are those triangle bollards made of steel or concrete? they kinda look like mines
They're not yours, they're Lithuania's.
That gave me a good laugh, my grandfather would most definitely refer to this as a "Groaner".
That's funny because that's what I call your grandfather
Well he's gone now but like him and my dad, I too groan often lol.
Found Russia! :)-
Not hard to find when it's hogging so much space at the top of the map
They should share some of that space. Maybe with the Baltics or Finland?
Steel reinforced concrete

ha, why not both!
Concrete is pretty much always reinforced with steel rebar.
Yep! Concrete is great in compression shit in tension. Steel is great in tension and good in compression but expensive af (reletivly). So u can achieve material properties better than steel or concrete alone at a very efficient price by combining them.
One of god's gifts to man was giving us concrete and steel with the same thermal expansion properties.
I'm pretty sure I read that somewhere.
