Aluminum Extruded Shapes
The
Aluminum Extrusion Process enables an almost unlimited variety of
cross-sectional profile to be formed, which can lead to more economical and
faster production of various end products by reducing the weight and number of
components and parts required.

Standard Tolerance
Due to the nature of the metal and the
extrusion process, all extruded shapes are subject to slight dimensional
difference at various point against actual specified in the finished products
The general standard commercial
tolerance for cross-sectional dimension, surface flatness, twist and
straightness are available on request.
Surface Finishing
Almost
all aluminum surface can be treated to a variety of physical and chemical
process to improve their overall appearance and / or increase their resistance
against corrosion and weathering.
For architecture applications, one of
the most common type of surface finishing is the anodized finished. This is
basically a layer of aluminum oxide film deposited on the metal surface through
an electrolytic oxidation process.
The anodizing process can also add a
range of colors in shades of Bronze and Black for further aesthetic effects to
the aluminum surface. Other types of surface finishing that are gaining
popularity in the market are Electro-Deposition Surface Finishing (ED), Powder
Coating and Fluorocarbon. Chiang Jiang has been recently promoting ED surface
finishes as a substitute for the conventional finishes for buildings requiring
high aesthetics and long durable finishes (especially good for buildings near
the sea where the saline environment could be harsh on anodic coatings)
