In the world of outdoor sculpture and public art, one material continues to capture the imagination of designers, developers, and artists alike—CorTen steel. 🌿🛠️

Also known as weathering steel, CorTen develops a striking rust-like appearance over time while maintaining its structural strength. But what makes it so desirable for outdoor installations? And how do you ensure your sculptural CorTen work stands the test of time?

At South Coast Metal Fabrication (SCMF), we regularly work with CorTen to create timeless, durable and visually bold public artworks across Brighton, Sussex, and beyond. Here’s everything you need to know about this unique material. 👇

🔍 What Is CorTen Steel?

CorTen (short for “CORrosion resistance” and “TENsile strength”) is a specially formulated steel that intentionally rusts to form a stable, protective surface.

Unlike ordinary steel, this oxidised outer layer acts as a barrier, preventing deeper corrosion and eliminating the need for paint or coatings. 🌧️🧱

That means:

Incredible longevity
Low maintenance requirements
A warm, earthy appearance that blends beautifully into natural or architectural settings

Ideal for sculpture, signage, and garden features alike.

🎨 Patina: Beauty That Evolves

One of CorTen’s most celebrated features is its evolving patina. From silvery grey to deep ochre orange, the tones shift naturally over time based on environmental conditions. 🍂

Key patina facts:

It takes 6 to 12 months for the patina to fully stabilise
Rain, sun, and wind accelerate the weathering process ☀️💨🌧️
Colour will vary slightly by location, adding uniqueness to each piece

This living finish makes CorTen ideal for art collectors, architects, and landscape designers seeking a sculpture that interacts with its environment.

🏗️ Structural Strength & Engineering

Beyond its rustic charm, CorTen is a seriously strong material. That’s why it’s used in:

Bridge construction 🌉
Architecture & facades 🏢
Large-scale public artworks 🗿

For sculpture, CorTen offers both stability and longevity—making it perfect for:

Windy coastal locations 🌬️
Urban plazas and parks 🏞️
Schools, civic centres, and new developments 🏫

At SCMF, we ensure each structure is properly supported with suitable thickness, footings, and fixings. Our background in architectural and artistic fabrication means your piece isn’t just beautiful—it’s built to last. 💪

🧽 Care & Maintenance Tips

While CorTen is famously low maintenance, a little knowledge helps preserve its integrity and aesthetics:

Avoid constant water pooling at the base to prevent over-oxidation 🚫💧
Use drainage channels or raised footings for larger sculptures
The rust can stain paving during its first weathering cycle—allow for runoff or seal nearby surfaces 🧱🟠
No painting or varnishing required—just let nature do the work! 🌿

For pieces near buildings or footpaths, we’ll help plan drainage and protection as part of the design.

🧠 Smart Design for Public Art

When commissioning public art in CorTen, it’s not just about materials—it’s about concept, placement, and durability.

Our team supports clients through:

Design and 3D modelling 🖥️
Planning permissions and site consultations 📋
Engineering for wind load, footfall, and safety ⚙️
Installation and long-term aftercare 🏗️

We’re experienced in collaborating with councils, architects, and arts organisations to bring ambitious CorTen sculptures to life—on time and on budget.
