The external material of the flue (this can be coating, can be pasted on other materials, etc., per square meter) Of course, if there are meters inside and outside, only one material can be used.
Only one material, such as metal. It can also be calculated by area, square meters. Or the weight of the metal is charged.
At the entrance of the flue, there should be some range hoods and other devices, which will be expanded to facilitate smoking, and this place can add more materials and money.
Flue exit, this place will generally add a cover, rainproof, price blower, convenient smoke exhaust and the like, the amount of this material has gone up, and the price has also gone up.
The flue generally has a 90-degree corner, and the material of this corner will also increase, and the labor cost of installation may be a little higher.
That's all I can think of now, we can talk about Yu Xun together and learn together.
