All about Aluminium

Tread plate / Checker plate / Floor plate / Durbar plate

The tread plates are mainly used for stairs, steps and floor coverings. According to its structure and dependent on the field of application the following kind of tread plates can be distinguished: 

• 2-bar checker plates and
• 5-bar checker plates.

The aim of the anodizing process is to increase the corrosion resistance of aluminium and to get an aesthetic surface. During the process the thickness of the natural oxide layer of the metal is increased artificially. Consequences:

• The oxidation process stabilizes, the oxide layer can protect the aluminium even for decades. 
• The surface gets much more aesthetic which is important especially for ornamental elements and surfaces.
• The anodized surface can be dyed into many different colours. This surface has a better resistance in comparison to lacquered surfaces. 
• The ability to reflect heat and light increases by anodizing which is an important property for manufacturing light mirrors and radiators. 
• The hardness on the surfaces increases which is particularly in the production of machine parts of great benefit. 
• The quality of engraving improves.
• In case of aluminium wires ceramic surface is formed as a consequence of anodizing which is an excellent electrical isolator. 

• The aim is not only decorating, however, also to provide corrosion resistance and to increase wear-resistance.
• On the surface of aluminium sheets an artificial oxide layer is produced that can be painted during the anodizing process by using organic dyes and non-organic salts. The painted surface is sun and heat-resistant as well as wear-resistant.
