Manufacturing with radiata pine

 

Names

 

Common names: Radiata pine and monterey pine

Botanical name: Pinus Radiata

Applications

 

Radiata pine is a versatile and readily available timber, which is suitable for a wide variety of end-use applications.

It has excellent workability, dimensional stability and nail fastening properties. It is tear resistant.

  • Appearance (carpentry, furniture, moulding, sheathing, casing etc.)
  • Structural (construction, moulding etc.)
  • Packaging.

Processing & Coating

 

Radiata pine is easily processed, dried and treated, and will take staining and coating. It is used in conjunction with a range of structural adhesives.

 

Impregnability

 

Sapwood: Easily treatable for all uses, including marine exposure.

Heartwood: Treatable when complying with ground contact standards of use.

Appearance

The heartwood of radiata pine is an even light brown to chestnut brown in colour, the sapwood is creamy white.

It is regarded as a medium density wood with an even texture.
