Fire retardant overhead doors have been installed in the Ajax Amsterdam Arena. They are situated on the stadium corners of the Amsterdam Arena. In the corners between the grandstands, there are large passages for transporting material to the pitch such as the various materials needed for the maintenance of the pitch or equipment used for concerts or other events. These firedoors function in the same way as standard overhead doors, applied in fire walls as well as façades. Your business process is hardly restricted while complying with the set standards.
