Buy Corten steel sheet metal from Metal Sheets Ltd — UK suppliers of high-quality Natural and Rusted (Weathered) Corten Steel for architecture, landscaping, signage, public art, cladding, and interior features.

We supply Corten steel sheet in its natural bright finish or with a controlled rusted patina produced in our workshop. In addition to flat sheets, we also manufacture rusted Corten signs, wall art, cladding panels, public art installations, and bespoke kitchen and architectural features.

Corten steel sheets are supplied in the natural state, where surface oxidation may begin during storage or transport. This is normal and does not affect performance. When exposed to outdoor conditions, the material will age naturally, developing its characteristic protective patina over time.

Pre-rusted Corten sheets are available where an immediate weathered appearance is required. For interior use, rusted surfaces can be sealed with a clear matte lacquer or wax to reduce rust transfer.

Samples are available free to architects, designers, and educators — please email sales@metalsheets.co.uk to request one.

Corten Steel Corrugated Sheet

Corten corrugated sheet is similar in profile to galvanised corrugated steel but manufactured in weathering steel. Sheets are typically supplied in a natural bright finish and will develop a uniform rusted appearance when exposed to outdoor conditions. Pre-weathered corrugated sheets can also be supplied for projects requiring an immediate aged aesthetic.

Trade Supply & Fabrication Support

If you’re specifying Corten steel for a project, we offer trade supply of full and part sheets, along with manufacturing support for fabricated components, rusted finishes, and architectural detailing.

Supporting Services for Corten Steel Projects

We support Corten steel projects from raw material supply through to finished, rusted components. For shaped parts, signage, or fabricated elements, we can quote from your drawings and advise on the most suitable production route.

• Straight-edge trimming on stocked Corten steel sheets
• Laser profiling from DXF/PDF files (quoted to project)
• Fabrication & welding from drawings or sketches
• Controlled rusting — accelerated weathering of full sheets and fabricated components
• Corten signage — laser-cut lettering, plaques, and public art features
• Surface sealing — clear lacquer or wax for interior applications

What Is Corten Steel?

Corten steel (also known as weathering steel) develops a stable protective rust patina through repeated wet and dry cycles. This patina forms a barrier that significantly slows further corrosion, unlike standard mild steel which can continue to rust until failure.

The alloy contains controlled amounts of copper, chromium, nickel, and phosphorus, giving it enhanced atmospheric corrosion resistance and its distinctive appearance. Environments without natural wet/dry cycles may not form an effective patina, which is why controlled rusting is often specified for architectural and interior projects.

If you’re looking to buy Corten steel sheet metal — whether natural, pre-rusted, flat, or corrugated — Metal Sheets Ltd offers the stock, finishing options, and fabrication expertise to support your project.
