Plan this output ahead of projects that use it, including Barrel Filler I, Boiler, Distillation Column, plus other downstream targets. Its 8 recorded downstream use(s) help reveal where one stockpile can support several goals; that is a recipe relationship, not a popularity claim.

When it fits: Add it to a project when one of its listed downstream targets is on your plan; combine quantities across those targets before choosing a production run.

The tradeoff: One source recipe run makes 2 and lists 2 Steel Beams at Assembler I / Assembler II / Assembler III; 1 recipe variant(s) for this output are grouped together. Verify access where the pack is incomplete.
