Flat Steel
Coated with a layer of epoxy, this steel refuses to rust.
Notes
Flat Steel is a tier-5 building block crafted from steel and coated with epoxy to prevent rust. As the highest-tier solid wall material, it is used in advanced construction and is also a component in crafting the Flat Steel Door and Industrial Elevator. Because it requires high-tier industrial infrastructure to produce, players should ensure a steady supply chain for steel and epoxy before relying on Flat Steel for large builds.
