NEW YELLOW PINE
Pine pinaster, Negal Pine, Ródeno Pine, Rubial Pine, Maritime Pine. Pinus pinaster Ait. Syn.
Technological properties
Drying is carried out easily, without flaws appearing, although in Pinus taeda, deformations tend to occur and cracks tend to appear. Sawing is quite easy, although its high resin content may blunt saws, it being necessary to take precautions for sawing resinous woods. Saws with long teeth reduce problems arising from the resin. It is suitable for obtaining rolled veneer.
It is easily machined and blunting of tools is normal. It is suitable for moulding, turning and carving. Repelling may occur in brushing and moulding near the knots when working with high feed speeds and tools which are not sharp. It is not suitable for steam curving due to its high resin content.
Origin and availability
It is found in the south east of the United States (between Virginia and Texas). Its forest masses, production and export are significant.
Description of the wood
The sapwood has a colour which varies from white to pale yellow or light orange. The heartwood is distinguished quite well, as it has a colour varying from orange-yellow to reddish brown or light brown. The growth rings are visible. The summer wood forms very dark bands and the transition between the spring and summer wood is very abrupt outlined with a notable contrast. The wood rays are very fine, not visible to the naked eye, except when included in a transversal resin channel, forming a grain on the surface.
Natural durability
The wood is classified as moderately durable or not durable against the action of fungi, sensitive to cerambycids and anobiidae, and moderately durable or sensitive to termites.
The sapwood is penetrable, and the heartwood has low or no penetrability.
Applications and use
Veneers for decorative coverings. Plywood boards. Indoor carpentry: Flooring, floor coverings, doors, staircases. Construction carpentry. Shipbuilding: Masts. Posts, struts, crates. Paper pulp. Kraft paper.
Consideraciones
There are numerous names for referring to this group of species, which has created great confusion and vagueness.
In Spain, the name applied varies by region: In the region of Catalonia it is called pino melis, in the Balearic and Canary Islands pino tea, and in the Valencia region pino mobila. In practice, there are few who know or use the commercial name.
The name Pino mobila is due to this wood, from the southern United States, being shipped from the Port of Mobile.
Finally, the name Pino tea adds greater confusion. In the UNE 56.504 regulation “Nomenclature of the main conifer foreign trade types of wood”, it is indicated that the name pino tea is applied in Spain to any pine which has a strong differentiation between the summer and autumn wood, with a predominance of the reddish colour; and adds that in the import market it mainly refers to Pinus Palustris. However, other sources indicate that the name pino tea mainly refers to Pinus taeda, and that its origin is due to its suitability for burning as a torch. Additionally, the name pino tea is also used for a type of wood of the Pinus canariensis species, which has a high resin content, which gives it a translucent caramel colour.
