I built mine like that. 4 foot channel iron with some round bar welded to it. I use them for lots of things. Sometimes I put them on the front of the trailer for a little extra insurance in case I have to get on the binders hard.
I use them the whole trip, since the the top will put down pressure on the bottom ones, with will put a outward force on the straps/chains. Not only is it fighting itself, but the force of gravity.
I hauled lots of pipe including well casing and never had stakes or bars. Is this something new? The pipe was always put on with chocks on each level.
First time I needed them was when I hauled new drill pipe to TX from MN and I hauled used pipe back to MN for refurbishing. Used pipe was not banded together.
It's a cheap containment system for pipe for companies that don't want to invest in real pipe holding equipment or "bunks" to hold them inside the rub rails of the trailer. Kind of an impromptu portable pipe/log racking setup.
When I use mine for pipe I run a chain between them across the deck and use a ratcheting binder to tighten the chain. I've heard of ripping stake pockets if you don't do this.
as long as the cut isn't more then 3/4 inch. it's still useable. i've had two scales tell me that. first one came out and measured.told me to replace. the second was a different state two weeks later when i asked the question.
Old as the hills and Caxpt explained the pipe rack bars are a quick fix, if a trailer is set up for pipe hauling you can make pipe cribs, think a flatbed set up like a log trailer with upright standards.
no, I know what you are talking about. the comment was "most times...." I always had the pipe put on with chocks on each piece on dunnage on each side. when done I threw a couple of straps around in a belly wrap and then strapped every couple of layers. No one ever said anything. I just never had someone insist on stakes.
