Industrial Finishes

Industrial finishes focus mainly on lengthening the life of the product. They can achieve this by preventing corrosion, hardening the surface to wear better, improving the lubricity, adding a sacrificial plate to maintain the base structure, and by removing any trace metals form the surface to prevent corrosion from starting. Below are many of the items we do to help your part last a longer more productive life. Before you send your product into the field it is highly advisable to consult with our team to make sure the protective coating you are applying will stand up to the harsh environment they often work in.

Iron Phosphate
This process is a simple dip process to enhance the grain structure prior to painting or powder coating. The process can also be used to prolong the shelf life of steel parts before they are used in the field. It is simple and inexpensive but offer very little corrosion protection by itself.

Black oxide
would be similar in process but offer more corrosion protection while on the shelf. It also has limited corrosion protection but does make the appearance of machine parts stay without rusting in warehouse conditions. The down side is additional coatings , such as powder or E coat , can not be added over the top of black oxide. An oily dip can be added to give extra protection in humid or salty warehouse conditions.

Zinc plating
would be the next step up and offers a very nice metallic finish. This product is usually covered with a chromate conversion coating that can be done in yellow, drab, clear or black. The corrosion protection is enhanced because the zinc is a sacrificial metal and corrodes before the base metal. The appearance of a zinc plated product is superior to hot dipped and often used for that reason.

Tin plating
helps in corrosion and tarnishing as well as adding lubricity. In the electronic fields the tin plate can be easily soldered to. Tin is also used in the food industry to prevent rusting on steel parts that touch the food.

There is also electro galvanize coatings that add even more protection. It too is a sacrificial coating but is deposited thicker and lasts longer than the zinc plated product. This service would be used where an added protection is wanted and the main concern is the base metal integrity.

Electroless nickel
deposits are very noble and protect the base metal by covering the surface with a pit free coating. There are three levels of corrosion protection from three distinct baths. Thickness of deposit also plays an important role in the corrosion protection.

All of the coating in industrial plating are designed to make your part last longer.
