Obviously, it goes without saying the importance of doors and windows to families. Door and window hardware refers to various metal and non-metal accessories installed on building doors and windows. Assists in opening and closing doors and windows. This surface is usually electroplated or coated, sturdy, durable, flexible, economical, and aesthetically pleasing. Door and window hardware can be divided into building door locks, handles, supports, hinges, door closers, handles, latches, window hooks, anti-theft chains, and sensing door opening and closing devices according to their uses. Most modern home decoration hardware requires a range of products from the market. What if the doors and windows make you scratch your eyes? belowDoor and window accessory manufacturersI will tell you how to judge the quality of door and window hardware.


1、 Look at the price

Generally speaking, due to high production costs, the price of high-quality door and window hardware is about 30% higher than that of low-quality door and window hardware. The tensile strength and yield strength of some door and window hardware with aluminum profiles and wall thickness of 0.6-0.8mm are far lower than relevant standards, and their use is not safe. In addition, many self-employed individuals are engaged in the processing of door and window hardware, and they do not understand the structural characteristics and performance of door and window hardware. In order to reduce work and material costs, inferior products should not be used. A better choice for ordinary door and window hardware manufacturers.


2、 Look at the processing

The hardware of doors and windows is of high quality, finely processed, specially installed, with good sealing performance and convenient switching. Poor quality door and window hardware, aluminum profile series and specifications are blindly selected, rough processing is not differentiated, mechanical processing is replaced by sawing, installation is not required, sealing performance is poor, and the switch is not qualified, which is not easy. There are not only air leaks and glass breakage, but also sliding parts or glass are prone to scratches or touching when encountering strong winds and external forces, resulting in personal injury.


3、 Look at the materials

The thickness, strength, and oxide film used for high-quality aluminum door and window hardware should meet or exceed relevant standards. It should have a wall thickness greater than 1.2 millimeters, with a tensile strength of 157 Newtons per square millimeter and a yield strength of 108 Newtons per square millimeter. The thickness of the oxide film should reach 10 microns. If the above standards are not met, the quality of door and window accessories will be poor and cannot be used.
