2. 7-stage pretreatment in a 65 meter long washing tunnel
The quality of the powder coated surface is already done in the pre-treatment phase. Our revolutionary 65-meter, 7-stage, pre-treatment production line prepares your product for powder coating in a never before seen way in this industry. Great pre-treatment guarantees the durability of the paint surface.
Pre – treatment steps
3. Drying
Water on the surface of the product causes the powder coating to boil. Therefore, after the pre-treatment phases, your product ends up in a state-of-the-art 20-meter long drying oven that dries the parts to be painted very carefully for painting.
4. Powder coating in an automatic painting cabinet
The powder coating paints used for painting metal surfaces are sprayed on the surface and painted using compressed air.
Our powder coating cabinet is completely custom-made for us and designed together with VTT (one of Europe’s leading research institutions), It enables e.g. Finland’s fastest color changes.
Our automatic powder coating cabinet paints with precision and, if necessary, our painter completes the powder coating of your product(s) by hand.
5. Polymerization of the paint, ie baking in a powder oven
The typical parameters of our 30-meter baking oven are 160-220 degrees / 20-30 minutes.
Electrostatics fix the paint, and after the oven, the paint surface becomes very wear and shock resistant. Any scratches or abrasions that may occur later during the installation phase of your product can be easily removed with car wax or fine water-based sandpaper and wax.
6. Quality Inspection
We inspect the overall and visual quality of the product, as well as, check the paint adhesion and measure the thickness of the paint film according to the customer’s wishes and selected the quality package. 8 different measurement methods are available. Afterwards, we’ll fill up the necessary quality control documents.
7. Packaging (and assembly)
The Packaging and finishing according to the customer’s instructions. As an additional service we offer, for example, thread opening and assembly.
8. Fast Shipping
You will receive your carefully finished product within 1-5 business days of its arrival to us.
As a VIP service, we also offer a Fast Track Service. Ask More.

We will help you choose the best powder paint for your application
The powder paint is always selected according to the application. Severe climatic conditions and harsh physical or chemical stress naturally have stricter requirements on the powder coating than clean interior use, for example.
Our professional staff are always happy to help you choose the right powder coating for you application, as well as answer questions about color availability and matching, and more.
We paint all the most common metals and other surfaces
Powder coating is best suited for metals such as steel, aluminum and galvanized steel (including hot-dip galvanized steel). However, thanks to the advanced technology in the field, it is also possible to paint other surfaces with certain reservations.
Steel
Steel is a popular and fully recyclable material, but is corroded by oxygen and moisture. Therefore, it should be protected from rust. Stainless steel is especially suitable as a material for wet and humid conditions. Due to its weather resistance, it is a popular material for facades, for example.
Aluminium
Aluminium is more expensive but significantly lighter than stainless steel. It is thus a common material, especially in the construction industry and vehicles. Typical applications include wall and window structures as well as glazed structures, facades and coverings, wall panels and partitions, ventilation and heating equipment, and boats, ships, trains, cars, bicycles, airplanes, and space shuttles.
Galvanized Steel
(also HDG)
Zinc-plated a.k.a. galvanised steel is a cheaper material than stainless steel. However, it is less shiny or even on the surface and is more challenging to clean. Powder coating improves the appearance of the zinc coating. In addition, powder coating extends the life of galvanized steel – which of course applies to all materials to be painted.
Hot-dip galvanized steel is resistant to salt water, so it is commonly used especially in the ship building industry. Other applications include street poles and railings and fences.
Other Materials
The Modern technology also makes it possible to powder paint multidimensional objects. With certain reservations, we can powder paint wood, plastic and composite products.
Maximum dimensions of the powder coated product:
Width: 1 150 mm | Height: 2 100 mm | Length: 6 600 mm (even 9 100mm with certain reservations)
The most common binders for powder paints
EPOXY POWDER
Epoxy powders are suitable for paint coatings in the metal industry for products stored indoors that require chemical resistance, such as resistance to acids and alkalines. Epoxy powders are well suited for special applications in the heavy metal and chemical industries.
EPOXY POLYESTER POWDERS
Epoxy polyester powders are best suited for interior applications that require mechanical strength. Epoxy polyester powders are also a cost-effective choice, as their short paint time is also reflected in the price.
POLYESTER POWDERS
Polyester powder is a very common powder paint as it is suitable for both indoor and outdoor use. Polyester powders are suitable for use e.g. in the metal industry product painting for outdoor applications where good weather resistance and yellowing resistance to heat and UV light are required. For demanding conditions, a corrosion-resistant painting system in accordance with the standard SFS-EN ISO 12944-2 environmental classification is selected.
POLYURETHANE POWDER
Polyurethane powders are suitable for products whose surface must be highly resistant to mechanical and chemical wear. Polyurethane powders have good UV protection, which means that they are ideal for outdoor applications. Applications can be, for example, forestry and field machines, bicycles and other vehicles. They are also used in anti-graffiti paints.
Special Paints
ANTIBACTERIAL PAINTS
Bacteria and microbes on the surface of the antibacterial paint are quickly destroyed. A surface treated with antibacterial paint passes even the strictest hygiene level criteria, and thus common applications include kitchens, hospitals, laboratories and other research facilities.
ANTI-GRAFFITI PAINTS
nti-graffiti paints are very resistant to even strong solvents without damaging the paint surface. Therefore, they are used in areas where it is desired to facilitate the cleaning of potential stains.
SUPER DURABLE PAINTS
Super Durable powder coatings are extremely resistant to weathering, UV radiation and mechanical wear, among other things. These powder coatings are therefore well suited for the construction industry, (play) parks and fences, as well as the ship, train and automotive industries.
LACQUERS
Powder lacquers are also available in color.
HEAT RESISTANT PAINTS (SILICONE PAINTS)
Silicone powders are used in products whose coatings must withstand higher than normal temperatures. Typical applications are, for example, heaters, grills, exhaust pipes and fireplaces.
PRIMERS, ZINC AND EPOXY PRIMERS
Zinc improves corrosion resistance. Zinc-based primers are especially suitable for applications whose long life cycle could otherwise be shortened by harsh climates.
ELECTRODUCTIVE POWDER PAINTS (ESD)
Electrically conductive or ESD powder paints are antistatic and are especially suitable for areas where static electricity can cause problems. ESD paints are used in the electronics industry, for example.
Surface Qualities
HAMMER PAINT
Hammer paint is a special metallic lacquer paint suitable for indoor and outdoor use, which is also suitable for wood surfaces with reservations. The hammer paint, as the name implies, forms a surface that conforms to hammered enamel and is highly resistant to corrosion.
STRUCTURAL PAINTS (SAND PAPER AND ORANGE EFFECT)
Structural paints give interesting effects to the surface. They are suitable for both outdoor and indoor use and are commonly used in electronic products and furniture, among other things.
METAL AND PEARL PAINTS
The range of metallic and pearlescent paints is comprehensive. Ask for more details.
Gloss Levels
Glossy 85-95%
Semi-gloss 65-80%
Matte 20-30%
Supermatt 1-5%
Almost all gloss levels are possible when made separately.

We’ll powder coat your products beautifully and efficiently.
What you should consider when preparing your product for powder coating?
The powder coating finishes the surface of your product beautifully. However, it does not fix and fill the shapes of your product. In other words, if your product has possible surface unevenness or other imperfections, the powder coating will not be able to fix them. So always remember to prepare and finish your product carefully for painting. For example, if your product has visible unfinished welds or any other imperfections before the powder coating, they will still be visible after the powder coating.
