RE: Detail Review

I always thought that PSL lumber was fabricated with long fibers oriented in the direction of the member giving it a superior strength in the longitudinal axis.  If that is the case then the cross-grain axis would not have the advantage of those same properties although the “weak axis” – still in the longitudinal direction, would have the same strength.  It would be nice to hear some input from TrusJoist.

The light has come on for a while....Did Trusjoist have any concerns about bending at the cantilevered part of the PSL.  After watching the manuf. of PSL's there doesn't appear to be any strong or weak axis. The plywood veneers are randomly assembled, compressed, and mico-waved all at the same time.
