The inner white metal part is a small door cover, and the outer decorative Roman thread is a door cover;
2. The playing time is different
The small door cover is a traditional elevator door cover, which is installed to cover the gap between the elevator car and the external wall and beautify the elevator machine room. It is also made of stainless steel.
Elevator door cover is a new type of elevator decorative door cover. This door cover is made of various materials, not only stainless steel, but also some materials similar to stone. Including zinc-steel integrated door covers, nano-stone plastic door covers and so on.
On the one hand, the door cover can decorate the elevator, on the other hand, it can make up for the problems left over from the civil engineering process; For example, the distance between the wall and the elevator door frame is large, so it needs to be decorated with door covers.
Extended data:
Service conditions of elevator door cover:
1. Impact strength: GB7588-2003 requires that the elevator car door should be within 5cm*5cm, the static force should be 300N, and the impact force should be 1000N (approximately equal to the force that normal adults can exert), so it should have the same impact resistance as the elevator door cover to prevent lifting heavy objects, electric cars and bicycles from entering and leaving.
2. Waterproof and flame retardant: elevators are special equipment and are not allowed to be used in case of fire. However, as an important part of the stairwell, the elevator door cover must meet the corresponding flame retardant requirements (above V0) to improve the overall fire rating; Similarly, in a humid environment or in the case of being soaked, it is necessary to soak in water for 24 hours without deformation or cracking, so as to enhance the safety of the whole environment.
3. Safety: As a crowded place, safety is the most important thing in public places. The elevator door cover must be broken and damaged after being hit by destructive force without potential safety hazard, or even never fall off without endangering or damaging life and property (such news is increasing day by day).
4. Service life: As a public facility, the elevator has a lot of people/goods coming in and out every day, which will cause great damage and friction to the elevator door cover. The material of elevator door cover needs to meet higher standards to improve its service life. The service life of the elevator shall not be less than 16 years. As a part of it, the door cover should be used with the elevator as much as possible.
5. Environmental protection: elevator door covers are small in area, but large in quantity. In the modern society with the theme of environmental protection, we must call for the application of environmental protection materials in many aspects. Contribute to the green of the motherland and the world.
6. Simple working procedure: With the increasing labor cost, a variety of products such as buildings, furniture, elevator door covers have emerged, which not only saves working hours and labor costs, but also reduces working procedures accordingly, thus achieving high-efficiency and energy-saving work efficiency and meeting the requirements of modern society.
