【 Building materials network 】Profile and Glass Occupied doors and windows Most of the area, but it determines the door window The important factor of whether it can be used for a long time is not only the profile, but also the Door and window hardware Itself.

1、 The quality of hardware directly affects the service life of doors and windows

A good door and window can not be separated from a complete set of hardware accessories, such as hinges, handles, connecting rods, wind braces pulley 、 Latch 、 Door closer And other hardware accessories systematically support various functions of doors and windows.

The impact of door and window hardware on the service life of doors and windows is that when the hardware accessories supporting the normal operation of doors and windows are damaged, broken, rusted and aged due to improper use or too long use, the actual functions of doors and windows will be greatly weakened, and their potential safety hazards will follow. At this time, we need to repair, maintain or replace them. Generally speaking, the service life of hardware that is normally used or well maintained can be maintained at about 10 years. Therefore, it is very important to select the hardware for doors and windows, and daily maintenance is also essential.

2、 How to select hardware fittings with good quality and performance?

(1) When selecting hardware accessories, try to choose products with brand and guaranteed quality. The quality level of hardware fittings shall be consistent with that of doors and windows: the structure and shape of hardware fittings shall be consistent with that of profiles, and the color shall be coordinated and beautiful, the function shall be correct, the operation shall be flexible, and the installation shall be convenient.

(2) Hardware fittings shall be installed in complete, standard, reliable and accurate positions. After installation, doors and windows shall be beautiful in appearance, flexible and convenient in opening, and free from deformation, obstruction, collision, etc.

(3) Stainless steel products shall be preferred for exposed fasteners of hardware fittings.

(4) Side hung doors and windows and large size Sliding door Multiple locking points shall be adopted when the window is closed, otherwise the air tightness will be greatly reduced under the effect of negative pressure difference; Considering the convenience of operation, it is better to use multi lock point handle or driver.

3、 The daily maintenance of door and window hardware should be in the "right" position

1. Daily frequent inspection: the hardware connection fittings of doors and windows will be worn to varying degrees in daily use, and it is easier to oxidize and rust when exposed to moisture (in rainy days). So we should always pay attention Door and window accessories Once the accessories are found damaged, they should be replaced in time to ensure their safety.

Here, Suifu doors and windows should emphasize three places. The load-bearing parts such as door and window hinges and sliding braces also have anti falling ropes for outward windows. The hardware in these parts is an important link to ensure the safety of doors and windows. As long as we can keep abreast of their use in life, we can effectively avoid the risk of door leaf falling.

2. Screws should be tightened: if the hinge, handle, anti falling rope system and other hardware accessories are loose, they should be tightened in time to avoid hidden dangers. If the door lock does not open properly, add proper amount of lubricant to the key hole for lubrication.

Take the handle as an example. When the door and window handle is loose, find the position of the fixing screw, and use tools to tighten the loose screw; If the length of the screw is not enough, replace the long screw.

3. Don't forget to apply oil: applying oil for lubrication can make the door and window hardware smoother and reduce the wear of hardware. But it should be noted that this oil is not the same oil: we can choose automobile lubricating oil (peanut oil, engine oil, etc. are not recommended, which are easy to stick to dust). Use a brush to apply it on the sliding support, hinge, and the parts with friction and contact with hardware（ Hinge , lock point lock seat, etc.

4. Pay attention to corrosion prevention: under the humid coastal salt fog environment, the surfaces of doors, windows and hardware fittings are easy to be corroded. Aluminium alloy door The window is corroded by coastal salt spray, which affects both the overall beauty and the performance of doors and windows. Therefore, we should give priority to aluminum alloy profiles when purchasing aluminum alloy doors and windows surface treatment Process (such as fluorocarbon spraying and powder spraying).

Attention shall also be paid when selecting: the surface color of aluminum alloy doors and windows shall not have obvious color difference or different shades at the edges, bottom and surface joints. The color of the same aluminum alloy profile shall be uniform. If the color difference is obvious, it should not be purchased. In addition, the hardware fittings of doors and windows (hinges, handles, hinges, etc.) should be made of stainless steel as far as possible, and should be kept dry and free of water drops in daily use (frequent use of hands, frequent cleaning and frequent wiping), so as to effectively avoid salt spray corrosion day after day.

Sound insulation, let people experience; Safe and reassuring; Commitment gives people confidence! Behind every door and window is the persistence and persistence of our Suifu door and window craftsmen, which is also the interpretation of quality life. Choose doors and windows, choose safety and choose brands: With careful door and window brands, Suifu doors and windows will naturally give you peace of mind in choosing, buying and using.
