1. We consulted most of our customers about the level of fire doors. In general, the drawing will show the height of the fire door. The fire door is divided into three grades: A, B and C, indicating the fire integrity of the fire door, i.e. fire resistance time. At present, China's standard is that the fire resistance time of class A is not less than 1.5 hours, that of class B is not less than 1.0 hours, and that of class C is not less than 0.5 hours. Class A is usually used in more important places, such as KTV compartment door, power distribution room and computer room. Class B is usually used for corridors and other places, while class C is usually used for pipeline wells.

2 .防火門材料:所用防火門的等級將在一般建筑圖紙上標出，但所用材料不會在圖紙上標出，所以很多用戶會問是否有幾扇防火門？它們都是標準的嗎？等等。防火門通常分為鋼木門和鋼防火門，無論是鋼木門還是鋼防火門，它們分為三個等級: a、b和c。一般來說，安裝在建筑物上的防火門并沒有規(guī)定使用什么材料。然而，我們在實踐中的做法是，鋼防火門通常在室內(nèi)和室外使用，因為它們在打開和關(guān)閉時相對安靜，鋼防火門不會相互碰撞，除了防火之外，鋼防火門還可以起到更好的防盜和防損壞作用。

2. Fire door materials: the grade of fire doors used will be marked on the general architectural drawings, but the materials used will not be marked on the drawings, so many users will ask whether there are several fire doors? Are they all standard? wait. Fire doors are usually divided into steel wood doors and steel fire doors. Whether steel wood doors or steel fire doors, they are divided into three grades: A, B and C. Generally speaking, fire doors installed on buildings do not specify what materials to use. However, our practice in practice is that steel fire doors are usually used indoors and outdoors, because they are relatively quiet when opening and closing, and steel fire doors will not collide with each other. In addition to fire prevention, steel fire doors can also play a better role in anti-theft and damage prevention.

3 .防火門的樣式和這里要打開的樣式主要是指門的形狀，如單門、雙門、母門等。在實踐中，我們認為寬度為1米的防火門可以做成單扇門，寬度為1.2米的防火門可以做成雙扇門或母門形狀。如果門的一面被建筑物擋住，另一面是敞開的，但是因為門太寬而無法打開，它會影響入口和出口以及美觀，母親門會被做成母子形狀，一邊大一邊小，通常比例是3 / 7。防火門的開啟方向主要是指單扇門是向左還是向右開啟。我們的一般識別方法是人們站在門外，這意味著所有防火門都向外打開，不允許向里面打開。防火門的開啟方向必須與疏散通道的方向相反。因此，向外開門的人站在門外，看著門對面的鉸鏈。如果鉸鏈在左邊，它在右邊被稱為右邊，兩邊的尺寸也由母門決定。

3. The style of fire door and the style to be opened here mainly refer to the shape of the door, such as single door, double door, mother door, etc. In practice, we believe that a fire door with a width of 1m can be made into a single door, and a fire door with a width of 1.2m can be made into a double door or a mother door. If one side of the door is blocked by the building and the other side is open, but the door cannot be opened because it is too wide, it will affect the entrance, exit and beauty. The mother door will be made into a mother child shape, with one side large and the other small, usually with a ratio of 3 / 7. The opening direction of the fire door mainly refers to whether the single door is opened to the left or right. Our general identification method is that people are standing outside the door, which means that all fire doors are opened outward and are not allowed to open inward. The opening direction of the fire door must be opposite to that of the evacuation passage. So the person who opened the door stood outside the door and looked at the hinge opposite the door. If the hinge is on the left, it is called the right on the right, and the size of both sides is also determined by the mother door.

4 .訂購防火門尺寸和洞口防火門尺寸:一般來說，有兩種涂漆和未涂漆的。我們稱之為凈尺寸。通常，沒有必要扣除它們。未刷漆的意味著可以在沒有水泥找平的情況下看到門洞內(nèi)的磚塊。這種門開口需要扣除寬度和高度，通常寬度為20毫米，高度為10毫米。如果你需要鋪設(shè)地磚，你還需要扣除地磚的尺寸，你還需要強調(diào)是放下框架還是嵌入它們。

4. Order fire door size and opening fire door size: Generally speaking, there are two kinds of painted and unpainted. We call it net size. Usually, it is not necessary to deduct them. Unpainted means that the bricks in the door opening can be seen without cement leveling. The width and height of this door opening need to be deducted. Usually, the width is 20mm and the height is 10mm. If you need to lay floor tiles, you also need to deduct the size of floor tiles, and you also need to emphasize whether to put down the frame or embed them.

5、防火門門扇是否加防火玻璃，能增加照明效果。

5. Whether the fireproof glass is added to the door leaf of the fireproof door can increase the lighting effect.
