Approved Engineered I Joist Manufacturers

On July 4, 1997, the Engineered Wood Association announced its revolutionary Performance Standard PRI-400. Prior to this program, each engineered I joist had it own set of rules with respect to loads, installation, drilling, etc. It was enough to drive the average carpenter and builder bananas.

Now builders, carpenters, homeowners, and building inspectors have a uniform set of standards, rules and guidelines to follow when specifying, ordering, and installing the I joist products. This is a major step forward for the industry as now the product becomes much more user friendly.

The following is a list of the manufacturers of engineered I joists who make joists that meet the PRI-400 guidelines. I urge you to contact each one and get some information. You will not be disappointed.
