Channel Grating - Gratings for Open Channels -U-ditch and Gully Grate Panels

Channel Grating is a one-piece metal plank grating manufactured by cold forming steel into a channel shape structure offering much higher strength and ductility than traditional cast iron grates. The walking surface has square, diamond or other holes to create a grip surface and to allow for the dissipation of water and debris, suitable for large span and heavy loading sewage system, well covers and gully covers, used in docks, airports, seaports, and various engineering projects. Also called Ditch Grating, U Channel Grating or Gully Grating.

Galvanized channel gratings have following advantages over cast iron:

Hot-dip galvanizing against corrosion, less maintenance needed and easy replacement;
Security design available: box with hinged lid and connection, security, safe, easy to open;
Large span grating cover saving investment using the lowest ratio of iron materials;
Higher strength than cast iron, can be used for terminals, airports and other large span and heavy load environment;
Full specifications, more sizes and shape options provided meeting different environment and loading requirement.

We supply channel steel grating with standard ASTM A 27, 47, 48, 283, JIS G 3101.
We can design and manufacture standard channel grating and special grating in customized shapes per client's requirements.
