Trailer Floor- Steel thickness

[KennyO]

Got a project to fix up a mono trailer I bought. Needs a new floor and a few cross members sorted.

What thickness of steel should I use for the floor. It will be used for muck and possibly grain.

Old floor will need cut out completely to do a tidy job I think.

If it for muck go for far thicker as it no extra work to fit it have a grain trailer that is 12mm floor and 8mm for sides but I would do the sides in 10 and keep the sides lower compared to grain sides unless it is sloppy stuff

12mm seems a bit mega

 

[Forever Fendt]

5mm would be ok

Doesn't the thickness required depend on the amount of cross members?

Doesn't the thickness required depend on the amount of cross members?

Also filling method, trailer height, floor material, muck type...

Older grain trailers would only have been 4 mm from new but nowadays 5 or 6 mm would be common for muck 5mm would be plenty but if you are going to use for stone then go thicker but anything above 8mm is in dump trailer category

Whats the grain trailer a shortened Volvo dump truck

It is able to be used as a dump trailer and was one reason for the steel thickness but a heron trailer body is being welded at 5 years old and now need to be replaced at 8 years old and we load with a digger 90% off the time

Ok I see now it’s a double up trailer

yes definitely to many cross members and a thin floor equals dents , You are better with thicker floor and less but stronger cross members so it has a bit of bounce in the floor

Its an old Warwick root trailer. Will be used for cattle fym. Its not going to be sitting loaded with wet sloppy sh1te.

At a guess the cross bearers are about 500mm appart but not measured it. I will get some 5 or 6mm sheets for it I think.

Will post a pic of it later.

Loaded off concrete floors with a telehandler.

Not less than 6mm but get price on various thickness , perhaps get price on galvanised

Bearers are further apart than I remembered. Approx 1m.

 

[Ffermer Bach]

being as labour costs the same, however thick the floor, I would probably err on the side of caution and put in 8mm

changing thread slightly have you any shot blaster near by having it blasted before you start will save a lot of time and makes for easier welding

I would put in extra cross members
