Corner codes are often used in decorative engineering and furniture assembly, as long as they need to be fixed at a 90 ° right angle, corner codes will be used. Corner codes make furniture installation more three-dimensional. In the production of doors and windows, corner codes are used as connectors for door sashes, window sashes, and outer frames. In terms of material, there are two types of door and window corner codes, namely plastic corner codes and aluminum corner codes.

The characteristics of plastic corner codes are lightweight and affordable. Plastic itself has a certain degree of resilience, which can provide a certain buffering effect when opening and closing doors and windows significantly. Even though plastic corner codes have excellent shock absorption and noise reduction functions, their drawbacks are more obvious. Plastic corner codes have poor heat resistance and can deform at slightly higher temperatures. They are prone to combustion, and even thermosetting resins can smoke and easily peel off at temperatures exceeding 200 degrees Celsius. So in the production and assembly of system doors and windows, plastic corner codes have gradually withdrawn from the mainstream stage.

The characteristics of aluminum corner codes are material stability, strong weather resistance, resistance to deformation, and long service life. In terms of waterproofing and sound insulation, aluminum alloy corner brackets are generally divided into three types; 1. Ordinary aluminum corner code, 2. Integral corner code, 3. Glued corner code. Each type of corner code has a different effect.

①. The activity corner code is composed of two aluminum pieces, connected by screws in the middle, and comes with a locator, making it easy and convenient to use. After binding with aluminum corner codes, improving the neatness of corner seams can extend the service life of doors and windows. The disadvantage is that over time, the sealing, sound insulation, and wind pressure resistance of the window may decrease.

②. Glue corner code

Glue injection corner code is a commonly used door and window corner code, which is made of cast aluminum injection molding and has improved overall strength and aesthetic appearance of corner joints. And there is a guide groove inside, which can be glued after assembly. The glue will fill the corner code through the guide groove to expand the two corner codes outward, making the assembly more compact. The sealing and waterproof properties have been enhanced.
