tongue and grove for truck bed floor?

The time has come to replace my old ply wood floor
I have a chance to get some 12 inch wide tongue and grove off of a tractor trailer floor.

Has any one used tongue and grove for truck bed floor on their daily driver?
Can I use it as is? or do I have to worry about expansion. I do not have any bed strips.
Any tips would be great.

Re: tongue and grove for truck bed floor?

The thickness is important, the bed sits on the wood. If the wood is good, and free, I would:
- plane to thickness
- rip to factory widths
- add factory edge details
- add bed strips

Re: tongue and grove for truck bed floor?

While I can't say one way or the other whether it will work, my gut feeling is not very well (without bed strips, and relying on the t&g for longitudinal clamping) - unless you have some other means of holding the floor level/preventing buckling. The bed strips serve the purpose of locking it all in. That would be my only concern, buckling, warping with no longitudinal hold-down mechanism. Possible to get bed strips of someone parting a truck and then rip the 9" planks to size with the appropriate rabbets to make the stock strips work? (EDIT: and jay makes a great point I didn't think about, thickness needs to be correct -I thought semi trailer floors were quite a bit thicker than bed wood, dunno tho)

Re: tongue and grove for truck bed floor?

I was going to go with exterior plywood but am now thinking about 3/4 x 8in x 8 ft pine siding. About $50 for the lumber.

shp4man: 8' lengths aren't long enough for a long bed. In case you have LWB.

Re: tongue and grove for truck bed floor?

Wood expands and contracts across the grain. Using tongue and groove essentially produces a piece of wood 5' wide, which will expand and contract substantially. You can use it but:

-If you put it in during the humid summer months it might be OK.
-If you put it in during winter, leave about a 1/8 - 1/4" gap between boards.

Even at that I think that the gaps are going to fill with dirt, etc during the year and the next time it expands it will likely break the groove.

Not a problem for a garage kept show truck.

What might be cool and within your budget is to use 2 - 3 bed strips with the rest T&G. Will give a custom look.

Re: tongue and grove for truck bed floor?

Thanks for all the input . This is what I wound up getting

They are 1" thick so I will plane them down cut the tongue off seal them with some Thompson seal round up some strips and call it done.

Of all the attempts I've seen at re-doing a bed with something other than stock, this is by far my favorite. I think it's going to look quite good!

Re: tongue and grove for truck bed floor?

Rough cut the planks and laid them out over the old plywood floor. I also got a line on some used bed strips ( or I might try to fab some up, looks like I will need 5 plus the 4 short wheel well ones . Thanks to all of you you for the tips
OEM4ME, hope it turns out ........ stay tuned

Re: tongue and grove for truck bed floor?

That is awesome. Since the wood is laminated it will not swell as bad as a solid board. I bet you could get by with two bed strips.

Is that 18 wheeler bed floor material? It is going to look great.

That's called "Butcher Block" right? Where did you find it?

Re: tongue and grove for truck bed floor?

Thanks I have an idea on making some strips. Was going to use Thompson seal, Marine Spar or linseed oi


Hoping it turns out ! The wood was from a box van that had the floor replaced

Yea looks like butcher block !!

Im thinking of installing an under bed tank while the wood is off too...

Re: tongue and grove for truck bed floor?

So I am not finding anyone who is willing to plane the boards down to 3/4". I was wondering if the following ideas would work. 1st. I could leave the new boards on top of my old plywood and secure them with strips an lag bolts through the plywood floor. Or 2nd. Cut a 1/4 " deep by 1" wide rabbet that would allow the wood to go under the bed frame bevel the edge and secure the boards with strips and blots. Again I appreciate any feedback positive or negative

Why? Understandable if there are random bits of nails or broken screws embedded. It's a hell of a lot of work, but you can do it yourself with a router and homemade surfacing jig.

I wouldn't think you'd have to plane the whole board down to 3/4", but just a grove at the bottom of the boards where the cross supports are.

My idea was to trim the boards to allow them to slide under all the bed sides.

Re: tongue and grove for truck bed floor?

I am doing 1/2 at a time.You can see one board in the rear corner.
The boards are acutely 1 1/8" thick so I used my table saw to make a 3/4 inch cut and one inch rabbet in an extra board and will use it as a guide to set the saw height and with. I am only going to cut down the boards that go under the bed frame and wheel wells the other boards will be left as they are.
I will knock off the edge (round the boards ) and use some diamond plate that I have to protect the board ends at the back of the bed. Still debating on the finish.
