Faucet Finishes Explained: Chrome Plating, PVD and Powder Coating
The finish is the first thing a customer sees on a faucet and the first thing they complain about when it goes wrong. Pitting, peeling, colour that does not match the shower head next to it, a black finish that turns grey after a year of cleaning – almost all finish failures can be traced back to which process was used and how it was specified in the order.
This guide explains the three finishing processes you will meet when buying faucets and showers – electroplating, PVD and powder coating – what each is good at, and how to specify and check them so that the finish you approve on the sample is the finish you receive in the container.
The three processes at a glance
| Electroplated chrome | PVD colours | Powder coating / paint | |
|---|---|---|---|
| How it is applied | Layers of nickel and chromium deposited from chemical baths using electric current | A thin metal-nitride or similar layer deposited in a vacuum chamber, usually on top of an electroplated base | A polymer layer sprayed on and cured with heat |
| Typical colours | Bright chrome; brushed (satin) nickel looks | Gold, brushed gold, rose gold, gunmetal, black, brushed nickel | Matte black, matte white and almost any solid colour |
| Scratch and wear resistance | Good | Very good – the PVD layer is very hard | Lower – the coating is softer and can chip at edges |
| Colour consistency | Easy to keep consistent | Needs colour control between batches | Good within one batch of powder |
| Cost level | Lowest | Higher | Low to medium |
Electroplating: the base of most faucet finishes
A standard chrome faucet is not “chrome-coloured brass”. After casting, machining, grinding and polishing, the body is cleaned and electroplated with a layer of nickel and then a very thin top layer of chromium. The nickel does most of the work: it levels the surface, gives the bright look and provides most of the corrosion protection. The chromium on top adds hardness and the blue-white chrome colour.
Most electroplating defects start before the part reaches the plating line. Porosity in the casting, grinding marks that were not polished out, or poor cleaning lead to pits, bubbles and peeling that appear weeks or months later. That is why plating quality and casting quality cannot really be judged separately.
For tapware sold in Europe, EN 248 sets requirements for electrodeposited nickel-chromium coatings on sanitary tapware, including adhesion and corrosion testing. Ask your supplier which standard their plating is tested against, even if you sell outside Europe – it gives both sides a common reference.
PVD: hard colours on top of plating
PVD (physical vapour deposition) is the process behind most metallic colours on modern faucets: brushed gold, rose gold, gunmetal and many blacks. The parts are loaded into a vacuum chamber, where a metal such as zirconium or titanium is vaporised and reacts with gases to form a very thin, very hard coloured layer on the surface.
Two points matter for buyers:
- PVD sits on a base. On brass faucets, PVD is normally applied over an electroplated nickel-chrome layer. The PVD layer gives the colour and the scratch resistance; the plating underneath still provides the corrosion protection. A weak base under a PVD colour will fail just like an ordinary chrome finish.
- Colour depends on process control. The shade of a PVD colour depends on the gas mix, temperature, time and the position of the parts in the chamber. Two batches can come out slightly different, which is very visible when a basin faucet and a shower set from different batches are installed side by side.
“Gold-colour” does not always mean PVD. Some lower-cost gold or black finishes are lacquered or painted over plating. When a finish name is used in a catalogue, ask which process is behind it.
Powder coating and paint: matte colours
Matte black and matte white faucets are often powder coated or painted rather than PVD coated. Powder coating can give a deep, even matte colour at a competitive price, and almost any colour is possible. The trade-off is durability: the coating is softer than PVD, can chip at sharp edges and around the handle, and can lose its matte look if it is cleaned with abrasive products.
Powder coating is a reasonable choice for products that are handled less – such as shower heads, shower arms and bath spouts – or for price-driven ranges. For basin faucets and kitchen faucets that are touched and cleaned every day, a PVD black is the more durable option if the budget allows.
Brushed finishes
“Brushed” describes the texture, not the coating. The surface is brushed to a fine linear grain before plating or PVD, so brushed gold is typically a brushed surface with a PVD gold layer. Brushed finishes hide fingerprints and water marks better than polished finishes, but the grain direction and fineness should be agreed on the sample, because they change the look noticeably.
How to specify a finish in your order
A finish name such as “brushed gold” is not a specification. To avoid disputes, agree the following in writing for each finish:
- Process: electroplated, PVD over plating, or powder coating/paint.
- Base material: brass, stainless steel or zinc alloy. Zinc alloy parts are harder to plate well; ask which parts, such as handles, are not brass.
- Colour standard: a signed colour sample kept by both sides. For coloured finishes, agree how colour will be checked – for example visually under a defined light source, or with a colour measurement tolerance.
- Corrosion test: the test method (neutral salt spray or CASS) and the number of hours, and the pass criteria.
- Adhesion test: how coating adhesion is checked on production samples.
- Matching parts: whether handles, escutcheons, hoses, shower heads and drains in the same order will come from the same finish batch.
Ask the supplier for a short report of the corrosion and adhesion tests they run on your production batch, not only on the original sample. A finish that passes once in the lab and is never checked again is the most common reason for finish complaints in later orders.
Checking finishes on samples and production
- Inspect in daylight or a light box from several angles. Look for pits, orange-peel texture, haze, polishing marks and colour differences between the body and the handle.
- Compare every coloured part against the approved colour sample, especially when an order mixes basin, kitchen and shower products in one finish.
- Check hidden areas: under the spout, around the base and inside the handle. Thin plating usually shows first in recesses.
- Check that all parts that are visible after installation – including the cover plate, drain and hose ends – are finished, not only the main body.
Care instructions reduce complaints
Many finish complaints are caused by cleaning, not by the factory. Strong limescale removers, bleach and abrasive pads attack chrome, PVD and powder coatings alike. Including a short care card in the box – clean with mild soap and water, dry with a soft cloth, no abrasive or acidic cleaners – is a cheap way to protect your brand. Ask for it to be printed in the languages of your market.
Which finish should you offer?
Chrome remains the best-selling and most forgiving finish and should anchor most ranges. Add PVD colours where your customers expect a premium look, and make sure your supplier can match the colour across every product in the set. Use powder-coated matte colours where price matters more than long-term wear, and be clear with your customers about the difference.
DACHENG offers several of its basin, kitchen and shower series in more than one finish. You can compare the Deva Series, with models shown in chrome, brushed, brushed gold, gunmetal and black, and the Rose Gold Collection, then confirm the finish process and test requirements for your order when you request a quotation.
