Surface Finish Polished

A polished finish is metal at its most honest. Through progressive stages of sanding and buffing, the raw surface is refined until it becomes a mirror, bright, reflective, and unmistakably metallic. There is nothing applied and nothing hidden. What you see is the material itself, brought to its best.

What a Polished Finish Looks Like

Bright and reflective, with a liquid quality that shifts as you move around it. A polished aluminium frame catches and bends light across its surface, giving the profile a sleek, almost liquid appearance. Polished brass has a warmer, deeper glow, rich and golden without being ornate. Polished steel sits somewhere between the two: cool, hard-edged, and industrial.

The effect is inherently contemporary. A polished frame makes a quiet but confident statement, it reads as precise, considered, and architecturally aware. It draws the eye without competing with the artwork inside it, which is exactly what a good frame should do.

How Polishing Is Done

Achieving a mirror polish on metal is a multi-stage process that cannot be rushed. Each stage removes the scratches left by the previous one, using progressively finer abrasives until the surface is smooth enough to reflect light cleanly.

Coarse sanding. The process begins with a relatively coarse abrasive to remove weld marks, tool marks, and surface irregularities. On a welded frame, particular attention is paid to the corner joints, these must be perfectly flush before any polishing begins.

Progressive grits. The frame is worked through a sequence of increasingly fine sanding grits. Each pass removes the scratch pattern of the previous grit and replaces it with a finer one. This may involve four to six grit changes, depending on the metal type and the starting condition of the surface.

Buffing. Once the sanding stages are complete, the frame is buffed with polishing compounds on a soft wheel. This is where the mirror finish emerges, the compound fills and smooths any remaining micro-scratches, and the soft wheel brings the surface to a bright, reflective shine.

Sealing. The polished surface is sealed with a clear protective coating. This is essential, without it, the metal would oxidise and fingerprints would mark the surface within hours. The sealant preserves the reflective finish and makes the frame practical to handle and display.

Where a Polished Finish Works Best

Polished frames have a natural affinity with contemporary and minimalist settings. Their clean reflective surfaces pair well with modern photography, abstract art, architectural prints, and graphic work. In a white-walled gallery space, a polished aluminium frame virtually disappears, just a thin line of light around the artwork.

They are also a strong choice for:

• Commercial and corporate interiors, the bright finish reads as professional and precise

• Mirrors, a polished metal frame complements the reflective surface of the mirror itself

• Architectural spaces, lobbies, stairwells, and feature walls where the frame contributes to the material palette of the room

• Welded frames, polishing is a natural partner for welded construction, emphasising the seamless metallic form

Compatible Materials

Polishing is a metal-only finish. The metals we polish most often are:

• Aluminium, lightweight, polishes to a bright silver tone. The most popular choice for polished frames, especially at larger sizes where weight matters.

• Brass, polishes to a warm golden finish. Brass has more visual warmth than aluminium and suits spaces where you want the metallic tone to be a deliberate design element.

• Stainless steel, the hardest to polish but produces the most durable result. Steel has a cooler, harder character than aluminium and exceptional resistance to corrosion.

Durability and Care

A sealed polished finish is surprisingly low-maintenance. The clear protective coating prevents oxidation and makes the surface resistant to fingerprints. For day-to-day care, wipe with a soft dry microfibre cloth. If the frame needs a deeper clean, a damp cloth followed by a dry one is sufficient, avoid abrasive cloths or chemical cleaners, which can scratch or dull the sealant.

Over many years, the sealant may gradually wear in areas of frequent handling. If the polish starts to dull, the frame can be re-polished and re-sealed, the underlying metal is unchanged, so the finish can be restored to its original brightness. This is another advantage of polishing: unlike applied coatings, the finish is inherent to the material.

Cost and Commissioning

Polishing is labour-intensive. The multi-stage sanding and buffing process takes considerable time, especially on larger frames or complex profiles. The main cost factors are frame size, the number of faces to be polished (a box profile has more surface area than a flat profile), and the type of metal, harder metals like stainless steel take longer to bring to a mirror finish than aluminium.

Polished frames are most commonly produced as welded metal frames, where the combination of welded construction and a polished finish creates a seamless, monolithic appearance. The frame looks as though it has been machined from a single piece of metal.
