PROPERTIES OF ALUMINIUM

Surface finishing using the anodising process

Our strength is particularly evident in the surface- finished version:

We offer anodising according to DIN 17611 for interior and exterior applications in the common anodising shades. Our standard coating thickness for interior applications is 10 - 12 μm. Please select the pre-treatment required for your application from Table 1. In table 2 you can find the standard anodised colours. Of course, we're also happy to supply you with special colours.

Table 1 – Surface finishing according to DIN 17611 / possible pre-treatments

	DESCRIPTION	SURFACE APPEARANCE	APPLICATION
E0	Without pre- treatment, anodised and compacted	Drawing marks, scratches, grinding grooves or other surface defects remain visible	Subordinate surfaces that are not in the field of vision
E1	Ground, anodised and compacted	Uniform, matt-looking surface, small drawing marks or scratches are eliminated	Decorative surfaces with clearly aligned structure
E2	Brushed, anodised and compacted	Uniform, bright surface, drawing grooves, scratches, filing marks only partially removed	Matt-gloss surfaces with a delicate structure
E3	Polished, anodised and compacted	Shiny surface, drawing marks, scratches, filing marks are only partially removed	Application preferably indoors, easy to clean, suitable for all colours
E6	Chemically pre-treated, anodised compacted	Matt, rough surface. Drawing marks, scratches, file marks partially levelled. Material-related changes in surface appearance are not always avoidable.	Inexpensive, suitable especially for dark - colourings
