POWDER COATING - MORE THAN 3,800 AVAILABLE COLOURS.

Surface coating of profiles provides both corrosion protection of the metal and a decorative appearance. For finishing aluminum surfaces, the following two possibilities are offered: 

Anodizing and powder coating.

Powder coating is a popular method for surface treatment of aluminum parts. After pretreatment, an electrically charged powder coating material is applied to the aluminum and is subsequently bonded. Thus, the method is absolutely free of solvents and resources. The colours can be selected from standard colour catalogues.

There are more than 3,800 colour selections in the following catalogue:

Pulverbeschichtung mit RAL Classic

RAL-Classic indicates the classic RAL colour collection. RAL-Classic is the oldest colour collection known in Germany. It is based on the colour list from 1927 and contains 213 colour tones today. The colours are marked with a 4-digit number (i.e. RAL 9006) as well as a name (i.e. White Aluminum).

Pulverbeschichten mit RAL Design

RAL-Design is a newer colour system. The classification of these colours derives from the following criteria: (colour) hue, brightness, and variegation. A 7-digit colour number is given for the values for these colour traits (i.e. RAL 260 30 35). The RAL-Design colour system from 1993 was edited in 2007. Today, it contains 1,625 colour tones.

Pulverbeschichten mit NCS

NCS "Natural Colour System" is a colour coding system, which relates to the way people see colours. By using NCS colours, all conceivable surface colours can be delineated and furnished with an NSC-identifier. The catalogue contains 1,950 NCS standard colour tones.

Pulverbeschichten mit DB-Farbtonkarte

The “DB-Standard Colour Chart” includes colour s that are used by the Deutsche Bahn (German Rail System). These colours, in contrast to the RAL-Colour Systems, contain a metallic effect pigment. There are 14 colours in this catalogue.

 

The creation of additional colours is possible by means of sample mixing from powder suppliers. The degree of gloss must also be observed along with the colour shades. Degrees of gloss are as follows:

matte, silky gloss and glossy.


Lighter colours should be used in order to obtain lower emission values. Dark colors absorb more solar energy. As a result, surface temperatures of the mechanical components are higher. 

Attractive contrasts can be achieved by mounting single lamellas in a different color tone. Examples would include the overlying or forward most lamella.  

This also relates to the substructure, construction stages or other parts of buildings.

Recommendation for practical application:
We advise against mill-finished materials. Due to the fact that colors vary from supplier to supplier, sample plates are recommended. Or, a supplier for the color powder should be agreed upon assignment.
