Light weight, high strength: aluminum alloy material is mostly hollow core thin-walled composite section, easy to use, reduce weight, and the section has high bending strength, made of doors and windows durable, small deformation.
Good sealing performance: aluminum alloy itself is easy to extrude, the cross-sectional dimension of profile is accurate, and the processing accuracy is high. The waterproof, elastic and durable sealing materials can be selected, such as rubber strip and silicone sealant series. In the profile, all kinds of sealing strip fixed grooves have been completed together with the cross-section in the extrusion process, creating favorable conditions for the installation of sealing materials.
Beautiful appearance: after anodizing, the surface of aluminum alloy can present ancient lead, liver, copper, gold, silver and other colors, which can be selected at will, bright and bright after oxidation. The window frame is large and can be inlaid with large area of glass, so that the indoor light is sufficient and bright, which enhances the contrast between the facade of indoor and outdoor, and makes the room more hierarchical.
No need to paint, no need to paint, no need to paint.
