1.Aluminium alloy composition are mostly thin-walled hollow core section,easy to use,reduce weight,and the cross-section has a high flexural strenghth,makes doors and windows durable and small deformation.
2.Aluminium itself is easy to squeeze,cross-section dimensions of the profiles of precise machining accuracy.
optional waterproof,elasticity anddurability are relatively good sealing material,such as layering and silicone rubber sealant series.
In terms of the profile,various seal fixing groove,along with sections materail for the creation of favorable conditions. 
3.After the anodized aluminium surface treatment.can present the ancient copper,gold.silver and other colors,you can choose,through theoxidation and smoooth shine.
Sash frame is big,can insert large areas of glass,let in sunlight and bright,and enhance the facade between the actual situation of indoor and outdoor contrast,make the room rich layers.
4.Aluminium alloy oxide layer does not fade,not shedding,no paint,easy maintenance,no repairment.
