The Complete Guide To Metal Finishes: Everything You Need To Know

Before a metal is finally used, it must undergo various forms of treatments or modifications. One of these treatments entails doing metal finishing. Metal finishing is a common practice that is utilized to treat the outside of a metal surface by applying a slight correlative layer to its surface.

There are various kinds of metal finishing forms that you can use for an assortment of purposes. In this article, we will survey the significant metal finishing techniques, its applications and the tips for picking the best metal finishes.

What is Metal Finishing?

Metal finishing is a process by which the external surface of a metal product is treated by means of applying a thin layer. This layer sticks to the surface of the metal so that the two become homogeneous.

Just as the name suggests, finishes are among the final treatments that are done on metals. They change the appearances and texture of the metal surfaces. For instance, a dull metal will suddenly transform into a shiny piece of art after it has undergone a finishing.

Some metal finishes are even capable of changing the structural properties of the metal. In doing so, they tend to increase the strength and durability of metal. Your metal will become resistant to corrosion and rust.

Since metal finishes come in different forms, you should expect different results from each finishing. Also, some finishes are suitable for a particular class of metals and not suitable for others.

Why Metal Finishing- Benefits of Metal Finishes

Is metal finishing worth the cost? Yes, you should invest in metal finishing as it comes with numerous advantages. Here are the top benefits of doing metal finishing:

1. Improved appearance

Let’s face it, raw metal is not one of the things that you will consider looking at twice. In other words, it is ugly. Metal finishing is designed to solve this problem by improving the physical appearance of a metal.

Different metal finishes will change the outlook of the metal surface. If you are planning to use the metal as a decorative feature, then you will put more emphasis on the finishing. This will ensure that you achieve your goal easily.

Through metal finishing, you will be able to get rid of sharp edges, stains, rough surfaces among others. You will smoothen the metal surface and apply other different decorative features. It is also easy to modify the decorative options for the metal finishes.

2. Resistance to scratches and corrosion

Metal finishes

The top layer of the metal finishes provides protection against scratches or corrosion. These two forces occur when the metal gets into contact with other materials. Continuous corrosion tends to degrade the overall quality of the metal. The finishing will act as a cover.

Also, the finishes tend to produce low co-efficient of friction which enhances the resistance to abrasion. This minimizes the effect of wear and tear on the metal resulting in durable metal.

3. Easy and convenient to clean

Over time, your metal will accumulate dust and dirt. This will leave you with no other option but to clean it. Now, think about cleaning a raw metal surface. The task can be too difficult and even destructive.

A metal finishing provides the easiest way of cleaning your metal. The smooth layer of the finishing will ensure that you do the cleaning within a short time. Also, you will not have to worry about the dangers of using the cleaning agent on the metal s the finishing will protect the metal.

4. Chemical protection

The extra layer on the metal surface provides protection against the effects of chemicals. Corrosive chemicals that can damage the metal will be kept at bay. The finishing can also prevent problems such as rust on metals.

5. Reduces electrical resistance

If you are using the metal to transmit electricity, the finishing can reduce its resistance to electricity. It achieves this goal by ensuring that the electrons are not interfered with by external factors such as temperature.

Minimum electrical resistance transmits to the reduced cost of electrical transmission.

As you can see, the benefits of metal finishes are so immense that you cannot ignore them. They affect almost every other aspect of the metal. So, you should consider investing in quality metal finishes.

Types of Metal Finishes

Types of metal finishes source

As we have already mentioned, there are different types of metal finishes. Each type has its unique features, advantages, and disadvantages. These types include but not limited to:

1. Metal Plating

Metal plating entails applying a coat over the surface of the metal. It can also entail altering the external structure of the metal so that it can be safe. There are two main types of metal plating for metal finishes. These are;


-Electroless plating

Electroplating which is also known as electrodeposition entails passing the electric current through a solution of an electrolyte. The two electrodes are dipped in the solution then are connected to a power source. These electrodes are metals that should be electroplated. The atoms of the electrolyte will form on the electrodes.

