Why can door and window hardware accessories affect the economic performance and the life of the entire window?
TECH ARTICLE NO. 21| Why can door and window hardware accessoriesaffect the economic performance and the life of the entire window?
There is also fierce market competition in the building industry and door&window industry. One of the important ways to break away from single price competition and create a healthy market environment is to continuously enrich product functions and expand product profit space with technical advantages. The important link that can enrich the functions of door and window products is window hardware accessories.
The quality of window hardware also has an impact on the life of doors and windows. Good hardware should appear thick, with a good surface gloss, a dense protective layer, and no scratches. The most important thing is that it should be flexible to open.
With the improvement of life and the development of modern technology, there are different materials for making window and door hardwares. Nowadays, in residential and other construction projects, there are generally materials such as polyvinyl chloride (PVC), aluminum alloy, stainless steel, and color steel. Window and door made of different materials also use different hardware fittings for windows and doors. The opening methods of doors and windows are push-pull, horizontal, and suspended. The hardware fittings used for doors and windows should also be consistent with them. Hardware accessories can be regarded as the heart of doors and windows. The full play of all the performance of doors and windows, such as wind pressure resistance, air tightness, water tightness, thermal insulation, thermal insulation, and sound insulation, is closely related to hardware accessories.
How wide of the window sash is the best fit for a casement window?
What are the disadvantages of installing oversized window sashes? Some owners like large window sashes and believe that this ventilation effect is good. In fact, the ventilation effect of larger and smaller window sashes is not significantly different. What are the drawbacks of window sashes? One is that the window sash is too heavy, which increases the load on sliding braces, hinges, and other accessories, increases friction, shortens the service life of the accessories, and also increases the resistance to opening and closing. The second is that when opening and closing the window sash, the stroke of the window casement handle lock increases, requiring more arm extension, which can also increase the difficulty of opening and closing and increase the risk. Generally, a window sash width of 60-65cm is appropriate.
During the use of top hung casement window, poor quality widnow friction hinges (window friction stay) can become loose after a period of use, which can seriously cause the window sash to fall off and create safety hazards. Therefore, many people will want to know, what are the material requirements for high-quality top hung and casement window friction hinges?
The window friction hinge must be protected against rust, as rust can affect the smoothness of sliding, reduce the mechanical properties of the window friction hinges, and lead to fracture. To have good corrosion resistance, it is necessary to select stainless steel materials of high grade 300 series or above, such as 304 stainless steel. This type of stainless steel has high corrosion resistance, strength, and toughness. However, low grade stainless steel with 2 characters, such as 201 and 202, is lower in price but has lower corrosion resistance than 300 series. And 304 stainless steel has high wear resistance. In addition, the thickness of the friction hinges also affects the bearing capacity. When the window sash is heavy, it is best to choose a sliding brace with a thickness of more than 2.5mm.
At the same time, many people also reflect on window and door hardware of uising aluminium alloy window hinges. Why does the window hinge expose grease after a period of time?
In fact, after a period of operation of the aluminium alloy window hinge, the viscosity of the grease added inside decreases, making it easier to flow out; At the same time, the shaft core and reel of the window hinge will suffer from varying degrees of wear. When the wear is severe, more black iron powder will be generated, which will blacken the grease. Therefore, depending on the oil used and the processing accuracy of the greased hinge, there may be transparent or black grease flowing out sooner or later, which affects the appearance to varying degrees.
