Drake, for the portion of the line running along side the house use steel and it must be painted, for the underground portion it can be polyethylene with manufactured steel risers, sleeved CSST or Type K soft copper (sleeved at the riser at minimum. Steel when used underground needed welded elbows and wrapping with polymer tape, it's a bit much of a hassle compared to the ease of the alternatives. I've not used steel in a buried gas line for somewhere over 17 years. Yellow jacket along the house would look like crap and the sun would deteriorate the jacketing.
