The beams are continuously formed, so the length of the beam is limited only to the maximum length that can be handled and transported. Typical widths are 3 + 1 ⁄ 2, 5 + 1 ⁄ 4 or 7 inches (89, 133 or 178 mm); typical depths are 9 + 1 ⁄ 2, 11 + 7 ⁄ 8, 14, 16 and 18 inches (240, 300, 360, 410 and 460 mm). Typically the beams are made to a ...
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.

Glulam brace with plates used for connections Glulam frame of a roof structure. Glued laminated timber, commonly referred to as glulam, is a type of structural engineered wood product constituted by layers of dimensional lumber bonded together with durable, moisture-resistant structural adhesives so that all of the grain runs parallel to the longitudinal axis.
Grenfell Tower was clad with composite panels with a polyethylene core which contributed to the fire; these panels cost about £2 less than ones with incombustible core. There are estimated to be about 600 high-rise blocks of flats in the UK that have "similar" cladding [ 5 ] and some fire safety tests—not full BS 8414 tests—were carried ...
Popcorn ceiling texture. A popcorn ceiling, also known as a stipple ceiling or acoustic ceiling, is a ceiling with one of a variety of spray-on or paint-on treatments. [1] The bumpy surface is created by tiny particles of vermiculite or polystyrene, which gives the ceiling sound-deadening properties. Mixtures are available in fine, medium, and ...
There is also a patented interlocking tin panel that will screw directly into existing drywall/popcorn/plaster ceilings, without the need for extensive plywood installation. Tin panels today are made in 24-by-24-inch (610 mm × 610 mm) and 24-by-48-inch (610 mm × 1,220 mm) sizes for easier handling and one-person installation.
Wood that has been industrially pressure-treated with approved preservative products poses a limited risk to the public and should be disposed of properly. On December 31, 2003, the U.S. wood treatment industry stopped treating residential lumber with arsenic and chromium (chromated copper arsenate, or CCA).
The steel columns will be connected to the slab by bolting and/or welding them to steel studs extruding from the surface of the poured concrete slab. Pre-cast concrete beams may be delivered on site to be installed for the second floor, after which a concrete slab may be poured for the pavement area. This can be done for multiple stories. [17]
