StructurePRO Treated Glulam

Sep 2, 2015

We’ve begun sourcing 24F-V5M1 southern pine glulam from APA-EWS member mills and pressure treating it to resist rot, decay, and insect infestation. The glulam beams are treated with Clear -Guard (IPBC + Permethrin) and are warranted for above ground exposure (UC3B).   Our glulam columns are treated with Copper Napthenate (CuN) which is appropriate for ground contact (UC4C). Both treatments are low toxicity.

The design properties are identical to the treated glulam we pioneered and distributed in the Northeast since 2005. Our Technical Department will utilize our iStruct design software for calculations and placement drawings.

If you asked me for a list of the ten greatest suppliers in the industry, I couldn't find ten that are great. Eastern is great - Excellent service, total support, great products, innovative solutions. Don't use them. I don't' want to lose the advantage over you that we get from partnering with them.
