Let's take a look at what is the popularity of door and window hardware. Today we will share some simple methods to let us know how to identify inferior door and window hardware!

1、 Look at the profile surface quality

The surface of good door and window hardware profiles is smooth and textured, and the surface is sprayed with natural color treatment, giving a smooth feeling; the secondary door and window hardware is rough, and the color is not full. Door and window hardware is a general term for all kinds of metal and non-metal accessories installed on building doors and windows.

Next, look at the profile structure

Good window hardware contour geometric cutting, distortion, will not bend the contour, the correct angle, slice thickness enough, such as 60 kinds of door and window hardware, the contour thickness is 6cm, and the total weight, the proportion of less wear-resistant strip; time and window hardware, will be used to support the virtual contour 60, supporting the thickness of wearing items, aluminum material will be relatively small.

Third, look at the outline of the insulating strip

The domestic thermal insulation tape is mostly made of PVC plastic material, while the imported thermal insulation tape is polyamide, i.e. nylon thermal insulation tape and high-quality door and window hardware. Generally, the imported thermal insulation tape has good high and low temperature performance and low heat conduction value, which can achieve the effects of heat insulation, thermal insulation, environmental protection, environmental protection and energy saving.
