Major preservative manufacturers add a blue (or red) dye to envelope treatments. Blue colored timber is for use south of the Tropic of Capricorn and red for elsewhere. The colored dye also indicates that the timber is treated for resistance to termites/white ants. There is an ongoing promotional campaign in Australia for this type of treatment.
Conservation efforts include keeping the wood submerged and wet since the wooden frame was waterlogged. The conservation of this ship is ongoing. When the waterlogged wooden frame was originally removed from the archaeological site, the timber frames were stored in fresh water vats until June 2017.
A trestle bridge is a bridge composed of a number of short spans. Each supporting frame is a bent. Timber and iron trestles (i.e. bridges) were extensively used in the 19th century. [28] A covered bridge is a timber-truss bridge with a roof, decking, and siding, which creates a nearly complete enclosure. [29]
A common 50 by 100 mm (2-by-4-inch) board. Dimensional lumber is lumber that is cut to standardized width and depth, often specified in millimetres or inches (but see below for information on nominal dimensions vs. actual dimensions). Carpenters extensively use dimensional lumber in framing wooden buildings.
The use of timber framing in buildings offers various aesthetic and structural benefits, as the timber frame lends itself to open plan designs and allows for complete enclosure in effective insulation for energy efficiency. In modern construction, a timber-frame structure offers many benefits: It is rapidly erected.
Braced frame construction, also known as full frame, half frame, [6] New England braced frame, [7] combination frame, [8] is an early form of light framing developed from the heavier timber framing which preceded it. It is defined by the continued use of girts, corner posts, and braces.
In the early 2000s, Brenstol purchased Tre-Timber, becoming the largest producer of thermally modified wood. [ 20 ] At about that time, the market for thermally modified wood expanded dramatically from its traditional application in sauna materials, to include exterior products, such as decking (terrace) [ 21 ] and cladding (siding).

A hammer-beam is a form of timber roof truss, allowing a hammerbeam roof to span greater than the length of any individual piece of timber.In place of a normal tie beam spanning the entire width of the roof, short beams – the hammer beams – are supported by curved braces from the wall, and hammer posts or arch-braces are built on top to support the rafters and typically a collar beam.
