Elvial - THE DESIGN
Well Being
Τhe choice of aluminum systems today provides Safety and Energy Efficiency, improving everyday living. The right colour may uplift the aesthetic result and add value to the building image. It also contributes to the well-being of everyday users.

Aluminium = Color
No other architectural building material offers the almost unlimited color range of aluminium. There are 2 basic technologies developed for surface treatment:
Elvial - THE DESIGN
Powder Coating
During powder coating, the aluminium surface is “passivated” through the application of a chemical pretreatment process with chrome free chemicals.
Coating with a layer of polyester powder then follows, giving the final color hue and texture to the aluminium. Powder Coating allows for full creative freedom, offering an unlimited color pallete in hue and texture.
Anodizing
Anodizing is an electrochemical process during which, the aluminium surface transforms into a layer of inactive, cohesive and hard oxide. As a result, the “passivated” surface of the aluminium functions as an impenetrable protective shield, over adverse environmental conditions.
The anodic coating is transparent and its structure allows the incorporation of pigments for the coloring, however, in limited color hues. Anodizing can safeguard the metal but it tempers the coloring options and is rather costly.

THE ISSUE

Filiform corrosion is the corrosion appearing on the metal surface and under the coating.

Filiform corrosion is mainly detected in coastal and island locations, as well as in residential compounds and hotel establishments with a burdened environment.

It is caused by the reaction of the aluminum material in acid environment conditions, such as:
  • Coastal areas, up to 25 km from the shore.
  • Areas neighboring to highways, which during the winter season “accept” quantities of sodium chlorides to prevent icing.
  • High humidity environment, like spaces with a pool, sauna etc.
Filiform corrosion usually appears in the form of “bubbles” and starts most of the times from the frame corners.

If appearing
It does NOT stop, and it gradually ATTACKS the
whole metal surface. There is NO treatment and
full frame replacement is needed!
Pre-anodizing

The solution to the filiform corrosion is given by the Pre-anodizing.

It is, actually, the creation of a firm 3-8 mm oxide coating, which is produced under controlled conditions, similar to those of a typical anodizing, but without the final finishing phase. This coating penetrates the aluminium surface and works as an ideal foundation layer for the powder grid that will follow with the Powder Coating, offering maximum anti-corrosion protection.

This way, choosing Pre-anodizing over the classic pre-treatment methods, we achieve the absolute combination of both 2 different surface treatment methods

  • Total freedom in color hue and texture choice
  • Maximum Anti-corrosion Protection

The Restrictions
W77AI2.ML_BS
Pre-anodizing, as a pretreatment process, ensures excellent results ONLY if:
  • The powder coating is IMMEDIATELY applied after the pretreatment process of pre-anodizing
  • WITHOUT human intervention, as pre-anodizing DOES NOT block porous materials and
  • In a STERILE ENVIRONMENT, free of suspended or other particles that diminish the result
Traditionally, until today, the Pre-anodizing process – wherever applied – takes place in Anodizing facilities and, then, the products have to move to Powder Coating facilities. However, this process demands thorough movements’ coordination while unpredictable factors may arise, burdening the waiting time until the POWDER COATING application:
  • Delay on the products’ removal from the Anodizing facilities.
  • Long products’ standby (queue) at the Powder Coating.
  • Exposure of the Pre-anodized products to dust and humidity during the transfer.
  • Increased risk of corruption of the pre-anodizing advantages due to contact with trimmings and human skin.
Therefore, the time between the completion of the Pre-anodizing and the POWDER COATING application, is determining for the achievement of Maximum Anti-corrosion Protection. However, the avoidance of contact with the human skin and the environment where the products are being processed until the painting are even more vital.

Zero Waiting Time.
Spotless Environment.
Robotic Handling.
This is what
ELVIAL Pre-Anodizing 2IN1
is all about

ELVIAL owns the first in Greece and one out of seven worldwide, fully automated serial pre-anodizing and powder coating lines. ELVIAL Pre-anodizing 2in1 facility is robotic. No human hand meddles with the materials; the production environment is free of dust and other aggravating factors.

The profiles are subdued to an electrochemical procedure identical to that of anodizing. The aluminium profiles are placed in an underground tunnel and submerged in a sulfuric acid solution. Pre-anodizing produces an anodic substrate on the surface of the aluminium profile that protects it from corrosion. Then the profiles are serially painted, eliminating waiting time, whilst the pores on the aluminium surface of the profile are completely sealed.

In brief, ELVIAL PRE-ANODIZING 2IN1:

  • Is the SOLE METHOD that ensures MAXIMUM PROTECTION from filiform corrosion
  • Offers COUNTLESS COLOR CHOICES and a wide range of texture, polishing and effects.
  • Is factory QUALITY ASSURED
  • Pre-anodized aluminium profiles are automatically categorized as SEA PROOF PLUS.
ELVIAL PRE-ANODIZING 2IN1 IS UNIQUELY COMBINED with
Class 2 [Super Durable] powder coatings.
Thanks to the robotic handling of the products and the eliminated waiting times, with the ELVIAL Pre-anodizing 2IN1, you are now sure.
Our COLOR COLLECTION

Colors can be playful and eye catching. They can be soothing and encompassing. The hues and textures are of utmost importance because they highlight the design. We form them keeping in mind prominent architects' preferences and international trends.
