ANODIZING

Durability with a Touch of Elegance

Anodizing solutions that offer both protection and elegance.

ANODIZING

Anodizing is the process of thickening the natural oxide layer on aluminum surfaces in a controlled manner. This enhances resistance to external factors while giving the material an aesthetically pleasing appearance. At EAS Aluminium, we offer anodizing in various thicknesses and colors, meeting the technical and visual expectations of different sectors.

Thanks to anodizing, our products gain superior corrosion resistance, longevity, and environmental durability. With finishes ranging from gloss to matte and unique color effects, we add aesthetic value to architectural applications. Our anodizing operations are carried out with a strong focus on environmental sustainability, with careful waste management throughout the process.

How EAS Anodizing Works

An eight-step anodizing workflow — from surface preparation to export-ready profiles — designed for architects, fabricators and industrial buyers.

01
Profile Receipt
Incoming extruded or customer-supplied profiles inspected for surface condition and dimensions.
02
Pre-treatment
Degreasing, cleaning and surface preparation to remove oils and contaminants.
03
Racking
Profiles mounted on racks for uniform current distribution through the anodizing bath.
04
Anodizing
Controlled electrolytic oxide layer formation in sulphuric acid bath — film thickness to specification.
05
Coloring
Optional electrolytic or absorption colouring for bronze, black or architectural tones.
06
Sealing
Hot-water or cold sealing to close pores and lock in colour and corrosion resistance.
07
Quality Inspection
Film thickness, appearance and dimensional checks before release.
08
Export Dispatch
Anodized profiles labelled, protected and shipped from Svilengrad to EU and regional markets.

FAQ

Anodizing — Questions & Answers

What is aluminium anodizing?
Anodizing is an electrolytic process that thickens the natural oxide layer on aluminium, improving corrosion resistance, surface hardness and appearance.
Which anodizing finishes does EAS offer?
We offer natural clear anodizing plus coloured finishes including bronze and black tones for architectural and industrial applications.
What oxide layer thickness can you achieve?
Typical anodic film thickness ranges from 5 to 25 µm depending on project specification, alloy and end-use requirements.
Can you anodize profiles extruded elsewhere?
Yes. We can anodize customer-supplied profiles subject to surface condition, alloy compatibility and pre-treatment requirements.
What is the difference between anodizing and powder coating?
Anodizing creates a metallic oxide layer integral to the aluminium; powder coating applies an organic paint film. See our powder coating page for comparison.
Which alloys are suitable for anodizing?
Architectural and industrial alloys in the 6xxx series are commonly anodized. Contact us with your alloy specification for confirmation.
Do you provide quality certificates?
Yes. EAS operates under ISO-based quality management with Qualanod standards and documented inspection — see quality & certificates.
How do I request an anodizing quote?
Share your profile drawings, alloy, finish colour, quantity and delivery destination. Our team will respond with lead time and pricing.
