Replacement "C" Channel

I'm in the middle of a floor replacement and I have come across some badly deteriorated "C" channel. Maybe I'm calling it the wrong thing, but its the 3-sided thin channel that bolts to the floor along the entire perimeter and holds the walls of the trailer in place.

Does anyone have a source for this channel or can it be fabricated from the same material as the skins?

If it is not like the channel that mixter has the html tag for then if you take a sample or a drawing with the measurements to you local hvac shop they can cut and bend some for you.

i had a local metal shop make mine on my last projects. btw i made the outside 2” tall and the inside 1” tall.. gives you more room to secure the inside wall.

Thanks, Fellas. Its a simple 3-sided channel. I was wondering if its the same material as the skins. Seems like it is. I like the idea of having it done, and $60 is not too much to pay for a machine to do DIY, but I'm running out of space for this stuff!

I like the extended legs dimension, so I'm wondering if you couldn't bend your own by creating a press of (3) 2x4's. All placed parallel with a pin through each of them at one end . I'm gonna give it whirl and blog it. BTW: I've been blogging my progress on restoring a 1959 Caravanner.

ditto on having the channel made at a local HVAC shop. just take a sample piece. I wish I had thought of making the outside leg taller amazing how many of the original rivets just barely hit or even missed completely. One more suggestion is to go a bit thicker than the original .032. I used .040 and the additional stiffness is very nice to work with and very strong.

If you try it w 2X4s you have to plane one 2x4 down some to get the proper width in the bottom of the channel. If you know someone that does alum siding they can turn out a 100 ft in minutes.

Here's a bundle of channel I had made following the general consensus of the forum. Its 0.040 and the vertical legs are extended an additional 0.50" to catch the errant rivets. I paid $1.70 plf for it and due to a communication slip I ended up with 50 lf of it. I need about 10 ft or so. If anyone can use it, maybe we can work something out. I'm in Tampa, FL.

Front Plate

One area where the channel needs replacing is the front-most section. When I got in there to cut out the deteriorated channel I encountered this front plate. It appears to be some sort of king pin or wind anchor for the entire skin and belly pan. Each are anchored to the plate with (24) 5/32" rivets.

I know this group knows exactly what this plate is so I look forward to hearing from you. Thing is: Before I detached the plate from the skins, it "floated" forward of a transverse strut channel by about an inch.

Did this plate once connect to the channel? or should I reattach it in its current position (about 1" forward of the strut)???

Clockwise from top left:
1) Plate detached on asphalt showing grind marks at rivet points.
2) Backside of skin with plate removed.
3) Plate still attached "floating" about an 1" forward of the transverse strut.

Cant see well on my phone, but Im guessing that is the front hold down plate.I believe that plate should be securely welded to the frame. Important piece.

I'm pretty sure that "plate" used to be an "angle", and was attached to that "transverse strut" (not floating an inch forward), then plywood on top of the missing leg, and then the aluminum c-channel attached to the plywood - nice c-channel by the way . . . someone will want/need it.
