ã€China Aluminum Industry Network】 Due to its low material strength and toughness, PVC doors and windows have lower wind pressure and watertight properties than aluminum alloy doors and windows. In addition to airtightness, the watertightness and wind pressure resistance of aluminum alloy doors and windows are better than those of steel doors and windows. Moreover, because the lining steel of steel doors and windows is not connected to the corners of the inner cavity of the profile, it is a complete frame system. The plastic welding angles of the four corners and the small squares of the fan are relatively low. The quick stacking door has many functions such as heat preservation and cold preservation, insect and wind prevention, dust insulation and sound insulation. Widely used in underground parking lots, industrial plants, food, textiles, electronics, printing and packaging, automotive assembly, precision machinery, logistics and warehousing and other places.

1. Attractive appearance After the surface of the aluminum alloy is anodized, the copper, golden, silver and other colors of the ancient lead can be displayed. They can be used at will, and they are bright and shiny after oxidation. The sash has a large frame and can be fitted with a large area of ​​glass so that the interior of the room is bright and bright, enhancing the contrast between the indoor and outdoor façade, making the room even more rich.
2. High wind pressure resistance, watertight performance Due to the low material strength and rigidity of steel doors and windows, its wind pressure resistance and watertightness are about two grades lower than those of aluminum alloy doors and windows. In addition to airtightness, the watertightness and wind pressure resistance of aluminum alloy doors and windows are better than those of steel doors and windows. Moreover, because the lining steel of steel doors and windows is not connected to the corners of the inner cavity of the profile, it is a complete frame system. The plastic welding angles of the four corners and the small squares of the fan are relatively low.
3. Good sealing performance The aluminum alloy itself is easy to be extruded. The cross section of the profile is accurate and the processing accuracy is high. Optional waterproof material, elasticity, and durability are all better sealing materials, such as rubber beads and silicone sealants. In terms of profiles, all kinds of sealing strip fixing grooves have been completed together with the same section in the extrusion molding process, which has created favorable conditions for installing sealing materials.
4. Lightweight, high-strength aluminum alloy materials are mostly hollow core thin-walled composite sections, which are convenient to use, reduce weight, and have high bending strength in cross-sections. The resulting doors and windows are durable and have little distortion.
5. Insulation performance Aluminum alloy insulation performance is not as good as steel doors and windows.
6. Strong corrosion resistance Aluminum oxide layer does not fade, does not fall off, do not need to paint, easy maintenance, no maintenance 7. Gas tightness slightly poor aluminum alloy doors and windows profiles higher dimensional accuracy, box, fan with tighter, but Plastic steel doors and windows are welded because of the frame and fan components, so their airtightness should be slightly better than the aluminum alloy doors and windows connected by screws, but the two are still at a grade level.
