Grating AUTOLINEA C250 - Dimensions of concrete channels
Introduction:
The AUTOLINEA C250 can be installed on concrete channels with bearer bars or directly on the concrete rebates.
In order to achieve the exact length of the channel, the gratings can be cut as described below.

Implementation on T section frames:
Use of T section frames of 750 mm:
reference E5
T section frames with planarity betweens edges 3 mm and linearity 2 mm
Concrete strength: 10 MPa
Assembling of the gratings:
![]() |
The gratings are easy to install. They are simply snapped into place through a ductile spring lock. The spring bar of the last grating must not be at the extremity of the channel.
Disassembling of the gratings:
![]() |
The disassembling of one or several gratings can be achieved anywhere on the channel. The gap required for the unhooking is obtained thanks to the spring bar.
- Introduce a crowbar between two gratings
- Use the crowbar as lever
- Unlock the spring bar
