1. The load capacity of the platform's hot-dip galvanized steel grating should meet the designed safe load requirements:
For single-passenger steel gratings, the uniform load capacity shall not be less than 3.0 kN/m2;
For two-way steel gratings, the uniform load capacity shall not be less than 5.0kN/m2;
High-density pedestrian steel grating, its uniform load capacity is not less than 7.5kN/m2;
For steel gratings used on traffic roads, the wheel pressure is increased by 10%, and the uniform load capacity should be increased by 25% accordingly.
2. If there are cuts in the hot-dip galvanized steel grating of the platform, the remaining area of the steel grating should have the same load capacity.
3. The load requirements of the platform's hot-dip galvanized steel grating shall be proposed by the design department and the user, or the design department may select the specifications.
4. The calculation of the relationship between the load, span and deflection of the platform's hot-dip galvanized steel grating is carried out according to the principle of steel structure calculation. The relationship between safety load and span and deformation deflection of commonly used steel grating models.
