The treatment of galvanized H-shaped steel in steel structure engineering should have technical requirements, and the galvanized quality of H-shaped steel should meet the technical requirements of the design, and there are the following requirements:
(1) The amount of zinc adhesion of steel structure engineering for galvanized H-shaped steel:
The zinc attachment amount of galvanized H-shaped steel can not be less than 610g/m2, and the average thickness of the zinc layer can not be less than 86um, and the thickness of the local zinc layer is not less than 80um. Detection method: First of all, take the two ends and the middle of the three places to see the appearance of the qualified, for the general new area is a square centimeter rectangle, the rectangle on the surface is basically the measurement surface, and the measurement between each of the basic measurement surface is required five points, to take the arithmetic average of which as the local main thickness.
(4) Galvanized H-shaped steel in steel structure engineering requirements for storage:
The storage site of galvanized H-shaped steel should be flat, and there is no water. For galvanized H-shaped steel in steel structure engineering, it should be stored according to the type and model of the partition, and the bottom pad of galvanized H-shaped steel should have enough support surface, which can prevent the subsidence of the fulcrum and the slant of the chassis. And when stacking the same galvanized H-shaped steel model, the fulcrum in each layer of galvanized H-shaped steel should be on the same vertical line, and the stacking can not exceed 5 layers, and the cushion layer should be set between the layers, so as to prevent the occurrence of galvanized H-shaped steel crush or deformation.
