At ClearCalcs, we offer design tools for wood structures that include a variety of products, including glulam. This wood product, consisting of dimension lumber laminations glued together (hence "glu-lam"), is highly standardized, offers efficient use of wood and a great visual appearance.
In general, glulam products are specified with standardized grades set up by the APA. The APA's website offers a vast amount of information on these glulam grades that be accessed for free. There are a few manufacturers that have added custom branding to their glulam grades, but these can generally be matched with standard APA grades. This article serves to collect different manufacturer designations and the APA grade to which they can be matched.
Note that you should **always **confirm design properties and availability with your supplier before specifying these glulam grades.
