Plasteel Plates

"A combination of steel and acrylic polymers. Plasteel Plates are useful for light defense, but not effective against heavy weapons."

General
Plasteel Plates are the most basic base armor, and the first one to be unlocked in the game. They are used in beginner-level bases.

Advantages
Plasteel Plates are very cheap to equip, with levels I-II being an instant fit (i.e. build time at most 5 minutes).

They can be used as placeholders while waiting to equip more advanced armors, which can take up to a full day. Something is better than nothing, right?

Disadvantages
Plasteel Plates are worse than their successor, Tritanium Plates, in almost every way. Replace them as soon as you can.

Trivia

 * Plasteel Plates used to share the same name as the ship version, Plasteel.
 * The equipping time of all old blueprint items for bases was reduced by half during the May 2020 update.
