Surface Treatment

Metal surface treatment allows giving your product the desired look. But even more importantly, it lengthens the lifetime of metal. Smoothing the surface area and coating it afterwards protects metal from the surrounding environment.

Surface treatment pricing depends on the surface area, volume and amount of metal detailing. For a specific surface treatment pricepoint, add a PDF or an STP file to your request on Fractory’s automatic platform and we’ll get in touch in 24h.

Surface Treatment

Fractory’s network of manufacturing partners provide surface finishes according to your specific needs. It’s possible to treat a wide range of metals – from small items to heavy constructions. We provide the service for a variety of metals, both ferrous and non-ferrous.

We offer the following metal surface treatment methods:


While laser cutting usually leaves nice clean edges (except for aluminium laser cutting), some other cutting methods may not have such great quality. To smooth the edges, the parts are put on a deburring machine’s conveyor belt. The conveyor runs through a series of brushes that guarantee a quality surface. The belts are wide enough to accommodate large parts.

Tumble Finishing

Metal tumbling is a surface treatment method where a metal part is put into a vibrating and rotating barrel. As the part moves towards the outlet, it slides through abrasive particles. It is used to burnish, deburr, clean, polish and brighten parts before applying the final finish. It is an economically sensible choice when there are enough parts to fill the barrel half-way full.

Powder Coating

A widely used method for painting metal parts, powder coating gives a wide range range of colours. In the process, a dry powder is electrostatically applied to a metal part. The next step is treating the parts with heat. The baking makes sure that the powder stays on the workpiece. The painted surface protects parts from corrosion and gives a nice look.

Wet Painting

The traditional way of painting by applying wet paint to parts. It is the right surface treatment method for metals that cannot be heated for powder coating purposes. Traditional paints have a wider range of colours and allow the application of a thicker coating. Also, it is more long-lasting in some circumstances where powder coating cannot perform.

Hot Dip Galvanising

Hot dip galvanisation Fractory

Hot dip galvanising, or just galvanising, is a process where a metal part gets dipped into molten zinc. Iron and zinc react, creating zinc-iron layers on the surface. Galvanised products have self-repairing properties. When damaged, they cover the unprotected area spontaneously. This makes it a great way to protect your metal parts.


Another way to coat a steel with a zinc coating is through electroplating.  An electric current runs through a saline/zinc solution. The electric flow goes through a zinc anode and a steel conductor. As a result, the conductor is covered with a protective zinc layer.


A surface treatment method suitable for coating aluminium and other non-ferrous metals. Ferrous metals are not suitable because of the formation of an iron oxide layer which flakes off, taking the anodised layer with it.

Aluminium, when exposed to oxygen, forms a layer of oxide. The principle of anodising is increasing the oxide layer’s thickness. This protects the metal from corrosion and wear but also provides a decorative layer. For further protection, a paint coating can be added.
