However, the steel pipes extending out of the wall need to be cut away at a later stage, resulting in holes in the wall that need to be manually sealed. If the sealing is not standardized or missed, the risk of wall leakage is increased, causing the wall to peel and mold in the later stage, seriously affecting the use function of the building and making it difficult to repair.
