Replying to Telling steal from aluminium rails.

Alright I know a big noob thread. But bear with me..
I know there is another thread thats somewhat related but whatever it a year old.

So I just transferred to a new High School. And it loaded with rails. It has triple kinks, flat rails and the normal down rail. But I cant tell what kind of rails they are (I am a noob I know) So if anyone has pics or can just tell me the difference that would be great.


HAVE A GREAT SEASON NS!
