Seismic staboxes follow the same production method as those of the standard range. They are distinguished by longer unfolded steel reinforcements meeting the current requirements for seismic calculation strips.
Indeed, 30% additional reinforcement length is included in overlap with respect to the conventional length in non-critical areas of the structure and 50% more in critical areas.
Steel reinforcements of the seismic range are all category
B500B certified AFCAB.
