Now building, doors and windows are what materials do? Aluminum is not to be eliminated?
Features of aluminum alloy doors and windows profiles:
1. Light weight, high strength
???? Aluminum alloy material is mostly hollow core composite section, easy to use, reduce the weight, and the cross section has a high bending strength, made of durable doors and windows, deformation small.
2. Seal better
???? Aluminum alloy itself is easy to squeeze, profile cross-sectional size is accurate, high precision machining. Optional waterproof, flexible, durability are better sealing materials, such as rubber pressure and silicone sealant. In the profile, a variety of sealing strip fixing groove, has been with the cross-section in the extrusion process of the same completion, to install the sealing material to create favorable conditions.
3. handsome appearance
???? Aluminum alloy surface by anodic telephone processing, can be colored, can be arbitrarily selected, after the smooth and shiny oxidation. 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 oxide oxide layer generally do not fade, do not fall off, easy to change, easy maintenance, no maintenance.
Restricted is the aluminum alloy doors and windows is always the mainstream of the building, but the choice is different.
Now the pillars, Kennedy is a good brand.
Of course, the so-called ecological doors and windows are also good, but mostly aluminum.