The electrolyte chosen will depend on your target goal. For instance, gold electrolyte can be chosen for its aesthetic value while zinc will be chosen for its protective role.

On the other hand, electroless metal plating does not involve the use of electric current to coat the metal. Instead, the metal is immersed in a solution full of copper, nickel or any other targeted coating medium.

Electroless metal plating is an ideal method for enhancing corrosion resistance of a metal. It is also used on entails that will be used for sensitive applications such as food and gas industry.

2. Brushed metal finishing

Brushed metal finishing is usually done with the purpose of removing all the imperfections that may be lying on the surface of the metal. The finishing is aimed at creating a smooth and uniform texture on the metal surface.

A wire brush or an abrasive belt can be used for doing this job. The brushing is unidirectional hence can create a desired aesthetic appeal. The method is commonly used in the automotive industry and for electric appliances.

3. Buff Polishing

Buff polishing is considered as the best alternative for the electroplating method of metal finishing. It can achieve the same result as electroplating without the use of electrochemical. Instead, a buff machine with a cloth wheel is rolled over the metal surface. The result is a clean, smooth and glossy finishing.

You should consider using it if you want to achieve a smooth finishing. This explains why it is mainly considered for metals that will be used for decorative applications. However, it is not ideal for the fragile and complicated applications due to the limited nature of the cloth wheel.

4. Metal Grinding

Metal grinding entails scrubbing out the surface of the metal so as to get rid of any imperfections or metal ions. The grinding machine utilizes the forces of friction and abrasion to smoothen the metal surface.

There are many grinding tool options that can be used for such applications. They include bench grinders, wheel grinders, custom grinding machines, among others. The choice of a grinding tool will depend on the type of metal and area of application.

Metal grinding is a preferred choice of metal finishes that require shallow cuts.

5. Sand Blasting

You can use the sandblasting technique of metal finishing when you want to attain a uniform matte texture on your metal. Also known as bead blasting, the method forces metal pellets, sand, steel shots, and other abrasives into a single substrate.

An abrasive medium that is flowing at a high speed is forced against the metal to remove all forms of debris. The speed and pressure of the medium can be controlled depending on the goal that you would like to achieve. This method can also be used to prepare the metal for other types of finishes such as coating.

6. Powder coating

Although it is usually viewed as a decorative method finishing method, there is more than you can achieve with powder coating. It increases the durability of metal. Powder coating entails melting dry plastic powder onto the surface of the metal. The result is a matte, smooth texture and glossy coating. Powder coating can also eliminate the surface blemishes on a metal.

7. Hot blackening

This type of metal surface finishing entails spreading a thin layer of black oxide onto the surface of the metal. The end result is a matte black finish that has a high resistance to corrosion and abrasion.

The process is characterized by high temperature so coolant is used after the finishing. Hot blackening is mainly used during the production of automotive parts.

Factors to Consider When Choosing Metal Finishes

Of the above-listed types of metal finishes, which one should I choose? Given that each type of metal finishing has its unique property, you should always strive to choose the best one. Here are some of the factors that you should carefully consider when choosing the metal

1. Color of the metal finishes

Different types of metal finishes have different colors. If the metal will be used for decorative purposes, then you will have to pay attention to the color effect that it will create. The color of the metal finishing will have a direct impact on the interior and exterior design, whether it is in a building or on a vehicle.

The good news is there are plenty of options to play with when it comes to choosing the colors of the metal finishes. You should select the finishes that match your desired color.

2. The application area/Environmental condition

Here are you planning to use the metal? The internal conditions and environment will play a critical role in determining the finishes type that you choose.

If the area experiences high humidity, then the metal finishes should provide adequate protection against corrosion. If the metal will be installed in an area that experiences plenty of movements, the finishing should protect against the effects of friction and abrasion.

3. The cost of metal finishes 

How much are you willing to spend on the metal finishes?b The price tends to vary from one type of metal finishing to another. Some are cheaper than others.

However, you should not just focus on the price alone. Compare it with the quality and the impact that it will create. This is because although some metal finishes may be cheap, their quality may not be very good. But still, you should strive to get affordable metal finishes.
