I-Beam rolls of the tongue H-Beam doesnt, I guess thats the reason for adopting I term over H term

The context was the silent-ness of I vs H, not what rolls off the tongue. I agree that I Pyle rolls better, though.

Too close to Apple's trademarked iPile

My pet peeve along this line is O-ring. Is there any other conceivable shape for a ring?

Doesn't that refer to the cross-section? https://www.allorings.com/x-ring-seals
