The talk of quality is a bunch of nonsense...
Bought trusses in graded and stamped timber from a quality-certified truss factory here on Gotland (you can google and guess which one).
When I pointed out that several of the installed trusses had long, through cracks in the timber, they just stared blankly at me.
The "solution" they came up with was a bundle of nail plates and a few packages of anchor screws that they handed to me.
Quality, yeah right. :@
