MGP10 Pine Timber

MGP10 timber is the most common structural grade for wall frame and roof truss components. Understand MGP10 timber, common applications and products available.

All timber used in structural applications in Australia needs to be graded in accordance with Australian Standards. Common grades available are F and MGP Grades. F grade stands for Force in megapascals (MPa), while MGP stands for Machine Graded Pine (MGP). It is important to use timber that has been accurately graded because when structural products fail to conform everyone in the supply chain is liable, including the producer, timber merchant, frame and truss fabricator, and builder.

What is MGP Timber?

MGP timber grading was introduced in Australia in 1996 to standardise the quality and performance of structural timber in construction. MPG is a more accurate method of assessing the structural capacity of pine. Machine stress-grading uses a machine to bend each piece of timber, then each piece is individually branded based on the applicable stress grade, for example MGP10, MGP12, MGP15.

The main reasons for the introduction of this grading were:

  • Consistency and Reliability: MGP grading provides a uniform standard for assessing the strength and stiffness of timber, ensuring that all graded timber meets the required performance criteria.
  • Safety: By using machine grading, the risk of human error in the grading process is minimised. This increases the overall safety of structures built with MGP-graded timber, as each piece of timber is accurately assessed for its load-bearing capacity.
  • Efficiency: Machine grading is faster and more efficient than manual grading, allowing for a quicker supply of graded timber to the market. This efficiency helps meet the high demand for construction materials in Australia.
  • Resource Optimisation: MGP grading helps in maximising the use of available timber resources. By determining the strength of each piece, it ensures that timber is used in the most appropriate applications, reducing waste, and optimising resource use.
  • Regulatory Compliance: MGP grading aligns with Australian standards for building materials, such as AS 1720.1 (Timber Structures – Design Methods) and AS 1684 (Residential Timber-Framed Construction). Adhering to these standards is essential for regulatory compliance and for ensuring the safety and durability of buildings.

What is MGP10 Timber?

MGP10 is the common structural grade for the components of a wall frame and roof truss. The 10 in MGP10 refers to the stress grade of the timber, with higher numbers indicating stronger wood. MGP10 undergoes rigorous testing and meets Australian AS/NZS1748.1 to ensure its suitability for building purposes, making it a popular choice among builders and chippies.

Common Applications of MGP10

MGP10 is commonly employed in framing for residential and commercial buildings. It provides structural support for walls, floors, and roofs.

Common applications of MGP10 in wall frame components:

  • Top plate
  • Lintel
  • Still trimmer
  • Bottom plate
  • Head trimmer
  • Head trimmer

Common applications of MGP10 in roof truss components:

  • Top chord
  • Bottom chord
  • Fascia
