The zinc adhesion of galvanized H-beam steel should not be less than 610g / m2, the average thickness of zinc layer should not be less than 86um, and the thickness of local zinc layer should not be less than 80um. Detection method: first of all, take the two ends and the middle of the three parts to see whether the appearance is qualified. For the general new rectangle with an area of one square centimeter, the rectangle on the surface is basically the measuring surface, and the measurement between each basic measuring surface needs five points, and the arithmetic mean value should be taken as the local main thickness.
The storage site of galvanized H-section steel should be flat, and there should be no ponding. For steel structure engineering, galvanized H-section steel should be stored in different areas according to the type and model. The bottom cushion of galvanized H-beam should have enough supporting surface, which can prevent the fulcrum from sinking and the inclined laying of chassis, and the interlayer should be placed in a reversed direction When stacking the same galvanized H-beam, the fulcrum in each layer of galvanized H-beam should be on the same vertical line, and stacking should not exceed 5 layers, and cushion should be set between layers, so as to prevent the phenomenon of crushing or deformation of galvanized H-beam.
