Different Stone Types

[Zeneth]

So, as I usually do, I've started building a large stone "perimeter" wall around my colony. I obviously build it out of stone, but I was wondering, does the type of stone matter? I usually try to use slate (I don't know why), but are certain stone types any better than others?

Select the stone blocks and open info. There is a description about the stonetyp. Granite is harder than the others. For defending steel walls are much better. stonewalls are pretty easy to break through. I use stonewalls later in my inner base, to protect fire.

This is also reflected in time it takes to mine those stones by the way.

According to the wiki there is also a small difference in beauty, with marble being more beautiful. But for walls that doesn't seem to matter

For defending steel walls are much better.

Uh, why is that? All of the stone walls have more HP than steel walls.

Also, rimworld steel is flammable.

Hmmmm...indeed. However, it seems to me always so that the raider faster stone walls can break than steel. First i always used stonewalls and they break through very fast. Now i always use steel and it seems to me its harder for the raider to break it.

You think there's a hidden armor rating or something? That doesn't make much sense.

Slate is actually the second worst stone to build walls of ..
Whenever I forget what to use for walls, I built every type of stonewall I have access to next to each other .. on the other hand, most types of wall are scattered throughout the map anyway-
I never built steel walls, because I need it for so much other stuff, stone on the other hand is plenty and cheap and as stated does not burn.

HP List :

Wood 160
Steel 350
Marble 420
Slate 455
Sandstone 490
Lime 540
Granite 595
Plasteel 700 ( i guess, i have none to look it up right now )

---- EDIT -----
The HP of doors is the same AS WALLS OF THE SAME MATERIAL, but material does influence the open and close speed.

The beauty value of marble makes it usefull for statues and furniture. But remember stuff made from rock takes about 4 times longer to be made.

It does also influence the base damage of traps made from material.

The only time I build steel walls in is in the arctic. And that only at the beginning for the first shelter. Later on it can be replaced by stone.

I'm currently building stone walls in my mountain base. Am I imagining things or does the beauty value of the wall not matter? Seems only floors and objects have beauty. But at the same time pawns don't like bare stone walls I think.

The HP of doors is the same

Not true. Doors also have different values analogous to walls. I tend to make my prison doors out of granite for example.

Fixed my post for you

Yeah, I noticed the same thing. Rough stone walls have a negative modifier while
all other walls seem to have none at all.

[Serenity]

Doh. I misread your sentence Read that way it made sense of course :s

[SpaceDorf]

No problem, sentences always make sense in the head of the author
Thanks for pointing out the unclarity. I hate it myself when important info is represented in a way that leaves it open to interpretations that are opposed to each other.

Plasteel 700 ( i guess, i have none to look it up right now )

---- EDIT -----

---- EDIT -----

Plasteel doors have 700 HP, Plasteel walls have 980 HP. And no, doors have less HP than the walls, a steel door have 250 HP and a wooden one 100 HP for example.

Thanks for clarifying
I was writing from the top of my head without having the data from my current game.

Raiders usually use grenades to get through walls, no? So it probably has to do with that stone takes up to three times more damage from explosions. This according to the wiki at least, but I've also personally observed this since I build walls between the turrets (to prevent chain explosion if one go) - stone walls takes massive damage from a blown turret compared to steel or plasteel.
