1. Briefly state the use for each of the following types of engineered lumber : laminatedveneer lumber (LVL ), glue-laminated beams (glulams ), parallel - strand lumber (PSL) , and laminated strand lumber (LSL).

see below

Explanation:

laminated veneer lumber (LVL)

It is typically used for headers, beams, rim board, and edge-forming material.

glue-laminated beams (glulam)

glulam is an alternative to steel or concrete for constructing the roof of buildings such as swimming pools, sports halls and supermarkets. 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.
