You're viewing a single thread.
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.
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.
