What about the life of the building? Which one is more durable and long-lasting?I have a 36 x 48 metal pole barn.
wood 6 x 6's and 2 x 6 purlins all around with steel sheeting on the sides and roof.
From a construction point it was quicker and cheaper than wood frame construction.
If your looking at all steel, they are sometimes cheaper, but I like to have some wood to drive a nail in once in a while.
