For the safety and protection of the stored goods ( for example luxury cars, watches, jewelry and electronic equipment) , additional burglar-proof measures have been taken at these business premises. Protec Industrial Doors has adapted to this situation by securing the burglar-proof overhead doors with resistance class 4. In addition to the certified door solution according the RC 4 requirements in relation with the EN1627 standard, in this situation is decided to include additional security solutions by for example motion detection sensors. The burglar resistant overhead doors or security gates have no restrictions in terms of functionality and for this project, the security doors are used regularly.
