Technical Data Sheet
IFR - Isophtalic Fire Resistant
IFR 30/19x19/7x5 - Concave
In accordance with the standards: EN ISO 14122-2: 2016 and DIN 24537-3, the following is adopted:
The minimum loads to be considered for walkways and working platforms are as follows:
- 2.0 kN / m2 with a uniform load on the structure;
- 1.5 kN with a concentrated load applied in the most unfavorable place
on a floor area of 200 mm x 200 mm.
The deflection of the floor surface after applying the load assumed in the design should not be greater than
1/200 of the span of the supports.
The difference in height between the loaded floor surface and the adjacent unloaded floor surface should not
exceed 4 mm.
If the deflection is 1/200> 4mm, it is recommended to use a connector.
According to BGI / GUV-I 588-1, the minimum support of the grating should be equal to the height of the grating,
but not less than 30 mm
