Why do stairs also need to do electric penetration, designers to answer the question:

Stair is a corner area that is easy to be ignored, and this insignificant corner, we will remind customers to pay attention to moisture-proof problem, why?

Because stair is in the main function of the building is "connect".

Although the staircase itself may be raised or concrete, it faces a wall, and moisture from the wall is likely to spread to the staircase, affecting the degree of wetting and dryness on the surface of the staircase, resulting in moldy conditions on the staircase.

Stairs are the passageway for people to enter and exit. Once problems occur, it will affect customers' living experience. In order to achieve the best final effect, we suggest customers to do a good job of moisture-proof stairs.

It is basement stair not only, the stair of first floor needs to do likewise moistureproof.

Because the air temperature difference between the first floor and the second floor is large, cold and heat intersection is formed in the passage of the staircase. If electric penetration is not moisture-proof, it is easy to cause the wall condensation problem, causing damage to the staircase itself and adjacent wall.
