v2.6 — added Steel Cell, Iron Cell, Copper Cell, Glass Cell for midgame, Compact Gas Cleaner

This is a set of production cells designed for smelting both metals and non-metals, complete with the necessary supporting infrastructure. The concept is based on standardized block size and layout, enabling flexible combination and scaling according to changing resource demands. Each cell functions as an autonomous unit while integrating smoothly into larger production systems. With a uniform standard length and consistent pipe and storage layout, the system simplifies logistics, streamlines planning, and allows for gradual capacity expansion over time.

Flexibility applies not only to spatial scalability, but also to long-term planning — foundational industrial structures can be established as early as the midgame and will remain valid into the late game. Since the base cell dimensions stay the same, there’s no need for major rebuilds; only certain upgrades may be necessary.

1. Steel Cell

late: https://imgur.com/a/OkEKr1O

This facility produces 144 Steel from Iron ore, Iron scrap and is designed to be as self-sufficient as reasonably possible. It can be easily scaled to any desired production capacity by adding further copies of itself - screenshot https://imgur.com/a/v1z1hUm. It features dual outputs for exhaust and steam, which are currently vented through a backup smoke stack but will later be connected to Industrial Gas Cleaner. The Steel Cell exists in two versions: for midgame and late game.

Note. The facility can also use leftover crushed iron ore — just switch iron scrap for it in the storage. In the cell's logic, it's treated the same.

2. Iron Cell

The facility produces 384 Iron from Iron ore and Iron scrap. The Iron Cell exists in two versions: for midgame and late game.

In the beginning, you can safely pause construction of even half of its buildings — given its high output — while keeping all conveyors, pipes, and storages already installed, and gradually complete them as demand increases. Each Blast Furnace II or Arc Furnace II corresponds to its own set of 2 Metal Casters II, placed in order along it.

3. Copper Cell

The facility produces 192 Glass and prepares all working mixs from basic components itself. The Glass Cell exists in two versions: for midgame and late game.

5. Silicon Cell

This facility produces 576 Silicon (Poly).

Maintenance staff: 176

Despite its compact footprint, the cell delivers massive output. At the beginning, you can safely pause construction of up to 3/4 of its production buildings — just be sure to keep an eye on the paths of the molten channels.

6. Aluminum Cell

The facility produces 72 Aluminum from Bauxite.

Maintenance staff: 174

Note. Future connection of titanium production to the cell is planned via an output molten channel and a balancer. Therefore, it is advisable to position the cell so that the molten channel is directed toward an unoccupied area, free from other cells and infrastructure. These two production lines are planned to be adjacent.

7. Titanium-Steel Cell

The facility produces 108 Titanium alloy and 48 Steel from Titanium ore.

Resource Productivity:

Maintenance staff: 458

Note. The Titanium-Steel Cell is designed to operate adjacent to the Aluminum Cell, from which it receives molten aluminum. A dedicated molten channel runs straight through the Titanium-Steel Cell to serve this purpose. To enable the connection and supply, it’s enough to simply rotate the Aluminum Cell in the correct direction https://imgur.com/a/d3NlUfB.

Theoretically, one Aluminum Cell can supply up to four Titanium-Steel Cells — you just need to align all the molten channels in the same direction. The question is: why do you need so much Titanium alloy? 🙂

Note: In turn, the Titanium-Steel Cell can receive up to 48 CO₂ from the Aluminum Cell for processing into graphite, so their CO₂ storages should be connected directly by a pipe.

Initially, I didn’t plan to launch titanium production, but since this cell turned out to be the most visually appealing of all (though it wasn’t easy to achieve), I’ll probably do it just for the aesthetic satisfaction. It will supply raw materials for trading Composite Core. For example, to fuel this power plant: https://hub.coigame.com/Blueprint/Detail/1022.

Thus, the Metal-Smelting Industry will essentially be self-sufficient in terms of energy supply.

8. Industrial Gas Cleaner

compact: https://imgur.com/a/2BXqOOK

The facility is designed for the treatment and processing of industrial exhaust gases and steam, as well as the waste produced by the settlement, while also supplying the industry with water and even other raw materials. The facility is available in a standard and a compact version.

Note: The cell should be placed so that the water storage is on the same side as the water inputs of the production cells, to facilitate both water supply and gas pipe connections. Accordingly, the storages for sulfur, salt, and graphite will also end up on the appropriate sides for convenient delivery.

Note: This standard setup is also suitable for midgame, as I put in extra effort and built it using up to 450 pipes. The only drawback is that CO₂ recycling won't be operational yet — it will be vented through a Smoke Stack. The construction of the chemical plants intended for processing it should be paused until the appropriate technology is unlocked.

The pipe connection scheme to the cell is implemented through a Pipe Balancer — the upper one for steam and the lower one for exhaust. Accordingly, the produced water can be delivered via a pipe at height level 2 to supply other cells, without blocking vehicle access to the storages: https://imgur.com/a/wof8VrC.

Note: To start the cell, a certain amount of water needs to be delivered. However, once it is up and running, the water storage should be switched to export mode and the output pipes connected.

Note: The cell’s description includes a list of all cells with the exact amounts of gases they emit, making calculations easier. However, the first practical indicator that your pipe throughput is correctly dimensioned and sufficient — and that the cell’s processing capacity is adequate — is the disappearance of the black exhaust smoke from the Smoke Stacks. As you can see in screenshot 2, it has disappeared from all the stacks after the cell was installed.

The industry can not only be able to meet its own water needs, but also supply the entire settlement.

9. Recycling Cell

https://imgur.com/a/uGpHSok

The facility is designed to process up to 720 Recyclables and smelt up to 27 Gold on-site. From a logistics standpoint, it is best to place the facility so that the Recyclables storage is on the same side as the Slag storages of the production cells. This way, for example, a train can deliver Recyclables and Waste in one direction and pick up Slag on the return trip. The sorted scrap can then be fed directly to the nearest production cells via conveyors without delays.

Since the cell has a high processing capacity, most of its buildings can safely be paused at first and completed gradually as the volume of Recyclables increases.
