The chance that a freshly spawned container, or a killed NPC, rolls at least one Metal Pipe. Container chances are before inventory limits: a full crate can discard rolled items, while bonus scrap drops beside it.

Component fractions are random rolls; Scrap fractions carry over between cycles. Worn items return less.
