  • Other names: Norway pine, Northern pine, Hard pine, Pitch pine.
  • Scientific Name: Pinus resinosa Alt Genera: Pinaceae
  • Place: New England, New York, Pensenvenia, and countries with lakes.

Physical Properties of Red Pine Wood

  • Color of Wood: This wood differs from light red to reddish-brown. Sapwood is white, and it has a yellowish luster. Sapwood is generally of 50 to 100 millimeters (2 to 4 inch) width.
  • Structure of wood: The slowly growing is clearly preserved in the growing circle of the wood. This wood is called “latewood.” It generally has straight fibers. Unlike the Eastern pine wood, its texture is not so uniform. The wood (mainly the timber tree wood) is slightly resinous.
  • Shrinkage: Moderately large shrinkage. To reach the zero point from the humidity point in the crude state, the radial, tangential, and volumetric shrinkages are 3.8%,7.2%, and 11.3%, respectively.
  • Workability: To work using this wood is simple and convenient.
  • Weight, density, and specific gravity: This wood can be compared to the light Southern pinewood or can be considered equivalent. The specific gravity is 0.41 based on the volume and dry state weight in the crude state. According to the volume and dry state weight, the specific gravity is 0.46 in the state of 12% humidity. In that state, the density is 420 kg per cubic meter (25.61 lb per cubic inch) and 471 kg per cubic meter (28.75 lb per cubic inch).
  • Moisture at green (crude) condition: The wood contains 32% moisture in the timber state, and the sapwood contains 134% moisture.
  • Natural durability: Although the sapwood is more durable than the timber tree wood, both are categorized in the less sustainable class.
  • Seasoning properties: Drying it in the Kiln is not so hard. It can be dried in the Kiln more quickly and flawlessly.
  • Treatability: Although the sapwood is easily preserved in the pressure method, the timber tree wood is not preservable.

Mechanical Properties of Red Pine Wood

The wood is moderately strong and stiff, moderately soft, and moderately high hit tolerable.

  • Modulus of rupture: In the green (crude) condition, it is 40 Newton per square millimeter (5800 lb per square inch), in the 12% humidity 75.86 Newton per square millimeter (11000 lb per square inch).
  • According to the American National Standard and REB standard in the green (crude) condition, the strength of the wood is 45.52 Newton per square millimeter (6600 lb per square inch).
  • Modulus of elasticity: In the green (crude) condition, the modulus of elasticity of this wood is 0.0088 million Newton per square millimeter (1.28 million lb per inch); in a state of 12% humidity, the modulus of elasticity is 0.0112 million Newton per square millimeter (1.63 million lb per square inch).
  • Work to maximum load: In the green (crude) condition, the module is 0.169 kg per cubic centimeter (6.1 per cubic inch); in the state of 12 % humidity, this module is 0.274 kg per cubic centimeter (9.9 lb per cubic inch).
  • Impact bending: In the green (crude) condition and the state of 12% humidity, this module is 66.04 centimeters (26 inches) in height.
  • Compression parallel to the grain- maximum crushing strength: In the green (crude) condition, this module is 18.83 Newton per square millimeter (2730 lb per square inch), and in the 12% humidity state, the module is 41.86 Newton per square millimeter (6070 lb per square inch).
  • Compression perpendicular to grain–fiber stress at the proportional limit: In the green (crude) condition, the module is 1.79 Newton per square millimeter (260 lb per square inch); in the state of 12% humidity, the module becomes 4.14 Newton per square millimeter (600 lb per square inch).
  • Shear parallel to grain- maximum shearing strength: In the green (crude) condition, this module is 4.76 Newton per square millimeter (690 lb per square inch); in the state of 12% humidity, this module becomes 8.34 Newton per square millimeter (1210 lb per square inch)
  • Tension perpendicular to grain-maximum tensile strength: In the green (crude) condition, this module is 2.07 Newton per square millimeter (300 lb per square inch); in the state of 12% humidity, this module becomes 3.17 Newton per square millimeter (460 lb per square inch).
  • Side hardness load – perpendicular to grain: In the green (crude) condition, this module is 154.22 kg (340 lb); in the state of 12% humidity, the module becomes 254.02 kg (560 lb).

Uses of Red Pine Wood

Red pine wood is mainly used as sawing wood, which means lumber. A small amount of the wood is used for the piling of the building, pole of the electrical transmission, distribution and telephone network, cabin logs, posts, the mold of paper, and as fuel.

Like the Eastern White Pine, the Red Pine is used for various purposes. In these various types of purposes, the main purposes are in construction works, side works like making a fence, making the pallets, door, windows, in general works of the factories and boxes, in making the pallets of the ships and the godowns and making the crates are mentionable.
