Because I wonder about these things, I really can't see the economic philosophy behind the pretty stainless steel caps on this picnic shelter. All the fittings are stainless steel, and I can see that the caps protect the protruding timber from deterioration due to the ravages of the weather, but wouldn't it have been simpler, and more "honest" in a design sense, to simply cut off the overhangs so they weren't exposed in the first place?
I suspect that without the stainless steel, there would have been enough budget for two shelters!
