Weight calculation formula of hot-dip galvanized steel grating

Weight calculation formula for hot-dip galvanized steel grating:

A. The most traditional method is: you can distinguish the weight of the steel grid, the weight of the crossbar, the weight of the steel grid, the weight of the steel grid, the weight of the surface treatment of the steel grid, and then add all of them. stand up.

B. Calculate the theoretical weight of steel grating: For steel gratings with a length of less than 1 meter (such as trench cover) or steel gratings that require special edges, the weight will increase due to the increase of the side panels. When flat steel packaging is used and the length of the steel grating is not less than 1 meter, the theoretical weight of the steel grating is calculated according to the following formula: Wt=(b1t1N1+b2t2N2+2b3t3)ρ×10-6

Steel grating weight, unit: kg/m2 (kg/m2); t1 load-bearing flat steel width, unit: millimeters (mm); b1 load-bearing flat steel thickness, in millimeters (mm); N1/meter load-bearing steel grating Number of flat steel bars; t2 width of cross bars, in millimeters (mm); b2 thickness of cross bars, in millimeters (mm); N2: number of steel bars per meter of steel grating; width of flat bars on t3 side, in millimeters (mm); b3——thickness of side flat steel, in millimeters (mm); ρ-material density, in kilograms/cubic meter (kg/m3); steel density is calculated at 7850kg/m3; µ---surface treatment weight gain coefficient ; The weight gain of hot-dip galvanizing is calculated as 1.06.

As a high-cost structural form, hot-dip galvanized steel grating has been widely used in newly-built old roadbeds covering waterways and roads. The surface of the hot-dip galvanized steel grille adopts a special hot-dip galvanizing treatment, and its chemical and physical properties are stable, and it is not easy to be corroded and oxidized by air and microorganisms. Can significantly improve the carrying capacity of the channel. Prevent collapse. The galvanized steel grating has a steel spacing of 3cm, which has a large impact resistance and has the characteristics of the largest span. The longer the service life, generally between 40-50 years.
