwards
- Fabricated throughout in Corten weathering steel with matching filler where the material is welded
- Panel divisions set out from a developed flat pattern so the Corten steel meets without being forced
- Edges and arrises detailed for the contact a water feature gets in gardens and courtyards

Materials
What It Is Made From
- Corten weathering steel
- Stainless or galvanised fixings sized for this water feature and supplied with it
Manufacturing Process
How It Is Made
1
Plate cutting to the cutting list
2
Press forming and rolling of the plate sections
3
Full penetration welding of the structural seams
4
Grinding of welds so the patina forms evenly across them
5
Accelerated weathering so the piece ships already coloured
6
Internal drainage checks and base plate fitting
Quality Control
What Is Checked and When
- Plate thickness checked against the drawing
- Structural welds inspected before weathering
- Patina evenness reviewed across panels and weld lines
- Drainage and vent holes confirmed open
- Base plate hole pattern checked against the foundation drawing
Customisation Options
What Can Be Changed
- Overall height, width and depth of the water feature set from your drawing or from the dimensions of gardens and courtyards
- Lighting designed into the water feature with the cable route concealed
- Your own branding applied to the water feature for resale as OEM or ODM work
- The Corten steel grade stepped up where the piece is going within reach of salt or treated water
Comparison
How It Compares With the Alternatives
Compared with Painted steel in a rust colour
A rust coloured paint film is an imitation that fades and peels. Corten is the real oxide layer and goes on deepening instead of failing.
Compared with A cast or moulded reproduction
A reproduction repeats a fixed size. This water feature is built to your dimensions, which is the whole reason to commission one.
Compared with Buying through a trading company
A trader passes drawings along and adds a margin. Here the water feature is drawn and built by the same people you are talking to.
Use Guide
Looking After It Once It Is Installed
- Let the patina continue to settle for the first year on site
- Keep the base clear so water drains away instead of pooling
- Expect run off staining on pale paving and detail a gravel or dark stone margin
- Do not seal the surface unless a sealed look was agreed at the design stage

How to Choose the Right Size for a Garden Sculpture
The single most common regret is a piece that is too small. Here is how to get the scale right before anything is fabricated.

The base plate and the anchor pattern cause more delays on site than anything else. They are also the easiest part to get right in advance.
Frequently Asked Questions
Can this be made in a different size
Yes. CORTEN Steel Water Bowl is made to order, so the height and width are set from your drawing or from the dimensions of the space. Send the position and the height you have in mind and the quotation follows those figures.
What is the minimum order quantity
One piece. There is no container minimum, which is why single projects in gardens and courtyards are a normal part of the workload here.
Why Corten weathering steel rather than something cheaper
Corten steel is alloyed so that the first layer of rust seals the plate underneath instead of eating into it, which is why the colour settles rather than keeps spreading. Architects want a warm, earth toned mass in a landscape without committing to a repainting cycle. Corten gives that without a coating system.
How is a water feature this size packed and shipped
A plywood crate is built around the finished geometry with foam on every finished face. Large water features are split into sections at joints chosen during design, trial assembled in the workshop, then marked so they go back together in the same order on site.
What do you need from me to quote
The position, the height or overall size you want, and any drawing, render or reference photograph you already have. For gardens and courtyards a photograph of the space is often enough to start.
What is the lead time
Lead time depends on the size of the water feature, the surface finish and how much design work it needs, so it is confirmed with the quotation rather than promised in advance. Send the brief and the schedule comes back with the price.
