Steel is the first thing in Arknights: Endfield that makes you realise your base isn't just "place machine, get item." You can mine Originium and Amethyst whenever you feel like it, but Steel asks for a proper line with clean inputs, or it'll jam up the second you leave to explore. If you're short on time or just want to skip some of the early grind while you learn layouts, it can help to buy Arknights endfield boosting and keep your build momentum going without stalling your whole progression.
Start With The Farm Loop
This sounds backwards, but don't touch metal until your Sandleaf Powder is stable. Steel eats it, and a "sometimes" supply becomes a hard stop fast. Set up a Seed Picking Unit feeding a Planting Unit, then route that harvest into a Shredding Unit for the powder. The part people mess up is seed continuity: run a belt from the Planting Unit back into the Seed Picking Unit so seeds circulate. No loop means you'll come home to dead belts, empty planters, and a factory that's basically decorative.
Keep Inputs Clean And Separate
Once the powder's steady, give yourself space and keep the lines obvious. Use three Depot Unloaders: two dedicated to refined Ferrium and one dedicated to Sandleaf Powder. Don't get clever and combine them. You'll regret it when one item backs up and blocks everything. Put two Shredding Units in front of the Ferrium unloaders so both Ferrium streams get processed the same way. Leave the powder line untouched for now; it's already where it needs to be.
Grinding And Refining Without The Headache
Now build the part that actually makes Steel. Place a Grinding Unit where it can accept all three inputs without spaghetti belts. Route the outputs from the two Ferrium Shredders into the Grinder, then run the Sandleaf Powder unloader straight into that same machine. You're basically blending the shredded metal with the powder, so if one feed is slow, the whole thing feels slow. From the Grinder, send the output into a Refining Unit to finish the process. If you've got a Protocol Stash, connect it after refining so you don't hit a storage cap and silently stall production.
Turn Steel Into What You Really Need
Raw Steel is nice, but most of the time you're after usable products. For building parts, put a Fitting Unit after the Refining Unit and let it run. If you need Steel Bottles instead, swap in a Molding Unit at the end. That last step is the easy, modular bit, so don't rebuild your whole line just to change outputs.
