How Long Does A 180 Gallon Last?

[BluePhantom]

So I have been wondering how many years an 180 gallon tank will last? like is there a time frame that I need to be more cautious? like if the tank is 10 yrs old or something? thanks for all the help lately!

I have a 25 year old 55 gallon. It has never had a leak (knocks on wood repeatedly). I trust it. Sometimes that stray thought will enter my brain and I will wonder if the seams are still strong.
