钢结构以其特有的优势,在工业与公共建筑中被广泛应用。焊接、安装及涂层防腐是钢结构施工的三大工艺,但在施工过程中,人们往往很关注钢结构的焊接与安装质量,对涂层防腐并未引起足够的重视,涂层防腐质量的好坏直接影响到钢结构的使用寿命,甚至影响到其使用功能。我们在对某加工厂进行钢结构构件巡查时,发现部分吊车梁出现较多细小的 Steel structure with its unique advantages, widely used in industry and public buildings. However, during the construction process, people often pay close attention to the quality of welding and installation of steel structures, and have not paid sufficient attention to the anticorrosiveness of the coating. The anticorrosive quality of the coating Good or bad directly affect the service life of steel, and even affect the use of its function. When we inspect a steel structure component of a processing plant, we find that some of the crane girders have more small
