LVL is considered to be a highly reliable building material that provides many of the same attributes ...
Laminated veneer lumber (LVL) – LVL comes in 1 + 3 ⁄ 4-inch (44 mm) thicknesses with depths such as 9 + 1 ⁄ 2, 11 + 7 ⁄ 8, 14, 16, 18 and 24 inches (240, 300, 360, 410, 460 and 610 mm), and are often doubled or tripled up.

The plank was the basis of maritime transport : wood (except some dense hardwoods ) floats on water , and abundant forests meant wooden logs could be easily obtained and processed, making ...
