SiSo - extremely high pull-out tension values and superior structural integrity

The extreme rigidity is generated by a membrane
penetrated by the screw.

Bolting torque: >= 25 Nm torque
Pull-out tension: >= 1,5 t per mounting point
Structural integrity of the frame elements:
2.2-metre span for snow load zone II
1.6-metre span for snow load zone III*

* calculated for the load case: terrain, snow and wind for the greater Munich region, 30° roof pitch. The regulations for snow loads may be found in DIN 1055 Section 5. We would be pleased to send you detailed documentation on structural loading on request.
