Calculation method:
The load-bearing capacity values for the bending load (primarily static load) are calculated according to the theory of elasticity,
taking their own weight into account. To name but a couple of examples, these calculations use the material and cross-section constants. When
calculating the load-bearing capacity values, the permissible steel stress of 160 N/mm² and the maximum deflection of L/150 are not exceeded.
The deflection indicated must be assessed for visual acceptability on a case-by-case basis!
Load:
If several different individual loads in variable distances affect a single-span beam (crossbar),
they can be added and considered an estimated individual load positioned centrally.
For enhanced safety, it is advisable to use U-shaped brackets!
In case of high loads, “push-through installation” is recommended!
Mounting on the ceiling and the wall:
The necessary fixing elements (screws and dowels) must be calculated
individually and must be suitable for the load with mounting rails!
