It is widely known that when more than one web hole is present, the holes can interact and further reduce the load-carrying capacity of an I-joist
, compared with a single web hole of the same size, if the distance between the holes is small.

The current North American I-joist
market is estimated at $1 billion annually with projected market potential of $2.5 billion Anthony Forest's trademarked Power Joist Wood is described as being one of the leading edge engineered products on the market.
The wood I-joist
floor design consists of an OSB web and LVL flange with plywood decking.
But after the first time, the steel floor process takes no longer than a solid-sawn wood or engineered I-joist
"But Trus Joist could put in an I-joist
plant down the road" if things go well, Brennan adds.
The meeting consisted of a full day of technical sessions followed by a day of plant tours including the Norbord I-joist
plant and the J.D.
For example, when comparing an OSB web I-joist
to a plywood web I-joist
, the OSB web I-joist
offers a higher shear performance, says Mike Hunsaker, general sales manager for Willamette's engineered wood products.
The mill will produce a high-quality solid sawn flange I-joist
, trademarked in the Anthony product catalogue as the Power Joist.
APA (www.apawood.org) represents approximately 160 plywood, oriented strandboard, glulam timber, wood I-joist
, laminated veneer lumber, and other engineered wood product mills in the United States and Canada.
Applying a few key principles to I-joist
installations means never having to say you're sorry.
-- AWC submitted a total of five generic I-joist
assemblies and two wall assemblies for inclusion in the code.
