In the "room" of doors and windows, hardware accessories are the heart of doors and windows, and are the key to supporting the performance of doors and windows. A good door and window is inseparable from a complete set of hardware accessories, hinges, handles, connecting rods, wind bracing, pulleys, latches, door closers and other hardware costs can account for 15%-30% of the overall cost of doors and windows, or even more... Do you still think that door and window hardware is a supporting role or irrelevant?
First, the quality of hardware directly affects the life of doors and windows
In fact, the important factor that determines the long life of doors and windows is not only the profile, but also the door and window hardware itself. Any doors and windows have a certain service life; The longer the use time (wind and rain, sun and rain, daily opening and closing loss, etc.), the more serious the wear and age of the doors and windows themselves. The impact of door and window hardware on the service life of doors and windows is: when the hardware accessories that support the normal operation of doors and windows are damaged, broken, rusted and aged due to improper use or too long use, the actual function of doors and windows will be greatly weakened, and their safety hazards will follow. At this time, we need to repair it or replace it. Generally speaking, the service life of hardware with good normal use or maintenance can be maintained for about 10 years.
Second, door and window hardware accessories are directly linked to the performance of doors and windows
The comprehensive performance of doors and windows is closely related to the structural types of door and window hardware. For example, the load-bearing accessories of casement windows include hinges, hinges (sliding braces), etc., which are used to ensure the normal opening of casement windows, so that the sash is stable and does not fall off in daily opening or windy weather, and improves the wind pressure resistance and stability of the whole window.
For example, the locking parts of doors and windows mainly include lock points, locks, actuators, cornerers, etc. With the sealing system of doors and windows, the use of these hardware will have an important impact on the overall performance of doors and windows (burglar resistance, sealing, sound insulation, thermal insulation performance, etc.). In addition, door and window handles and linkages can also realize various opening functions by changing the position of the handle handles.
Third, door and window hardware and door and window energy-saving effect are closely related
Improving the energy-saving effect of doors and windows focuses on improving the overall sealing performance of doors and windows, and improving the sealing performance of doors and windows needs to rely on the sealing strip and the door/window sash to press the sealing strip to achieve (this tight pressure comes from the hardware).
The lock hardware that has an impact on the sealing performance of doors and windows can be roughly divided into two categories: multi-lock point hardware and single-lock point hardware.
The lock points and lock seats of multi-lock hardware are distributed around the doors and windows, when the doors and windows are locked, the lock points and locks are firmly buckled together, and the hinge or sliding brace cooperates to produce a sealing pressing force to form enough seals between the fan and the frame. Therefore, the use of multi-lock point hardware can improve the sealing and anti-theft performance of doors and windows (while the sealing and theft resistance brought by single-lock point hardware will be relatively poor).
Fourth, the purchase/selection of door and window hardware accessories
- Save money and don't think about saving door and window hardware accessories
If the quality of hardware accessories is not good, (after the doors and windows are locked) the lock points and lock seats cannot be tightly buckled together, and the sealing pressing force cannot be generated, then the overall tightness of the doors and windows will be reduced. Moreover, the hardware with unqualified quality is easy to age and damage, and the final impact is the safety of doors and windows.
When choosing hardware accessories, Suifu doors and windows recommend choosing products with guaranteed quality and high brand awareness. 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 exposed fasteners of hardware accessories should give priority to stainless steel products (taking the sliding brace as an example, if the sliding brace wants good rust resistance, it is best to use stainless steel materials above the high grade 300 series, such as No. 304 stainless steel. In addition, the thickness of the sliding brace also affects the bearing capacity, and it is best to use the sliding brace with a thickness of more than 2.5 when the sash is heavier. ）
- Hardware accessories should be reasonably designed and installed
Many inexperienced whites often ignore the rationality of hardware selection when designing doors and windows. For example, the design of the inner opening and inverted window does not consider the thickness of the inner wall window sill and is installed against the wall, resulting in the window cover or tile being pasted to the inner opening and inverted window hinge, affecting the normal use of the window; The sliding window was not equipped with a bumper block, causing the hook lock to be broken by the window frame...
When installing aluminum doors and windows, be sure to find experienced measurement designers and installation masters. Hardware accessories should be installed, standardized, reliable and accurate position. After installation, the doors and windows have beautiful appearance, flexible and convenient opening, and must not be deformed, hindered and collided.
- Non-perishable and oxidation resistance is the focus of hardware selection and application
It is said that aluminum alloy doors and windows are easy to oxidize and corrode in unfavorable climatic environments and coastal areas, and the surface color of aluminum alloy doors and windows should not have obvious color differences or different shades of coloring at the edge, bottom and surface connection. The color of the same aluminum alloy profile should be uniform and consistent, if the color difference is obvious, it is not suitable for purchase. As for the key links of doors and windows, hardware accessories should show stronger corrosion resistance. Door and window hardware accessories (hinges, handles, hinges, etc.) are made of 304 (or three-figure) stainless steel as much as possible, and should be kept dry and water-free in daily use, so as to effectively avoid salt spray corrosion day after day.
