Material: aluminum alloy is a commonly used profile for KFC doors, but the quality of aluminum alloy is good or bad. The better wall thickness is about 3mm, and the resistance and firmness are better. The relatively poor wall thickness may be 1.3mm- 1.5mm, with poor resistance and unreliability.
Door accessories: Accessories (door closer, door shaft, handle, bolt and lock) play an important role in KFC doors, and materials must not be chosen at will. Although the accessories are small, they are also an important factor affecting the price, and of course they can also affect the service life of a door. Take the door closer as an example. If it is imported, it can be opened for 6.5438+0 million times, and the natural price will be more expensive.
Production technology: the high-quality KFC door joint adopts high-frequency argon arc welding aluminum welding and high-strength special fasteners to ensure that the door body is firm and durable, and does not sag or deform.
Appearance: Ensure the appearance of KFC door, and the surface treatment technology of the door is better. The surface of the good profile adopts Japanese Hani electrophoretic paint, SANER coloring electrophoresis process and Swiss fluorocarbon spraying process to ensure that it will not fade for 50 years.
Generally speaking, Jiangsu Cardang has done a good job. You can shop around KFC and find the one you are most satisfied with.
