Metal profile grating 


The surface of Graepel-Indoor consists of small, embossed, nozzle-shaped holes (diameter of 4 mm) in staggered rows that provide a good slip resistance. This perforation has no drainage effect, but a certain displacement. If drainage is required, the Graepel-City perforation is recommended. The maximum embossed field is 458 mm.


Graepel-Indoor is designed for use in the private and public sectors. The special surface with particularly small holes prevents small parts from dropping through, but provides a certain degree of ventilation. Therefore, this perforation with its small holes is also suitable for housings where heat and air escape in small amounts. Graepel-Indoor can also be used in the industrial sector.
