Aluminum Extrusion Profile

In addition to supplying natural stone, we specialize in crafting custom aluminum (or 'aluminium' in British English) extrusion profiles designed specifically for construction-related applications. These profiles undergo meticulous manufacturing and are subjected to a high-quality anodization process.

Aluminum Extrusion

Aluminum alloy parts and profiles are produced either through die-cast or a designed extrusion die. The most widely used raw material no. of aluminum for building industry is 6063-T5.

Aluminum bars serve as the primary raw material for aluminum profile extrusion.
We maintain a stock of extended aluminum bars in preparation for profile extrusion.

Aluminum Metalworking Process

Metal fabrication is the process of transforming raw or semi-finished metal materials into final products through cutting, shaping, or molding.

Specialized metal fabrication work is typically carried out in fabrication shops (fab shops). Common fabrication methods include cutting, drawing, folding, forging, machining, punching, shearing, stamping, and welding, which are employed to reshape or create new products. Fab shops also offer finishing services like deburring, polishing, coating, and painting to enhance the final product's quality.

Aluminium Anodizing & Dyeing

An anodized finish is a clear or colored coating chemically applied to the surface of aluminum. This anodizing process not only enhances the thickness of the natural oxide layer on aluminum parts but also shields them from corrosion. Furthermore, anodizing alters the crystal structure near the surface of the aluminum alloy, enabling us to impart vibrant colors to the metal.

Depending on the size and intended use of the aluminum alloy component, the anodizing process can be categorized into two methods: 'long-profile anodizing' and 'small-widget anodizing.'

Long Profile Anodizing

We anodize long profiles by stacking them in a large metal basket.
The metal basket is submerged in a sizable oxidation pond with chemicals.
Aluminum profiles are typically immersed in the oxidation pond for approximately 20 to 40 minutes.

Small Widget Anodizing

In the anodizing of small aluminum parts, there is often a need to anodize multiple sides of the components, which necessitates the use of specially designed stands to securely hold the metal parts during the anodizing process. Additionally, in the dyeing process, the aluminum alloy parts can be colored to a specific hue.
