They are not only waterproof but also fireproof, and during the installation process It is convenient and easy to remove, the material is pure steel plate, and the quality is of the highest quality. Under normal circumstances, we will install waterproof closed doors in the passages of water pump rooms and substations to prevent sudden intrusion. The size confirmation of waterproof closed doors is actually very simple. There are four most commonly used national standard specifications:
Model & Drawing Number & Weight
B.*.&
B.*.&
B.*.&
B.*.&
After we know the above four national standard waterproof doors, it is not difficult to infer the size based on which we determine the mine waterproof and airtight doors. The size of the door is determined by the size of the water pump room door, and the size is the internal size, not the external size. We must pay special attention to this when shipping. It is easy to install and is a representative product of mine waterproof closed doors.
