FIELD OF USE:

• Areas of channels along concave channels with central profile along kerbs
• Point ingress in gullies for rainwater.

MAIN PERFORMANCE FACTORS:

• High level absorption performance :
  • profiled bars, contoured to capture the maximum volume of run off water, confirmed by measurements on test bench carried out at the Saint-Gobain PAM research centre.
  • development of the Expert software, used by our technical teams to help customers design projects, was based on a thorough understanding of the hydraulic performance of the gratings
• Stability and silence in all situations :
  • the frame has a wide support, ensuring stability and safety, on concrete standardised or brickwork chambers
  • safe, silent behaviour when crossed by vehicles. The grating is locked in its frame, with no risk of play or movement, by its ductile cast iron sprung bars
• Ergonomy : the grating can be lifted effortlessly, using the hinge
• Operation : easy access to the networks for cleaning or inspection
• Dissuasion of vandalism : cannot be opened without unlocking tools such as pickaxe or crowbar
• Safety : the non-skid patterns on the grating prevent any risk of pedestrians or cyclists slipping
• Implementation : frame with apertures and wide bearing flange on 3 sides (except kerb side) to ensure efficient, strong and durable installation.
