Extruded aluminum window frame profile are generally divided into flat Windows, flat doors, sliding Windows, sliding doors four big series.There are mainly 38 series and 50 series of flat Windows;The flat door is divided into 50 series and 70 series;Push-pull window is divided into 80 series and 90 series;Sliding doors are mainly 90 series.

The extruded aluminum window frame profile surface that makes door window can adhere different color, its function lies in: adornment, anticorrosive, resist ageing, weatherability.Can be divided into:
Anodic oxidation -- relatively easy to fade and poor adhesion;
Electrostatic powder spraying - strong weather resistance, color stability, good adhesion, has been widely used;
Fluorocarbon spraying - weather resistance, aging resistance, adhesion is far better than electrostatic spraying, but the cost is also far higher than electrostatic spraying;
Electrophoretic coating -- its adhesion, brightness and other properties are relatively stable, but the cost of surface treatment is also high.
Wood grain transfer - film thicker, better look and feel.
