Dunnage Question

Two of the shippers that I pick up loads from have racks of creosote treated 4x4 oak. No cost.

 

I carry two hardwood 4x6 I picked up at the matt company I haul for I only use them on the bottom row front and back to take out the arch in my trailer, after that first layer they are not damaging your trailer so I would just use what everyone else requires.

 

buy a 5x5. if your in houston try building products plus tell them your looking for cheap dunage for the trailer. Ask for Mat or Tim

 

Look at my answer for permanent or removal dunnage ( contact me by tex)

You didn't even post a reply, you just quoted someone three times with no response... Nose candy much?

 

Species of wood gives different results for load bearing.
White and chestnut oak are very dense, and offer excellent longevity, wear and rot resistance.
Red Oak likes to rot from the heart outward.
Poplar is lighter, not nearly as dense, but holds up pretty well.
Hard maple is a good in between.
I would pass on soft maple, most cedars, and the like. They don't wear well.
Hickory is strong, and hard as concrete when it's dry.
Ash is a great choice... As long as it's straight grained. No bark at all though... Emerald ash borer quarantine everywhere.
Most sawmills will have piles of 4x4, 4x5, and similar outs for the taking.
