Generally, you can find laminated beams in 4-foot increments starting at 24 feet and going up to 44 feet long, with special orders up to 60 feet. LVL beam thickness is usually between 1 ¾ and 7 inches.The headers and beams in the snow load Size Selection Tables (Tables 1-4, 7-10 and 15-18) have been sized using the Design Roof Snow Load shown in the subheading for each table. The Design Roof Snow Load has been derived by reducing the Ground Snow Load listed in each table heading in accordance with

Tables R602.7(1) and R602.7(2) of the code are used to determine allowable spans for headers as well as girders.
