- The laminating process allows a single, large structural member to be manufactured by laminating a number of smaller pieces of timber
parallel - strand lumber (PSL)
- PSL is a form of engineered wood made from parallel wood strands bonded together with adhesive.
- It is used for beams, headers, columns, and posts, among others uses.
laminated strand lumber (LSL)
- LSL is used primarily as structural framing for residential, commercial and industrial construction.
- Common applications of LSL in construction include headers and beams, tall wall studs, rim board, sill plates, millwork and window framing.
- LSL also offers good fastener-holding strength.
