I will built a frame for a wood gate like the one below (but mine will slide in a track instead of hang on hinges).
I was thinking on using C-channel instead of tubing for the frame, since it will make it easier to screw the planks to the frame and the screws will be semi-hidden. Also, the c-channel is thicker per weight, so easier to weld with stick eletrodes.
I never saw a gate frame using C-channel, are there any problems using it for that? Apart from the looks on the inside, will tubing provide any real advantage (considering similar weight materials)?
