Commercial Grade

[Steeling]

Metal building companies seem to take great pride in the fact that their buildings are "100% commercial grade re-iron steel". But what does that mean? Comercial grade as opposed to what other grade? Red irron steel as opposed to what other kind of steel?

Commercial grade means it can stand up to heavy use and abuse. I think the red iron first came about as to forging temperatures to acheive maximum strength and quality.

Thanks for cleaning that up metalwiz. When I first saw "re-iron" I thought it was a new invention. But it's red iron-ok.

I take your word for it guys.
