LVL is a type of structural composite lumber, comparable to glued laminated timber (glulam) but with a higher allowable stress. [1] A high performance more sustainable alternative to lumber, Laminated Veneer Lumber (LVL) beams, headers and columns are used in structural applications to carry heavy loads with minimum weight. [2]
Engineered lumber can be cut to length and installed much like sawn lumber; the flitch requires shop fabrication and/or field bolting. This, coupled with a much increased self-weight of the beam (11.4 pounds (5.2 kg) for engineered wood vs. 25.2 pounds (11.4 kg) for a flitch beam), decreases the viability of the system.
The main categories of engineered lumber are: [30] 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. They function as beams to provide support over large spans, such ...
The wood is categorized as a board if its width is less than 2 + 1 ⁄ 2 in (64 mm), and its thickness is less than 1 + 1 ⁄ 2 in (38 mm). A plank used in a building as a horizontal supporting member that runs between foundations, walls, or beams to support a ceiling or floor is called a joist.
Cross-laminated timber (CLT) is a subcategory of engineered wood [1] panel product made from gluing together at least three layers [2] of solid-sawn lumber (i.e. lumber cut from a single log). [3] Each layer of boards is usually oriented perpendicular to adjacent layers and glued on the wide faces of each board, usually in a symmetric way so ...
Lumber’s price drop has been particularly dramatic in just the last 90 days in the futures market, with contract prices for July falling 28% to $466 per thousand board feet (futures prices are ...
Hint: The first one can be found in the top-half of the board. Here are the first two letters for each word: SA. PL. CH. JI. LA. VI. DR. WO (SPANGRAM) NYT Strands Spangram Answer Today.
[citation needed] PSL can be made from any wood species, but Douglas fir, southern pine, western hemlock, and yellow poplar are commonly chosen [9] because of their superior strength. The product is manufactured as a 12-by-12-inch (300 mm × 300 mm) or 12-by-18-inch (300 mm × 460 mm) billet in a rectangular cross-section, which is then ...
