In the national fire-rated door regulations, there is no hard and fast rule, and most of them are handled according to the requirements of the construction site. If the size of the fire-rated door is large, for the safety of the fire-rated door in use, Bast Intelligence Equipment generally recommends customers to do pre-embedding or grouting treatment. The door size of the fire-rated door is too small, so it is not necessary to do it.
In addition, if the tiles are already affixed to the ground, it is difficult to cut when embedding, and the embedding process may not be performed at this time.
There are many fire-rated door manufacturers on the market, and the products on the market are also mixed. If you need to buy a fire-rated door, you must see whether the fire-rated door manufacturer has the fire-rated door production qualification. Different brands of fire-rated doors use completely different manufacturing processes and materials. Although they all have fire protection capabilities, there is a big gap in details, workmanship, durability, and environmental protection. The installation of fire-rated doors must also be carried out by professional skilled workers.
