What are the characteristics of aluminum doors and windows?
Plastic doors and windows are different from the prominent features of aluminum doors and windows are two different materials, steel doors and windows aging is brittle, aluminum aging is oxidation.
"1, light, high strength: aluminum alloy material is mostly hollow core composite section, easy to use, reduce weight, and the cross section has a high bending strength, made of doors and windows durable, small deformation.
2, good sealing performance: aluminum itself is easy to squeeze, profile cross-sectional size accuracy, high precision machining.
Optional waterproof, elastic, durability are better sealing materials, such as rubber pressure and silicone sealant.
In the profile, a variety of sealing strip fixed groove, has been with the cross-section in the extrusion process together to complete the installation of sealing materials to create favorable conditions.
3, handsome appearance: aluminum alloy surface by anodized after treatment, can present the ancient lead of liver and copper. Gold, silver and other colors, can be arbitrarily selected, after the oxidation of bright and shiny.
Sash frame large, can be placed in a large area of the glass, so that the indoor light is bright enough to enhance the contrast between the internal and external facades, so that the room is more rich level.
4, strong corrosion resistance: aluminum alloy oxide layer does not fade. Do not fall off, no paint, easy maintenance, no maintenance.
