In general, plastic steel doors and windows are much lower in wind pressure resistance and watertight performance than aluminum alloy doors and windows due to their low material strength and low rigidity. Moreover, since the lining steel of the plastic steel doors and windows is not connected to the complete frame system at the corners of the inner cavity of the profile, the plastic welding angular strength of the window frame, the fan four corners and the dicing point is relatively low.
The aluminum door and window of the broken bridge is designed with a structural drainage system by using the principle of pressure balance. The sliding design is stepped with a slope, and the drainage port is provided. The drainage is smooth and the watertightness is good. At the same time, the aluminum frame and window frame of the broken bridge adopts hollow design, strong resistance to wind pressure deformation and good anti-vibration effect. It can be used in high-rise buildings and residential buildings. It can be designed with large-area window type and large lighting area . The airtightness of this window is better than any aluminum and plastic window, which can ensure the indoor window sill and floor of the area with large wind and sand without dust.
In addition to outstanding wind pressure resistance and waterproof features, the broken aluminum doors and windows also have the characteristics of strong sealing, good sound insulation and so on. Aluminum alloy doors and windows are now widely used in construction. Although the previous aluminum alloy windows have avoided some shortcomings of steel windows, the profiles themselves are made of metal materials, which have fast heat and cold conduction, and cannot solve the problems of sealing and heat preservation. At present, many door and window enterprises have developed aluminum bridges for broken bridge insulation, that is, the use of hard plastics in the middle of aluminum profiles to break the aluminum alloy, so as to achieve the same thermal insulation effect as plastic steel windows, and solve the problem of aluminum profiles. The problem of high thermal coefficient.
It is reported that the energy saving of broken aluminum doors and windows reaches about 50% . Broken bridge aluminum doors and windows have no worries about aging, no gas pollution. After the building reaches the life cycle, the doors and windows can be recycled, and the green environmental protection features are widely welcomed by the market.
Let the doors and windows face the typhoon safely
Before scraping the typhoon, be sure to close the window door and check if the lock is secure. It is best to use a towel or the like to close the window sash. Special attention should be paid to the large piece of fixed glass. Pay more attention to it, check if the window hinge is damaged, and if the screw is deformed or detached. Before the typhoon comes, it is necessary to check whether the glass glue is aging. If it is aging, change the glue in advance. Many people have not been prevented due to negligence, resulting in damage to doors and windows, and some will hurt people. If the typhoon is fierce, the aluminum window will show signs of scratching. Don't rush to the predecessor for control, but should retire and avoid it, and wait for the typhoon to find a professional to maintain.
Regardless of aluminum alloy and plastic steel, as long as it is a regular manufacturer, the quality is reliable and the installation is reasonable, it can effectively prevent wind. In the typhoon, the damaged doors and windows are mostly plastic steel doors and windows with fake counterfeit and aluminum alloy with insufficient thickness. The public must not look for a hardware store to be cheaper, should let the professional door and window business to issue a detailed plan, and then check the material on the Internet. Plastic steel windows should be selected genuine and best known brands ; the thickness of aluminum alloy should not be less than 1.2 mm. Especially the gravity support of the sun room directly affects its wind resistance and life.
