Aluminum alloy surface is checked by qualityman to make sure it is clean without any deformities. Dies must be tested and corrected to high precision. The alloys are extruded to aluminum profiles of various shapes which depending on the dies used.

Anodizing Line
Anodizing is a process to produce aluminum oxide coating on the profile's surface, so as to protect it forms natural anodizing, thus enhance its hardness and durability against different weather conditions.

Powder Coating Line
Powder coating is a process to coat the aluminum profiles with a synthetic powder of a wide range of colors. Aluminum profile surface is degreased to remove oils and greases firstly. Any present oxide layer is etched by dipping the profiles in an acid activation tank. Profiles are then rinsed with deionized water to remove any remaining chemicals. Now the profiles are ready to undergo the chemical conversion coating.
