An aged or antique metal finish is created by encouraging controlled oxidation on the surface of a metal sheet or panel. Through a combination of chemical patination, heat and finishing techniques, the surface colour and texture of the metal can be altered to produce the appearance of natural ageing.

Unlike painted or coated surfaces, patinated metal finishes remain authentic metal surfaces, meaning the colour is created through changes in the metal itself rather than through an applied coating.

Key characteristics of aged metal finishes include:

• subtle colour variation across the sheet

• tonal depth created by natural oxidation

• a surface that reflects light differently depending on angle and texture

• the ability to seal the finish to stabilise the appearance

Depending on the metal used, finishes may range from warm antique brass tones to deep copper browns or dark zinc patinas.

Brass develops some of the most visually distinctive aged finishes of any architectural metal. Through controlled patination and finishing techniques, brass sheets can range from warm antique golden tones through to darker burnished surfaces that emphasise the natural grain and character of the metal.

These finishes are widely specified for interior architecture, signage and decorative metalwork where designers want the appearance of naturally aged brass combined with the consistency of a controlled workshop finish.

Typical aged brass finishes include:

Antique Brass

Antique brass finishes create a warm, slightly darkened golden tone with subtle tonal variation across the sheet. This finish replicates the look of naturally aged brass while maintaining a refined and balanced surface appearance.

Common applications include:

• decorative wall panels
• bar fronts and counters
• architectural detailing
• signage panels and plaques

Aged Brass

Aged brass finishes introduce deeper oxidation and increased tonal variation across the surface. The patination process produces a finish that appears naturally weathered while retaining the underlying warmth and colour of the brass.

This finish is often specified for:

• hospitality interiors
• reception desks
• feature panels
• bespoke furniture surfaces

Burnished Brass

Burnished brass combines patination with mechanical finishing techniques to highlight the texture and movement of the metal surface. The result is a richer, slightly darker brass finish with visible grain patterns and enhanced depth.

Typical uses include:

• statement wall cladding
• decorative panels
• design-led interiors

Zinc is widely used in architecture and interior design because of its soft, natural patina. When aged or chemically treated, zinc can develop a range of grey and dark patinated surfaces.

Dark Patina Zinc

Dark patina zinc finishes create a deeper grey surface with subtle tonal variation. The finish retains the characteristic softness of zinc while adding visual depth.

Applications include:

• wall cladding

• interior panels

• signage backgrounds

• architectural detailing

Multi-Tonal Zinc

Multi-tonal zinc finishes combine different patina shades across the sheet surface, producing a distinctive finish with natural variation. This finish is particularly effective in large panels where the tonal movement becomes a design feature.

Zinc patina finishes are often specified for contemporary interiors and architectural projects.

More information about zinc surface treatments can be found on our Zinc Finishes page.

Aged and patinated metal sheets are used across a wide range of design and fabrication projects.

Architectural Interiors

Designers frequently specify aged metal panels for interior cladding and feature surfaces. The variation and depth created by patination help add warmth and texture to modern interiors.

Typical uses include:

• wall cladding

• reception counters

• bar fronts

• lift surrounds

• decorative panels

Signage & Branding

Patinated metals are widely used for signage and branding elements. The aged finish creates a distinctive appearance while maintaining the durability of solid metal.

Examples include:

• engraved plaques

• laser cut signage panels

• logo plates

• architectural wayfinding

Furniture & Decorative Metalwork

Aged and patinated metals are also used for bespoke furniture and decorative metalwork, particularly where designers want a finish that will develop character over time.

Common applications include:

• table tops

• cabinet fronts

• decorative furniture panels

• architectural details

While metals such as brass, copper and zinc will naturally develop patina over time, controlled patination allows designers to achieve the desired appearance immediately.

Natural ageing occurs slowly as the metal reacts with air and moisture. This process can take months or years depending on environmental conditions.

Controlled patina finishes replicate this process in a workshop environment using specialist techniques. This allows:

• consistent colour across panels

• predictable finish tones

• faster installation for design projects

In many cases the patina can also be sealed to stabilise the finish and reduce further surface change.

When specifying aged metal finishes, designers should consider several factors:

Lighting
Patinated surfaces respond strongly to lighting. Directional lighting can emphasise tonal variation and surface texture.

Finish variation
Because aged finishes are created through oxidation, subtle variation between sheets is normal and often desirable.

Sealing options
Some projects benefit from sealing the finish to stabilise colour and simplify maintenance.

Material selection
Different metals produce different patina characteristics. Brass tends to create warmer tones, while copper and zinc often produce deeper and cooler finishes.

Some finishes also combine patination with mechanical surface treatments. For examples of these surfaces see our guide to Burnished Metal Finishes.
