LIGHTING prenodized aluminium

Product catalog summary

Introduction
Pre-anodized aluminium has been a key material for fluorescent lighting reflectors for over 40 years due to its high reflection and durability. It is environmentally friendly and recyclable, with a proven track record of longevity.

Why You Need Anodizing
Untreated aluminium is susceptible to dirt, oxidation, and staining, which affects its reflective properties. Anodizing purifies the surface, enhances reflection, and provides a durable coating that extends the life of the reflector.

Product Structure
Almeco’s anodizing process includes degreasing, brightening, de-oxidizing, anodizing, and sealing. This process ensures a smooth, glossy surface with controlled coating properties optimized for lighting applications.

Key Characteristics

High total reflectance (80%-87%)
Resistance to tarnishing and staining
Available in various finishes and colors
Lightweight and formable
Cleanable with low dirt pick-up
Temperature and fire resistance
Electrical conductivity for earthing

Applications

Fluorescent lighting reflectors and louvers
Floodlight reflectors
Reflective ceiling panels
Switch plates and decorative trims

Pre-anodized aluminium Zavantem Airport Belgium Fluorescent lighting louver in internal office Nova Gorica ground Slovenia Introduction Pre-anodized aluminium has been the main reflector material for fluorescent lighting for the past 40 years and with good reason. It offers an excellent combination of high reflection and durability in a large range of finishes and qualities to suit most applications. Anodizing can be carried out economically without damage to the environment and reflectors are fully recyclable as the anodized layer forms only a tiny fraction of the product weight. It is a material...

Reflectivity characteristics Each material is characterised by three complementary reflective properties Specular Reflectance A measure of light reflected at an angle equal to the angle of incidence i.e. mirror reflection Diffuse Reflectance A measure of the amount of scattered light Total Reflectance This encompasses the total amount of light reflected from the surface as a percentage of the incoming light
