What are the maximum dimensions of elements for powder coating?

The maximum dimensions of elements we are able to powder coat result from the working dimensions of our oven and are 3000 x 1700 x 1000 mm. For atypical or complex structures, please contact us directly.

What colors, textures, and gloss levels are available in powder coating?

We offer a full range of colors from the RAL and NCS palettes. The customer can choose the gloss level (matte, semi-matte, satin, gloss, high gloss) and the finish texture (smooth, fine or coarse texture, antique, metallized, crocodile skin effects).

How is metal prepared for powder coating at ELMAL Sp. z o.o.?

Surface preparation is the key to coating durability. We use mechanical cleaning (shot blasting, sandblasting to remove rust, scale, and old paints) and chemical treatment (degreasing, phosphating). For steel elements, we also apply anti-corrosion primers.

What is the DUPLEX system and when is it worth using?

The DUPLEX system is a combination of galvanisation (hot-dip or electro-galvanised) with powder coating. This provides double corrosion protection for steel structures. Zinc protects steel from rust, while powder paint protects zinc from oxidation and gives the desired appearance. It is recommended for elements used outdoors (gates, fences, balustrades).

How does powder coating differ from traditional wet painting?

Powder coating creates a thicker, more uniform, and significantly more abrasion, impact, and chemical resistant coating than wet painting. In addition, it is a faster process (the element is ready for assembly immediately after cooling down from the oven) and eco-friendly (no solvent emissions).

Can galvanized or aluminium elements be powder coated?

Yes, we successfully paint both aluminium elements and galvanized steel. However, this requires appropriate outgassing processes in the oven and chemical surface preparation to prevent bubble formation and ensure excellent paint adhesion.

Powder Coating

The coating process

Applied as a free-flowing, dry powder. Electrostatically charged particles bond with the metal surface of the element, forming a strongly bound coating that protects the element from corrosion. Cured at 180-220°C, the paint layer is significantly more mechanically resistant than traditional paint, ensuring the decorative effect remains for many years.

Eco-friendly

Powder paints belong to the group of ecological coating products. They do not contain organic solvents, and during their application, no harmful volatile substances are released into the atmosphere. Therefore, the entire coating process is safe for the environment.

Why choose powder coating over traditional paint?

The technological process allows applying a paint layer in the range of 60–240 μm. Unlike traditional painting, the paint does not peel or flake off. A thicker paint layer is more resistant to abrasion and scratches. Besides, the finish of the element is smooth and uniform over the entire painted surface. In addition, beyond a very wide range of colors (RAL, NCS), powder paint manufacturers offer special decorative effects such as textures, mottling, and veins.

How does powder coating work?

Discover the complete powder coating process from the perspective of physics, chemistry, and materials engineering. In this article, you will learn how electrified paint particles deposit on metal, how polymerization occurs in the oven at high temperatures, and why this method provides unrivaled corrosion protection and weather resistance.
