Perforated metal plank Type BN-GA
The surface of the perforated metal plank, type BN-GA “Noppen, geschlossen, Ablauflöcher“ is a mix of closed punched nobs facing upwards and conical drain holes facing downwards. This means that the grating does not have any sharp edges on top and can be walked on easily even without footwear. At the same time, however, any liquids can be quickly drained through the conical drain holes so that no hydroplaning can occur.

- Washer 9 DIN 126 and nut M8 ISO 7042 (DIN 980), self-locking
Element butt fixing No. 27
Element butt fixing No. 27
This fixing prevents formation of tripping edges on non-bolted elements with large spans and increases the load distribution
Consisting of:
- Connection part
- Thread forming screw M5 x 20 DIN 7516
Clamping claw No. 34
Clamping Claw No. 34
This fixing is used for fastening of perforated metal planks on the substructure. Through the screw M12 with an appropriate tightening torque, the grating is pressed with defined clamping force on the steel construction. As a result, a defined horizontal force is transferred and secures the gratings against lifting. Consisting of:
- curved flat 50 x 8 mm
- Screw M12 x ... ISO 4017 (DIN 933)
- Washer 13 DIN 126 and nut M12 ISO 7042 (DIN 980), self-locking
Butt joint No. 24
Butt joint No. 24
This fixing is used as borehole-less fastening of perforated metal planks with simultaneous distancing to the substructure.
Consisiting of:
- 2 clamping brackets
- Threaded bars with 3 countersunk screws M8 x ... nach ISO 7050 (DIN 7982)
- 2 Olives
Angle fixing No. 30
Angle fixing No. 30
This fixing prevents displacement of perforated metal plank. Consisting of:
- Bracket piece 30/30/3 ... 50 mm long
- 2 thread-forming screws M5 x 20 DIN 7516
Butt strap No. 31
Butt strap No. 31
Suitable for connecting grating elements together at thrust and areas of restricted load transmission.
