One of my barns in Florida was a higher end 6 stall metal barn, the other barns were wood. Both had problems.
The steel barns are nice and really pretty I think but mine was not insullated. It should be backed up with interior wood because a horse can easily kick and dent it or just go through it. Mine was so noisey that it would drive me up a wall. It actually hailed there a couple of times and I thought that someone had launched an attack. We had lightening rods of course that were grounded right, but I know of some barns that were hit regardless. So that was always a concern too. It cost a small mint to have it lined with wood. I could have had another barn built for the extra wood that had to be put in it. It was pretty much maintenence free and that was nice. It was not worth the money in my opinion and very overpriced for what it really was. It did look nice and neet though. In today's market, these buildings are priced sky high with the price of metal/steel being what they are and what they have escalated to due to the war. My new barn has no steel in it at all.
The wood barn was old, old, old, a contant repair job. Termites, bugs, rot, you name it. A day didn't go by where I was not out there banging my thumb with the hammer. Wood barns in my opinon do require a lot of upkeep.
For all these reasons and more, this is why Jerry chose concrete for our new barn. It's cost effective and cheaper than going to wood or steel.
Our last dilemna is what to do the inside stalls with now. Jerry would like to use steel rods that he can make in our shop easily and very inexpensively, so that I can have an "open" type barn, and the other option on the table is oak plank boards that they cannot chew. Decisions, decisions.
