Таблиця навантажень для пресованого решіткового настилу з відстанню між несучими смугами 33,33 мм
— range recommended by the manufacturer. In this range, the deflection arrow does not exceed 1/200 of the distance between the supports and is always less than 4 mm. The data are for the effect of a point single load of 150 kg on a 200x200 mm contact spot anywhere in the grid.
— range in which the deflection arrow does not exceed 1/200 of the distance between the supports under the influence of a point single load of 150 kg on the contact spot 200x200 mm anywhere in the lattice

Since this load table is designed for gratings with a distance between the bearing strips of 33.3 mm, to calculate the load of the floor with other parameters, use the following table, which presents the conversion factors:
For example, it is necessary to calculate the maximum distributed load Fv for decking KOP 30x3 / 44x33 / 800x1000.
According to the table of loads, the value of Fv for such flooring with a cell 33.33 mm is 2430 kg / m2. - 1.5.
The coefficient for a 44 mm cell is 0.74.
Thus, the required value is 2430 * 0.74 = 1798 kg / m2.
