The System VS Ordinary Doors & Windows Which Is Better? Facebook Twitter LinkedIn Pinterest Telegram Email 1. The technology is different We all know that door and window enterprises are not producers of doors and Windows, but assemblers of door and window accessories. The quality of aluminum doors and Windows depends more on the splicing strength and sealing of accessories. The traditional Angle group process of ordinary doors and Windows is used to extrude aluminum Angle code + Angle impact connection, and then apply sealant on the knife edge of the extrusion Angle, and the real need to seal the aluminum profile joint does not have sealant, and rain water will enter the inside of the door and window through the splicing capillary seam, such a process cannot guarantee the tightness of the Angle group and the sealing of the joint. The system doors and Windows are different, it uses a special cast aluminum corner code with hollow stainless steel pins + glue. It has two advantages over the traditional process, one, expansion tensioning fixed technology, two, glue sealing technology. Each cast aluminum corner code is composed of two pieces of cast aluminum, when the stainless steel hollow pin into, the two pieces of cast aluminum will automatically open, plus the corner code pin hole and profile pin hole with tolerance, the two 45 degree splicing profiles firmly tight, fixed. After fixing, glue should be injected into the corner code through the injection hole of the pin. After the completion of gluing, the 45 degree joint of the profile is completely sealed with glue from the inside of the cavity. In this way, the gap between the corner code and the profile cavity is completely sealed, effectively ensuring the good air tightness of the doors and Windows of the system. 2. Stability and performance The system doors and Windows have an independent technical department, which will conduct strict testing and inspection of each component to ensure the stability of doors and Windows. After 2 to 3 years of research and development of the system doors and Windows, the performance and quality of the material, the whole door and window are comprehensively tested, and the mature products are launched after reaching the expected goals. Ordinary doors and Windows are assembled according to their own needs to order different parts, due to the different quality of each part, different performance and other factors, resulting in relatively poor stability in the process of use; Moreover, it is a temporary integrated door and window product for a single project, which is often not fully tested. 3. In terms of flexibility System doors and Windows are serialized, standardized products, each component is fixed according to different performance, notch structure, material supply, etc., has a strong exclusibility and incompatibility, is based on the needs of the project to choose a series, flexibility is small, but now is the era of customization, system doors and Windows can be designed according to customer needs applicable door and window products. Ordinary doors and Windows can be configured according to their own needs, door and window materials can be selected by domestic and foreign manufacturers, and can also be temporarily opened, with strong flexibility, but its quality and standardization can not be guaranteed. 4. Software and after-sales service System doors and Windows provide products at the same time, but also provide design software, design manuals, procurement manuals, processing manuals, professional equipment and technical service support, is a complete industry chain. In terms of after-sales service, the quality assurance of the system doors and Windows is not only the engineering quality assurance of the doors and Windows unit, but also the life warranty of the system company’s products. In addition, brand stores can carry out simple repairs. The quality of ordinary doors and Windows depends on the level of designers and the processing and installation capacity of doors and Windows enterprises, and is relatively insufficient in terms of help support and follow-up services. At the same time, ordinary doors and Windows are often after-sales doors, and the owner does not know who to find to repair the doors and Windows after the failure. In the eyes of the average person, a door and window with a slightly better material is a system door and window. In the eyes of some door and window shops or designers, as long as the designed doors and Windows are system doors and Windows. When we choose doors and Windows, we can choose system doors and Windows to keep up with the pace of The Times. Facebook Twitter LinkedIn Pinterest Telegram Email

9 Doors And Windows Hardware Facebook Twitter LinkedIn Pinterest Telegram Email Hardware accessories are the heart of doors and Windows, not supporting roles! The proportion of hardware cost in a door and window will not be too small, good door and window hardware cost accounts for 15%-30% of the overall cost of doors and Windows, so the purchase of door and window hardware is also very important for the owner! First, door and window hardware accessories in addition to meet the physical properties of doors and Windows, mechanical properties, but also meet what conditions? Easy to operate, single point control: by changing the position of the handle to achieve a variety of opening functions; Standardization and serialization, so that door and window enterprises and construction companies can quickly install; Adjustability; Strong bearing capacity; High safety; Widely used; Strong applicability (high quality specifications) Second, door and window hardware accessories should be how to choose and calculate? When choosing hardware accessories, try to choose products with guaranteed quality, the quality level of hardware accessories should be consistent with the quality level of doors and Windows, the structure and shape of hardware accessories should be consistent with the profile, the color coordination and beauty, the function is correct, the operation is flexible and the installation is convenient.  The installation of hardware accessories should be complete, standardized, reliable, and accurate. After installation, the doors and Windows are beautiful in appearance, flexible and convenient to open, without deformation, obstruction and collision. Exposed fasteners of hardware accessories should be preferred stainless steel products. Multiple locking points should be used when the flat doors and Windows and the large sliding doors and Windows are closed, otherwise the air tightness will be greatly reduced under the action of negative pressure difference, taking into account the convenience of operation, it is best to use multiple locking points to handle or drive Three, casement window sash installation how wide is appropriate? What are the disadvantages of installing oversized sashes? Some owners like large window sashes, think that this ventilation effect is good, in fact, the larger window sashes and smaller ventilation effect is not much different. What are the disadvantages of having a large window sash? First, the window sash is too heavy and increases the load of accessories such as slide stays, hinges, and hinges, increasing the friction, shortening the service life of accessories, and also increasing the resistance of opening and closing. Second, when the window sash is opened and closed, the hand lock stroke is increased, and the arm needs to be extended more, which will also increase the difficulty of opening and closing and increase the danger. Generally, the width of the window sash is more suitable in 60-65cm Four, the door and window handle position how high appropriate? The position of the casement window handle lock is best explained when placing an order, so as to adjust the parameters in the design and processing, after all, it is customized according to the specific situation of the owner. In general, the height of the hand lock from the ground should be near the shoulder position of the female owner, usually about 1.4 meters, if the female owner is tall, it will be raised. Fifth, the poor quality of the slide stay will be loose for a period of time, and serious cases will lead to the sash falling off and resulting in safety hazards. What are the requirements of high quality slide brace in terms of material? The slide brace must be anti-rust, because if it rusts, it will affect the smoothness of sliding, and reduce the mechanical properties of the slide brace, which will lead to fracture. To have good corrosion resistance, it is necessary to choose a high grade 300 series of stainless steel, such as 304 stainless steel, this kind of stainless steel has high corrosion resistance, and high strength and toughness, and the low grade of 2-character stainless steel such as 201, 202, although the price is low, but the corrosion resistance is lower than 300 series. And No. 304 stainless steel has high wear resistance. In addition, the thickness of the slide brace also affects the bearing capacity, and it is best to choose a slide brace with a thickness of more than 2.5 when the window sash is heavy. Six, why the hinge after a period of time there will be oil exposed? After a period of operation, the viscosity of the oil added inside the hinge is reduced and it is easier to flow out; At the same time, the hinge core and the scroll, will produce different degrees of wear, wear is more serious, produce more black iron powder, the oil black. Therefore, the greased hinge, depending on the use of oil and processing accuracy, or sooner or later there is transparent or black grease outflow, affecting the appearance to different degrees. Seven, often said door and window hardware, what exactly refers to the “five” gold? Building lock: a lock installed on the door and door frame of a building that needs to be opened and closed. It is generally composed of the lock body (including the lock tongue, door and window hardware, control mechanism and brake mechanism) and the lock panel, handle, cover plate and so on.  Handle: used to open and close metal window sashes. It is generally installed in the middle of the edge of the window sash, and some are also designed to be linked with the latch and door and window hardware.
