Fastening Material For Grating
Types of Fastening
|
Standard Clamps |
This fastening set permits easy assembly through the grate from above. |
| The safety clamps are provided with a special clamp of which the retaining straps are additionally attached to the transverse bars and secured in position thereon. The bottom part of safety clamps can be supplied with finger hole, at option. This design is provided with a locking device additionally securing the clamp against slipping in bearing bar direction. |

Double Clamps
|
Double Clamps are primarily used for the connection of grates. They prevent displacement of the grates n longitudinal and transverse direction and avoid tripping edges. |
| Hook bolts with short hook serve for fastening of grates in case of angular profiles and/or vertical supports without bottom flange. Electro-galvanized according to DIN 50 961 |
Hook Bolts (Short) |

Welding Bolt Fastening
|
As a rule, fastenings of this type consist of an electro-galvanized threaded bolt to be welded to the supporting structure by means of a bolt welder (according to DIN 32 500) specifically develop for this purpose. Further fastening elements are hexagon nuts and washers and/or clamps. |
| A threaded bolt is forced into the supporting structure by means of a bolt driving tool resulting in some sort of cold welding. With an upper part specifically developed for this type of bolts and called holding flange the grate will be secured on the supporting structure. |

Clamps for Narrow Mesh Widths
|
This clamping set is suitable for fastening grates with narrow mesh widths such as 30x10mm for instance. |
| Upon request, hook bolts with long hook are supplied as a special design for vertical supports with bottom flange such as channel section. Electro-galvanized according to DIN 50 961 |
