Door and window hardware is an important part of doors and windows, which determines the performance and life of doors and windows.
Door and window hardware is mainly used to open and close doors and windows. The quality of the hardware directly affects the performance and service life of doors and windows.
Therefore, when purchasing doors and windows, you must pay attention to hardware accessories. Some people think that hardware is just a small part, but in fact it can affect the performance of doors and windows and the life of the entire window.
01Hardware composition
The components of the flat-opening top-hanging hardware include handles, lock boxes, hinges, top-hanging transmission components, locking points, lock seats, etc. Exposed hinges are not recommended because they have poor sealing properties.
The hardware for the external opening includes handles, lock boxes, external opening hinges or connecting rods, lower suspension transmission components, locking points, lock seats, and the most important anti-fall rope. The hinge method is not recommended because it is unsafe.
02Hardware brand
Common domestic brands include: Kin Long, Hopewell, Guoqiang, Shenzhen Haobo, imported Noto, Weihagen, Stanford, etc.
Imported brands include German Noto, Silkilia, Gewu, Haobao, Fushibo, Sobinco, Gies, etc. Among them, Haobao and Fushibo only make hardware handles, and they still insist on overseas production and domestic sales. It is purely imported.
But the door and window hardware is not the best imported. China is a big manufacturing country. The precision and quality of many products are no worse than foreign ones, or even ahead of them. The same is true for door and window hardware. So how to distinguish the quality of door and window hardware?
1. Look at the load capacity
Taking the window sash size 700*1400 as an example, the aluminum weight is about 10KG, the three-layer 5mm insulating glass is about 28KG, and the total weight does not exceed 5OKG. With the brand just mentioned, load-bearing capacity is not a problem.
If it is an extra-large window sash, you can choose imported weighted hardware. Imported brands such as German Noto, Silkia, and Gewu all have hardware series with a load capacity of more than 150KG.
2. Look at the hardware material
The common main raw materials are zinc alloy and stainless steel. Parts such as handles and lock boxes are generally made of zinc alloy. The higher the grade of zinc alloy, the better the quality;Load-bearing parts are generally made of stainless steel, and the higher the grade, the better the quality.
3. Look at the surface treatment
There are three common treatment methods, namely powder spraying, fluorocarbon spraying, and anodizing. Among them, the anodizing method is the most delicate and is often used for handle surface treatment. It has a comfortable grip, smoothness, and resistance to bumps. Regular products are being introduced to the market. They will undergo rigorous salt spray testing before production to avoid patina and peeling.
4. Check the number of activations
The German IFT fatigue resistance test requires a standard counterweight to be turned on more than 60,000 times to be considered qualified. Domestic requirements are relatively low, and it is also based on a standard counterweight to be turned on more than 20,000 times to be considered qualified.
To sum up, when choosing door and window hardware accessories, you need to pay attention to many factors. Only by choosing the right hardware accessories can you ensure the use effect and safety performance of doors and windows.
When purchasing door and window hardware accessories, it is recommended to choose regular manufacturers, pay attention to product quality and performance, and consider various factors such as the use environment and needs of doors and windows, in order to choose more suitable hardware accessories.
