According to the as-built drawings,

According to the as-built drawings, the flange of the column of the attached photos is 300mm wide, and 12mm thick. As showed in the photos, the flange of the column is 310mm wide and 45mm thick, including the thickness of the fire-retardant coatings. So it can be reckoned that the thickness of fire-retardant coatings at the flange end are 5mm, and those ones at the side face are 16mm. The thickness of fire-retardant coatings of the flange are different. Therefore the fire resistant material may be thinner than is required. According to the as built drawings, the fire resistance rating of column in warehouse is 2 hours. Refer to the code for fire protection design of buildings (GB 50016-2014), page 426, the thickness of fire-retardant coatings is 30mm.

根据竣工图纸，法兰的列的所附的照片是 300 毫米宽，12 毫米厚。如照片所示，列的法兰是 310 毫米宽 45 毫米厚，包括防火涂料的厚度。所以，它可以是估计在法兰的防火阻燃涂层厚度的结束是 5 毫米，和那些在侧脸是 16 毫米。法兰的防火涂料的厚度是不同的。因此防火材料可能比所需更薄。根据竣工图纸，列在仓库的耐火等级是 2 个小时。引用代码为保护建筑消防设计中 (GB 50016-2014 年)，页 426、 防火涂料的厚度为 30 mm。

根据竣工图纸，对附照片列法兰300mm宽，和12mm厚。在照片中显示，该列的法兰310mm宽45mm厚，包括对防火涂料的厚度。因此可以认为，在法兰端防火涂料的厚度为5mm，和侧面的那些是16mm。对法兰防火涂料厚度有差异。因此耐火材料可能比所需的薄。根据建筑图纸，仓库的防火等级为2小时。参照建筑设计防火规范>>（GB 50016-2014），426页，防火涂料的厚度为30mm。
