  • Detail

Knowing more about door and window accessories will help you buy high-quality doors and windows. Now let's follow yuetongchuang Xiaobian to learn about the purchase of door and window accessories

as we all know, the manufacturing materials of doors and windows are divided into several kinds, including aluminum alloy, stainless steel, color steel, etc. the hardware accessories of different materials will be different, but some businesses do not strictly follow the standards. Knowing more about door and window accessories will help you buy high-quality doors and windows. Now let's follow yuetongchuang Xiaobian to learn about the purchase of door and window accessories

type of door and window accessories

1. Handle: used for casement windows

the main function is to compress the casement on the window frame when the casement is closed, so as to achieve the sealing effect

when shopping, you should pay attention to observe that the surface is flat, free of burrs, with a sense of weight in your hand, and the coating surface is uniform

2. Hinge: used for casement doors and windows

when purchasing, you can observe the hinge materials, including copper, iron plated copper, stainless steel, aluminum alloy extruded materials, etc. do not choose zinc alloy cast hinges

3. Sliding brace: a device that supports the casement to realize opening, closing and positioning

it is better to choose stainless steel material when purchasing, and the surface should not have defects such as scratches, sharp edges, burrs, etc. when the sliding support is opened and closed, there should be a little resistance

4. Pulley: bear the weight of each sliding door and window and move horizontally

when purchasing, attention should be paid to the material of the pulley frame and whether the pulley adopts needle bearing or ball bearing. For the pulley used for sliding door, heavy-duty door pulley should be selected, and the pulley used for sliding window must not be replaced

5. Half moon lock: most of them are hook locks between fans

it is better to choose stainless steel or aluminum alloy

6. Hinge: trigeminal hinge with high strength, strong bearing capacity, convenient disassembly and assembly, flexible opening and closing, silencing and other characteristics is preferred

7. Sealing strip: due to the combination of door and door panel, the noise at the moment of closing the door is as high as 120 dB, which seriously affects physical and mental health

high strength sealing strip is adopted, which does not react with the paint and ensures the smoothness of the contact paint surface. And it also has the characteristics of shock absorption, silencing, sealing, sound insulation, moisture-proof and so on

hardware purchase tips

1. Hinges, slides and locks with good sealing performance should be selected. When shopping, open and close, pull several times to feel its flexibility and convenience

2. Locks with good flexibility should be selected. When purchasing, you can insert and dial the key several times to see whether it is smooth and whether the switch can be screwed up to save effort

3. Choose decorative hardware with good appearance and performance. When shopping, it mainly depends on whether the appearance is defective, how the electroplating gloss is, and whether the material feeling is smooth

(1) doors and windows and accessories: they must meet the design requirements, and the specification and model should meet the national standards

(2) floor spring: the floor spring of the door should be stainless steel or copper. After installation, the opening and closing speed should be adjusted to facilitate use. The hydraulic part shall not leak oil. Door stopper can also be used

(3) door lock: it should be a double-sided safety lock

(4) push hand: stainless steel, aluminum alloy or copper

(5) pulley and pulley frame: the pulley can be hard nylon pulley and pulley frame, which are generally galvanized steel products

(6) sealing material: sealing rubber strips should be used together with waterproof sealant

maintenance method of door and window accessories

1. Stainless steel handles and other stainless steel "hardware" can be scrubbed with brightener to increase brightness

2. Hinges, lifting wheels, casters and other moving parts may reduce their function due to the adhesion of dust during long-term movement. Fiddling with one or two drops of lubricating oil every six months can keep them smooth

3. Pay special attention to the rotation and stretching direction of the handle, and avoid using dead force. In particular, children should be taught not to hang and sway on the door handle, which is prone to danger and may be harmful to the inner door

4. When the lock cylinder cannot rotate sensitively, scrape a small amount of black powder from the pencil lead and gently blow it into the lock hole. This is because the graphite component is an excellent solid lubricant. Do not drop lubricating oil, because it will be easier to adhere to dust

with the continuous progress of the times, sustainable development has been deeply rooted in the hearts of the people. The development of building energy conservation, especially the selection and utilization of energy-saving door and window hardware accessories, is bound to become the focus of candidates. If the domestic door and window industry wants to take the lead in the development of building energy conservation, it must meet the needs of the market, increase the quality of energy-saving door and window products, and at the same time, it must be innovative, constantly adopt new technologies, new materials and new processes, avoid deliberately pursuing differentiation and personalization, and strive to achieve the integration of saving enterprise production costs and energy-saving doors and windows and building energy conservation, so as to promote the sustainable progress of building energy conservation
