　　YXB48-200-600 floor deck can eliminate the fireproof coating at the bottom of the board, can completely replace the lower steel bar, and can reduce the thickness of the floor slab and save the amount of concrete. The unique suspension system of the closed floor deck can also save the cost of mechanical and electrical pipe installation. In addition, due to the above advantages, the processing speed can be significantly accelerated and the construction period can be shortened. Therefore, the use of closed-end floor decks can reduce the direct cost of the project on the one hand, and reduce the project management cost on the other hand.
