Chrome, Satin Chrome and Satin Nickel 2026: Why Two Suppliers' "Polished Chrome" Do Not Match, and How to Specify One That Does

Put a satin chrome lever next to a satin nickel one under a showroom light and most people cannot name which is which. Put them side by side on the same door and everybody can see that they do not match.

That is the whole problem with this family of finishes: the differences are small, real, and impossible to describe in words accurately enough to reorder from.

Chrome is the thin bit on top

The first thing to understand, because almost everything else follows from it: a chrome-plated part is not mostly chrome.

A typical decorative chrome stack is copper, then nickel, then a very thin chromium layer on top. The copper levels the substrate and helps adhesion. **The nickel does the work** — it provides the corrosion barrier and most of the brightness. The chromium is a few tenths of a micron, and it exists to stop the nickel tarnishing and to add the slight blue cast that reads as "chrome".

Two consequences worth carrying away.

**A cheap chrome finish is cheap in the nickel**, not in the chrome. You cannot see that difference on delivery day; you see it two years later as dullness, then as pinholes, then as the substrate.

**Chrome and nickel are neighbours, not opposites.** Satin nickel is the same stack with the chromium step left off and the nickel finished satin. That is why the two look so similar and why the difference, once you know it, is easy to see.

The three finishes, separated by the property that matters

**The distinguishing property is the colour cast, not the sheen.** Chrome is cool and reads slightly blue; nickel is warm and reads slightly yellow. Once you have seen them together you cannot unsee it, and the cheapest way to see them together is two samples on one surface in daylight.

Sheen separates polished from satin within each family, and it is the easier axis: a mirror reflects an image, a satin surface reflects a blur.

The common mistake in a refurbishment is replacing satin chrome hardware with satin nickel or the reverse. Both are "silver, matte" in a written description. On a door beside an existing one they are visibly a different colour temperature.

Why two suppliers' "polished chrome" do not match

The code is the same; the result is not. Four reasons, all legitimate.

**The substrate.** Chrome over brass, over zinc alloy and over stainless do not look identical, because the base metal's colour influences the thin upper layers and because each takes polishing differently.

**The polish before plating.** Plating is faithful — it reproduces what is underneath, including grinding marks. A part polished to a higher standard before plating comes out brighter, and that labour is the largest cost difference between two chrome parts that look the same in a catalogue photograph.

**The nickel thickness.** As above. Invisible on arrival, decisive at year three.

**The satin texture.** "Satin" is not one texture. A directionally brushed surface, a bead-blasted one and a chemically etched one are all satin and all look different, especially in raking light. Two satin chromes can differ more from each other than a satin chrome differs from a satin nickel.

So a code establishes the family and the sheen. It does not establish the exact appearance. For anything where two suppliers' parts will sit on adjacent doors, the code has to be backed by a physical sample — which is why our samples page argues for a signed and retained reference rather than an approved photograph.

PVD is a different thing wearing the same name

Some hardware described as chrome or nickel is PVD — physical vapour deposition — rather than electroplate. It is a vacuum process depositing a very hard, very thin ceramic-like layer.

PVD is considerably harder and more wear resistant than electroplated chrome, which matters on a lever that thousands of hands touch daily. It also holds colour better in the finishes where it is used.

Two things to know before specifying it. The colour is not identical to the electroplated version of the same name, so PVD satin nickel and plated satin nickel on adjacent doors will not match. And it is a coating: where it is cut, drilled or worn through, the metal beneath is doing the work, which is the same argument our stainless page makes about finish not rescuing grade.

How to compare two samples so the answer means something

Most finish disputes come from comparing badly rather than from a real mismatch, and the fixes cost nothing.

**Compare in daylight, not under the showroom lamp.** Retail lighting is usually warm and it flatters brass while flattening the difference between chrome and nickel. North-facing daylight is the honest light, and it is the light the finished building will mostly be seen in.

**Put the two pieces touching, on one surface, at the same angle.** A satin finish is directional: the same part reads lighter or darker depending on which way the grain runs relative to the light. Two samples held at different angles will look like different finishes when they are identical.

**Compare the faces that will actually be seen.** A lever's grip and its rose are often finished differently — the grip gets handled and polished, the rose does not — so judging a set by its rose can mislead.

**Photograph the pair together if you need a record**, never separately. Two photographs taken minutes apart under the same light will still differ in white balance, and a comparison made from two images is not a comparison.

What destroys chrome and nickel, and it is usually the cleaner

This family of finishes fails far more often from maintenance than from wear, and the responsible products are on the shelf of every cleaning cupboard.

**Acidic and chlorine-based cleaners.** Limescale removers, bleach-based sprays and some washroom cleaners attack plated finishes, and washrooms are exactly where they get used daily. The damage appears as dulling and then as fine pitting, and it is not recoverable by polishing.

**Abrasives.** Cream cleaners and scouring pads cut through the chromium layer, which is a few tenths of a micron thick. Once it is through, the nickel below tarnishes and the finish is visibly two colours.

**Standing water at the fixings.** Water that sits where a rose meets the door works under the plating edge, and the failure starts at the screw and spreads.

The correct regime is dull and worth writing into the handover documents: warm water, a mild neutral detergent, a soft cloth, dried afterwards. Our corrosion page makes the same argument for stainless — that maintenance is part of a material specification rather than an afterthought to it — and it is more true here, because a plated finish has no self-repairing layer to fall back on.

Where a building will not do that — a public washroom, a school corridor — say so at specification stage. A harder finish such as PVD, or a material whose surface is its own colour like solid stainless, costs more once and removes the failure mode.

What our own finish rows look like, counted

There is a data problem in our catalogue that this page is the right place to admit, because it is exactly the failure the page warns about.

Across 336 published finish rows, the same finish is written several different ways. "Satin Nickel (SN)" appears 41 times and "Satin nickel" 38 more. "Polished Brass (PB)" appears 68 times, "polished brass" 19 times and "Polished brass (US3)" 16 times. Chrome appears as "Chrome Plated (CP)" 51 times, "Satin Chrome (SC)" 18 times and bare "chrome" 17 times.

Those are not different finishes. They are one finish written inconsistently, and the rows without a code are the ones a buyer cannot reorder from — which is the argument this whole page is making, turned on ourselves.

It is being normalised against the code table on our finish code page rather than left to tidy itself. Until it is, take the code where a row has one and ask where it does not.

How to specify chrome so you get the same thing twice

Give the code, not the name. US26D or 626, not "satin chrome".

Name the substrate if the project mixes materials — chrome on brass and chrome on zinc alloy will not match on adjacent doors.

Say whether PVD is acceptable, because a PVD equivalent is a legitimate substitution that changes the colour slightly.

For anything visible together, approve a physical sample and keep it. A code plus a signed sample is a specification. A code alone is a family.

And specify every item on the opening to the same code, including the hinges, the strike and the screws. The mismatch everybody notices is not two levers; it is a satin chrome lever above a polished chrome strike. That is one line in a specification and it settles an argument that would otherwise arrive four years later, with nobody left who remembers what was approved.
