Jeffrey pine wood and ponderosa pine wood are sold together as yellow pine. [6] Both kinds of wood are hard (with a Janka hardness of 550 lbf (2,400 N)), but the western yellow pine wood is less dense than southern yellow pine wood (28 lb/cu ft (0.45 g/cm 3 ) versus 35 lb/cu ft (0.56 g/cm 3 ) for shortleaf pine).
Pinus taeda, commonly known as loblolly pine, is one of several pines native to the Southeastern United States, from East Texas to Florida, and north to southern New Jersey. [2] The wood industry classifies the species as a southern yellow pine . [ 3 ]
Wood uses historically were determined by its particular characteristics, e.g., 0.43 mean specific gravity nearly equal to Douglas-fir (Pseudotsuga menziesii); strength properties similar to ponderosa pine; Kraft pulps high in bursting with tensile strength comparable to some northern conifer pulps; and foothill stands loggable in winter, when ...
It contains ripe wood in the outer crust. The colour of this ripened wood is dark brown. It is strong, durable and fibrous. Palm is used for furniture, roof covering, rafters and joists. Pine: Pinus spp. Pine wood is hard and tough except white pine which is soft. It decays easily if it comes into contact with soil. It is heavy and coarse grained.
[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 ...
There is a strong relationship between the properties of wood and the properties of the particular tree that yielded it, at least for certain species. For example, in loblolly pine, wind exposure and stem position greatly affect the hardness of wood, as well as compression wood content. [30] The density of wood varies with species.
Southern bleached softwood kraft (SBSK) is a wood pulp mainly produced in the southern USA. The main raw materials are slash pine , longleaf pine , shortleaf pine , loblolly pine and virginia pine .
Pinus elliottii, commonly known as slash pine, [2] [3] is a conifer tree native to the Southeastern United States. Slash pine is named after the "slashes" – swampy ground overgrown with trees and bushes – that constitute its habitat. Other common names include swamp pine, yellow slash pine, and southern Florida pine. [3]
