🟤 Corten Steel: Bold & Outdoor-Ready

Corten steel signs are designed to weather beautifully, developing a stable, protective rust layer — the quintessential industrial look.

🌦️ Interior vs Exterior: What to Choose?

• Interiors: Lacquered brass, copper or zinc deliver refined, low-glare finishes. Aged/antique patinas add warmth.
• Exteriors: Corten is ideal outdoors. Brass and copper also work well if sealed; select appropriate fixings and standoff mounts.
• Lowest maintenance: Zinc (pre-weathered) and Corten (naturally stabilising) need the least upkeep.

✍️ Engraving, Lettering & Build Options

• Engraving: Rotary engraving with black enamel infill on satin brass offers superb legibility; laser or CNC engraving also available.
• Letters: Individual brass/copper letters, shapes and logos cut to size for reception walls and façades.
• Fabrication: Folded trays, standoff panels, fret-cut faces with backers, and illumination provisions on request.

FAQs: Choosing Metal for Signs

What’s the best metal for outdoor signs?

Corten steel is purpose-made for exterior weathering. Brass and copper also perform well outdoors when correctly sealed and mounted; zinc is ideal where a subtle, low-maintenance look is required.

Which finishes give the best readability?

Satin/brushed brass with engraving + black infill maximises contrast and reduces glare. Mirror finishes are striking but can reflect surroundings; great for logos and prestige interiors.

Will my sign change colour over time?

Yes, if you select a living finish. Brass and copper gently deepen; zinc mutes; Corten stabilises to a chestnut rust. Choose lacquered/sealed finishes for a more fixed appearance.

How do I maintain metal signs?

Usually a soft cloth with mild soapy water. Avoid abrasives. Exterior brass/copper benefit from periodic checks of lacquer/seal. Corten is essentially maintenance-light.
