Basic Steel Factory Guide for Satisfactory Tiers 3-4

Your Efficient Starter Steel Factory

Building your first steel factory in Satisfactory unlocks critical progression through tiers 3-4. This compact, scalable design produces 30 steel beams and 40 steel pipes per minute using the Solid Steel alternate recipe – doubling output versus default methods. After analyzing Nikola's build, I've optimized key aspects for clean logistics and future expansion.

Why This Factory Design Works

Steel production is the gateway to Mk.3 belts, industrial assemblers, and tier 4 milestones. The video correctly emphasizes this build's dual role: immediate progression aid and modular component for advanced factories. From experience, I recommend prioritizing the Solid Steel alternate recipe (requiring iron ingots) – it transforms 120 iron ore into 120 ingots, doubling steel beam output.

Core Construction Methodology

Foundation Layout and Preparation

1. Build a 6x10 foundation grid: Center four foundations for machinery, outer rows for logistics
2. Create a sandwich layer: Place walls + 1m foundations above main floor to hide power lines
3. Position three foundries: Face inward, two foundations from platform edges
   Critical step: Remove foundations behind foundries for bottom-fed belts

Production Line Setup

| Input          | Machine        | Output         | Rate (per min) |
|----------------|----------------|----------------|----------------|
| 120 Iron Ore   | 4 Smelters     | 120 Iron Ingots| (Alt. Recipe)  |
| 120 Coal       |                |                |                |
|----------------|----------------|----------------|----------------|
| 120 Iron Ingot | 3 Foundries    | 120 Steel Ingot| Solid Steel    |
| 120 Coal       |                |                |                |
|----------------|----------------|----------------|----------------|
| Steel Ingot    | 2 Constructors | 30 Steel Beams |                |
| Steel Ingot    | 2 Constructors | 40 Steel Pipes |                |

Logistics Optimization

• Input distribution: Use splitters on iron/coal lines before foundries
• Output handling: Merge foundry outputs via mergers onto Mk.3 belts
• Constructor feeding: Loop steel ingot belt around constructors
• Storage solution: Split outputs – 50% to containers, 50% to truck station

Advanced Implementation Tips

Power Management

Conceal power lines in the sandwich layer using wall connectors. This design draws ≈75MW at full load – ensure stable power before startup. I recommend dedicated coal generators for early-game stability.

Scaling and Decoration

While the video shows a basic build, consider these expansions:

• Add encased industrial beam production by feeding concrete to beam constructors
• Vertical scaling: Stack identical floors for triple output
• Aesthetic upgrades: Use catwalks for safe access, windows for visibility, and signs to label sections

Actionable Steel Factory Toolkit

1. Mandatory checklist:

   • Unlock Solid Steel alternate recipe (M.A.M. research)
   • Stockpile 400 concrete for foundations
   • Pre-produce 50 rotors for constructors
   • Upgrade belts to Mk.3 before startup
   • Install hyper tubes along outer logistics rows

2. Recommended mods:

   • Smart! for rapid foundation placement
   • Daisy Chain to simplify power connections
   • Satisfactory Calculator for production planning

Conclusion: Your Gateway to Mid-Game

This factory transforms 240 raw resources/minute into essential progression components. The bottom-fed belt design prevents spaghetti while allowing seamless integration into larger bases. As you expand, relocate the truck station output to motor or heavy modular frame production.
