Meh, you don't know true hoarders then. My dad was the type to pick up a washing machine that got hit by a truck off the side of the road, if it even looked like it had compatible valves, bolts, control knobs, switches, whatever.

Daddy collected lots of junk, but it wasn't all exactly junk either. He'd pick something up one day, having no idea what the hell he would eventually use it for, but sure enough, 3~10 years later, we'd find a use for the stuff.

A lot of the scrap metal he found (pipes, pipe clamps, sheets of tin, canvas) went unused for years, just sitting on his property, until he got enough material to build his tool shop (different shop than the Pizza Hut freezer panel storage shed).

I dunno about what OP has there, but I do know that there's two types of hoarders, those that intend to make use of their finds eventually, and those that are just straight up obsessed with collecting junk they'll never use.

Daddy was the planning hoarder, and if he was still here, he'd say OP apparently inherited a hell of a load of useful material. And I'd say go ahead and saw all those weld joints out, stock the long pieces in the garage or wherever, and scrap the welded cuts at a scrapyard for a few extra dollars.

Either way, whether OP has any use in the material or not, you'll get quite a bit more money for it at the scrapyard if the stuff is already cut up into sections that'll fit into their big boy scrap bins.
