quick question when ordering pine framing

Hello, I plan on ordering some 90x45 framing for my shed,



I have seen in bunnings 2 different types of finishes, the type with very small grooves down each side of the wood and the type thats smooth,

do these 2 finishes have certain names? they still both have slighty rounded corners so i dont think they are dar? how would i know what type im getting if i place an order through?



thanks for any help.
