Info&Contacts

is a company specialized in aluminium products, starting from its early days as a supplier of reflector components for local Italian companies to its present position as a supplier to all the world’s major lighting system producers. This specialisation has led the Group to become one of the world's biggest producers of components for the lighting technology, solar energy industries and decorative market.

About

Performance Lab

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 with a proven record of durability; Almeco has been producing preanodized strip for lighting since 1982 and there are reflectors made from the original Sacall products still in use today.

Anodized & Pre-anodized

Without anodizing, untreated aluminium is prone to dirt pick-up, oxidation and staining and has inconsistent reflective properties. It is so easily scuffed and scratched that it cannot be cleaned without damaging the surface.

The bright anodizing process purifies the surface, enhances reflection and provides a hard clear coating that prolongs the life of the reflector almost indefinitely in normal indoor conditions and allows cleaning and lamp changes without damaging the surface.

Key characteristics

High total reflectance, ranging from 80% for matt finished products to 87% or more for the highest perfoming mirror grades
Excellent resistance to tarnishing and staining giving long product life
Availability in a wide range of surface finishes and also in different colours for decoration
Integrity of structure – the anodized oxide layer is formed directly from the metal and is therefore intimately bonded without danger of peeling or de-lamination
Light weight and easy formability for curving and folding reflector and other parts
Cleanability and low dirt pick-up
The products’ wear resistance allows reflectors to be cleaned as part of a planned maintained luminance programme
Temperature and fire resistance
Electrical conductibility allows use for earthing the reflector
