Does anyone know the name/address of the laminated beam manufacturer Bob used for a renovation in Chicago.

I need a beam span of 30 feet to support a second story, so I won't have any columns inside my garage.

I don't kmow which company Bob used, but to answer your question, look up either Boise cascade or Georgia Pacific. They can give you all the info you need.
Boise Cascade's Web Page is below
