Pine wood is perhaps the most widely used and known wood. It is due to several factors, among them its abundance, its ease of work and versatility.

It has good indexes of resistance, contraction and flexion and impregnability. It does not stand out in any of them, but the combination is usually good.

pine features

There are many species of pine, each with different characteristics or properties. In this article we will name and detail the main characteristics and uses of the most used types of pine wood.

Some of the most common classes in the carpentry world are:

Pine wood radiata or insignis

pine radiata or insignis

Insignis pine or radiata pine is abundant in northern Spain, Chile and the west coast of the USA, among other places. It is also known in some places as Pino de Monterrey.

Its scientific name is Pinus radiata D. Don.

Characteristics of pine radiata

Color: Wheatish white and yellow to brown heartwood.

Characteristic defects: It has abundant, normally healthy knots.

Fiber: In a straight line.

Grain: Medium to rough

Density: Approximately 500 kg / m3 at 12% humidity. Light to medium weight wood.

Toughness (Monnin): 1.8 – 2.1 soft wood.

Durability: Sensitive to fungi and insects.

Dimensional stability:

  • Volumetric contraction coefficient: 0.44% moderately nervous wood

Mechanical properties:

  • Compressive strength: 434 kg / cmtwo
  • Static flexural strength: 874 kg / cmtwo
  • Modulus of elasticity: 90,000 kg / cmtwo

Impregnation: Impregnable Alburno. Heartwood medium to slightly impregnable.

Workability:

  • Sawn. Easy.
  • Drying. Quick and easy. There is a small risk of cracking and slight deformation.
  • Brushed. Easy.
  • Glued. Easy.
  • Nailed and screwed. Easy.
  • Finish. Easy.

Price: It is a fast growing and abundant wood, so the price of radiata pine is low.

Uses of Insignis pine wood

  • Carpentry assembly.
  • Interior carpentry (doors, windows, moldings, frames …).
  • Furniture, mainly of rustic appearance.
  • Containers and packaging.
  • Laminated wood.
  • Plates: plywood, strips, chipboard, MDF …

Scots Pine or Red Wood

Wild pine

Red or maritime pine is very abundant in Europe, from Spain to Russia. In Spain, it is also known as Pine Soria, because the main farms are in this area. Other common names are Pino Valsain, Pino Flandes, Pino Riga or Pino Alvar.

Its scientific name is Pinus sylvestris L.

Features of wild pine

Color: Pale yellow sapwood and reddish heartwood.

Characteristic defects: Presents knots, small and large, frequent and small resin bags.

Fiber: In a straight line.

Grain: Medium to fine.

Density: 510 kg / m3 at 12% humidity. Light to medium weight wood.

Toughness (Monnin): soft wood 1,9

Durability: It is not durable against insects. Little to medium against fungi.

Dimensional stability:

  • Volumetric contraction coefficient: 0.38% slightly edgy wood.

Mechanical properties:

  • Compressive strength: 406 kg / cmtwo
  • Static flexural strength: 1,057 kg / cmtwo
  • Modulus of elasticity: 94,000 kg / cmtwo

Impregnation: Impregnable Alburno. Heartless little to impregnable.

Workability:

  • Sawn. Easy.
  • Drying. Quick and easy. Small risk of cracks and deformations.
  • Brushed. Easy.
  • Glued. Easy.
  • Nailed and screwed. Easy.
  • Finish. Easy.

Price: between moderate and low.

Uses of red pine wood

  • Internal furniture.
  • Interior carpentry and also slightly exposed as doors, windows, friezes.
  • Platforms.
  • Laminated wood.
  • Carpentry assembly.
  • Plywood panels.
  • Auxiliary elements of construction: formwork, props …

Galician or Maritime Pine Wood

Galician pine

The Maritime or Galician Pine is located mainly in Southern Europe and North Africa. It is also known as maritime pine or maritime pine.

Its scientific name is Pinus pinaster Ait.

Features of the Galician Pine

Color: Light yellowish sapwood and yellow-orange heartwood.

Characteristic defects. It has abundant knots, small and large, and small resin bags.

Fiber: In a straight line.

Grain: Thick to medium.

Density: 530 kg / m3 at 12% humidity. Light to medium weight wood.

Toughness (Monnin): 2.45 soft wood.

Durability: It is not durable against insects. Little or not durable against fungi.

Dimensional stability:

  • Volumetric contraction coefficient: 0.45% moderately edgy wood.

Mechanical properties:

  • Compressive strength: 400 kg / cmtwo
  • Static flexural strength: 795 kg / cmtwo
  • Modulus of elasticity: 74,000 kg / cmtwo

Impregnation: Impregnable sapwood, with little or no heart.

Workability:

  • Sawn. Easy, except when there are resin deposits.
  • Drying. Quick and easy. Small risk of deformation and cracks. Resin exudations are common.
  • Brushed. Easy, except for problems arising from resin bags.
  • Glued. It can be problematic if resin appears.
  • Nailed and screwed. Easy. Requires knockouts.
  • Finish. Problems with resin. You need to clean and apply the bottom.

Price: low.

Uses of maritime pine wood

Outdoor pine wood

This type of wood naturally offers little or no resistance to the usual degrading agents: fungi and insects. Therefore, its use outdoors without protection is far from recommended.

However, pine wood, in most cases, can be treated easily to improve its durability. Perhaps the most common treatment is autoclaving (vacuum and high pressure), which allows us to obtain wood suitable for outdoors in an economical way.
