What kinds of profiles are made of aluminium alloy windows?
Four, look at the materialMaterial in the material, there are 6 main areas of reference:The thickness: Aluminum Alloy sliding window of 70 series, 90 series two, Aluminum Alloy housing interior sliding doors with 70 series. The number of aluminum alloys indicates the number of millimeters of the thickness of the door frame. Common aluminum alloy sliding window has 55 series, 60 series, 70 series, 90 series of four kinds. Selection should be based on the window size and the local wind pressure value is determined as shall be not less than 70 series Aluminum Alloy closed balcony sliding window.The strength: tensile strength should be 157 per square millimeter of Newton, yield strength to reach 108 per square millimeter of Newton. When buying, you can moderate bending profiles, and then you should be able to restore the original state.3: the same color Aluminum Alloy profile color should be consistent, such as color, that is not to buy.The flatness: check the Aluminum Alloy profile surface, should not sag or bulge.The gloss: avoid buying Aluminum Alloy doors and windows opening on the surface of the bubble (white) and ash (black), crack, burr, profile leather and other obvious defects.The oxidation degree of oxide film thickness should reach 10 micron. When choosing, light the surface of the profile to see if the oxide film on the surface can be removed.
Very simple outline of the material: square tube (Fang Tiao), winger, on the slide, down the inner frame of the material: hook enterprises, light enterprises, the upper cross, lower cross
Now do window three. Aluminum Alloy. Plastic. Frameless glass. Plastic fake too much. But for a long time will look a bit dirty. Frameless glass to Water Leakage. Aluminum Alloy you ask a little better. But the price is slightly more expensive. But more practical. As for this profile the course is Aluminum Alloy. Nothing special distinction.
If the outer frame is used, slide, slide and seal;Internal fan, then use the upper horizontal, lower horizontal, hook enterprises, light EnterprisesThis is used for ordinary sliding windows and sliding doors. If the window is bright, use the layeringFour open the window, but also in a spell, in fact, there are some materials, but not commonly used, so do not say moreIf you do casement window, it depends on what you want to do,
