aluminum tubing thickness?

ok, so i noticed there are ZERO people viewing the framebuilders forum, so for the cross-post...

how thick is the tubing of an aluminum frame, specifically the chainstay tube? i scraped it hard on a curb, and it scratched a pretty thick chunk out of the tube. no dent, but a deep gash. should i be worried? it's a Specialized road frame built in 2004, in case that info helps (Specialized Langster to be exact). i'm not sure exactly how deep, but i'll try to measure it when i get a chance.

Bikes: '''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!

There is no specific thickness as frame builders use thick wall tubes of a weaker low-cost alloy for low line frames and thin but stronger alloy tubes on more expensive frames.

Chainstays have heavier walls than the main tubes but will still vary in diameter and wall thickness based on the frames cost and intended use.
