Frequently Asked Questions:

What is different about these beams?

PSL Parallams are effectively the strongest wood beams available.  They are made using a long thin strands of lumber and incredibly strong structural adhesive.  When pressed and combined with heat, it makes for a beam that is incredibly strong and predictable.  

Can I use these in a exterior application? 

No.  These are intended or interior applications and should not be exposed to regular water and moisture.  

Can I paint or stain these?

Yes.  PSL Parallams and be painted or stained with no impact on performance. 

Can I drill holes or run mechanicals through these?

Yes.  Holes for electrical, wiring, and mechanicals can be run through PSL Parallam Beams.  Look at the chart below for allowable hole sizes.  

What are the advantages of these beams over other options?  

Single member beam that doesn't require any additional plying or fastening.

Engineered to be perfectly straight with no bow, crook, twist, or warp.  

Predictable and can be safely designed into any structure.  

Resource efficient.  These use thin strands from smaller trees and logs that would otherwise go to waste.  

Can I rip these to size?  

PSL Parallam Beams can be ripped, but by changing the width or depth, you are adjusting the strength rating and potential span and load capability.
