Where can an individual (non-contractor) buy wood-product 30' i-beams, and what's the cost approximately? I live in the Seattle nouns, do you just send for lumber...

I live in the Seattle nouns, do you just send for lumber yards? Are these outrageously expensive? Thanks
Answers:    yes they are pricey and abundant yards may not transport them..you may need to name around or use a custom lumber yard.....You may consider ply or laminated or metal or steel beam unless you want them exposed for the look and fiberboard and/or laminated veneer lumber might do the trick if done right......
a i bean you call it is steal not wood i reflect you meant basically a wood beam.... and yes they will be costly what are you planning is what ego like to know you didnt voice what you needed them for and yes you should call a local place or a saw mill
