Production
| Structure | Input(s) | Output | Time |
|---|---|---|---|
 Metalworks Factory (Blast Furnace) | 1 x Processed Construction Materials  66L x Heavy Oil  5 MW of power  | 1 x Assembly Materials IV  | 00:02:00 |
Tier 2 Facilities must be fully researched in the Weapons and Structure

Storage
It does not stack in inventories (1 per slot). It can be stored in the stockpiles of Bases (32k max), Facilities that produces it (32k), Material Pallets (120), Material Transfer Stations (1000), Rooster - Tumblebox Trailer (32), and Small Flatbed Car (100).
It can be crated (need stack of 1 per crate) and uncrated with the right click context menu while interfacing a Seaport, Storage Depot, or Shipping Container.
Crates of Assembly Materials IV can be directly submitted to any item stockpile that accepts that item to transfer their content.The crates can also be stored in the crate stockpiles of Storage Depots (1000 public, 100 per Reserve Stockpile), Seaports (1000 public, 100 per Reserve Stockpile), Shipping Containers (60), or Storage Ships (1000).
It can be transported by almost any vehicle with inventory slots, but is most commonly transported by Trucks, Small Flatbed Car, or shipping vehicles carrying Material Pallets. Delivering it in crate form is possible but extremely inefficient.
