Perforated metal plank Type BZ
The perforated metal plank type BZ “Zahn” offers a high degree of slip resistance due to its serrated surface structure.
For this reason, the BZ plank is especially suitable in those environments, where fats and oils are used.

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
Connection clamp No. 27

This fixing prevents a different deflection of loaded and unloaded gratings, so a tripping edge > 4 mm cannot occur.
Consisting of:
- Clamp of spring steel
Direct screw connection No. 26
Direct screw connection No. 26
This fixing establishes a secure connection to the substructure, consisting of:
- Countersunk screw M8 x ... ISO 2009 (DIN 965)
- Washer 9 DIN 126
- Nut M8 ISO 7042 (DIN 980), self locking

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.
Consisting of:
- 2 clamping brackets
- Threaded bars with 3 countersunk screws M8 x ... nach ISO 7050 (DIN 7982)
- 2 Olives
Clamp fastening No. 21
Clamp fastening No. 21
Consisiting of:
- Clamping lower part
- Countersunk screw M8 x 20 ISO 2009 (DIN 965)
- Square nut M8 DIN 557
Hook screw fixing No. 22
Hook screw fixing No. 22
Fixing for perforated metal planks on vertical support profiles without bottom flange, consisting of:
- Clamping lower part
- Counter Sunk screw M8 ... ISO 2009 (DIN 965)
- the profile of substructure must be specified upon
Fixing material No. 23 as per No. 22, but with vertical support profiles with bottom flange
S-Clamp No. 25
S-Clamp No. 25
Consisiting of:
- S-hook (fits on a substructure with a 9 mm maximum flange thickness)
- Countersunk screw M8 x ... ISO 2009 (DIN 965)
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
