The lumber produced by Daisugi methodology is 140% as versatile as customary cedar and 200% as dense.
Nevertheless it wasn’t all for present: the lumber produced on this methodology is 140% as versatile as customary cedar and 200% as dense/robust, in different phrases it was completely excellent for rafters and roof timber the place aesthetics referred to as for slender but hurricane resistant completely straight lumber. pic.twitter.com/7lKhBHbdvn
