Custom Corten Signs, Name Boards & Letters Cut to Your Artwork
Dinesh Tube India supplies Corten steel signage from Mumbai to architects, landscape designers, builders, hotels, corporate campuses and sign companies. We supply name boards, cut letters, logos, entrance and monument signs, house name plates and wayfinding signs in genuine weathering steel, cut to your artwork, as well as Corten sheet blanks for sign makers who do their own cutting.
Signs are made from the same Corten steel sheets and plates we supply for industrial work: ASTM A242 (Corten A), ASTM A588 (Corten B) and EN S355J0WP. That means a real weathering steel patina, not a painted rust effect.
Why Corten for Signage?
Corten (weathering) steel forms a stable orange-brown rust layer outdoors that protects the steel underneath, so an outdoor sign needs no paint and little maintenance. The colour deepens from orange to dark brown over months and years, which suits landscaped entrances, heritage settings, resorts and modern architecture.
Corten only weathers properly where it gets regular wetting and drying in the open air. Indoors it barely changes colour unless it is pre-rusted, and in coastal splash zones or places that stay wet the patina may not stabilise. Corten is not stainless steel, and run-off from new Corten can stain the surface below, so the design should allow for it (see design and mounting).

Corten Signage Thickness Guide
Guidance only. Thin sheet loses a larger share of its section to weathering over time, so use thicker material for signs meant to last decades outdoors.

Corten Steel Signage: FAQs
How long does a Corten steel sign take to rust?
Outdoors, a natural-finish Corten sign usually turns orange within a few weeks of rain and dew, then darkens to a deep brown over several months to a few years, depending on climate. If you want the rusted look on day one, ask for a pre-rusted finish.
Will a Corten sign rust through?
Not in normal outdoor use. The patina on genuine weathering steel slows further corrosion, so a properly detailed sign lasts many years. Thin sheet, places where water collects, sites close to the sea and permanently damp spots shorten its life, so choose a suitable thickness and let the sign dry out between rains.
Does Corten steel stain walls and paving?
Yes, at first. Rainwater running off a new Corten sign carries rust and can stain light stone, plaster and paving for roughly the first year. Plan a gap, a drip edge or a gravel strip below the sign, or use a sealed finish where staining is not acceptable.
Can Corten signs be used indoors?
Yes, but Corten will not develop its patina indoors because it does not go through wet and dry cycles. For reception walls and interiors, order a pre-rusted and sealed finish so the colour is fixed and rust does not rub off.
What thickness should a Corten sign be?
As a guide: 1.5–2 mm for house plates and small plaques, 3–5 mm for wall letters and logos, 3–6 mm for name boards and panels, and 5–10 mm for freestanding monument and pylon signs. Large or exposed signs need a frame and base designed for wind load.
Is Corten signage better than a painted rust-effect finish?
Genuine Corten forms its colour from the steel itself, so it does not peel or need repainting, and the colour keeps developing naturally. Rust-effect paint on mild steel looks similar at first but can chip, and the mild steel underneath corrodes without protection once the coating is damaged.
What file do you need to cut a Corten sign?
A vector file such as DXF, DWG, AI or a vector PDF is best, with the overall size marked. If you only have a logo image or a sketch, send it with the size and wording and we will advise on the next step.
Do you supply Corten sheet to sign makers?
Yes. Sign and fabrication companies can buy Corten sheet and cut blanks in ASTM A242, ASTM A588 and S355J0WP for their own cutting. See our Corten steel plates and sheets page for grades and sizes.
