H Beam Vs I Beam Rods

[BHDave]

Daves stupid question for the month,

After market rods seem to be one of 2 types, h beam or i beam, where as stock rods seem to be all I beam. Other than the obvious different appearance is there an advantage to either of the two?

Cheers

i have been told by a mechanic that the H beam are lighter than the I-beam while still remaining strong.

so are good for revvy engines.

sure there will be alot of different opinions.

We use I beams in engines that we intend to rebuild often, they tolerate more handling and light hits. You can stuff a H beam rod with just the slightest nick. Otherwise no difference in the real world.

i think he means that once you nick a H beam it dramatically weakens its structure as it uses a design to be strong when complete, and the thickness of the H in the rod isn't really thick..

only analogy i can think of is an alluminum can

if your a light weight you can stand on one without it crushing, but if you tap it on its side while on it, it'll crumple real quick..

same sort of principal.

I realise surface imperfections are stress risers, that is the main reason why I polish and shotpeen components.

How do the rods get nicked to start with?
