Pine Framing: When to Use MGP10 v MGP12

Why Pine Framing Grades Matter

Pine framing is the preferred material for Australian residential construction. From single-storey homes to multi-unit developments, structural pine delivers the strength and reliability required to build quality homes.

Pine framing is graded by visual and machine grading. While visual grading is important, machine grading tests the strength, stiffness and density of the timber, ensuring that it meets Australian Standards.

What is MGP (machine-graded pine)?

MGP or machine-graded pine is a structural pine used for wall framing, subframes, roof frames and general framing. It comes in various strengths, however, the most common grades are MGP10 and MGP12. The higher the number, the stronger and stiffer the timber.

MGP10 Framing: Properties & Applications

MGP10 pine is the most common and cost-effective grade used in residential construction. It provides high performance and reliable load capacity for general framing. The benefits of MGP10 include:

• General framing, wall and roof framing or light-load structures
• Lightweight and easy to work with onsite
• Cost-effective and widely available
• Kiln dried to resist warping, cracking and shrinking
• Treated pine option will resist termites, decay and fungal damage
• Versatile and suitable for a wide range of applications
• Sustainable choice

MGP10 remains a popular choice for everyday framing in residential construction.

MGP12 Framing: Properties & Applications

For higher strength, stiffness and greater structural performance, MGP12 framing timber is available. Its benefits include;

• Suitable for larger loads than the MGP10, including general framing, walls, floor joists & supports
• Increased strength and structural integrity
• Similar to MGP10, MGP12 is lightweight and easy to cut, drill and machine
• More expensive that MGP10 yet still widely available
• Reduced waste and costs
• Kiln dried to resist warping, cracking and shrinking
• Treated pine option will resist termites, decay and fungal damage
• Suitable for a variety of applications and comes in a wide range of sizes
• Sustainable timber choice

Selecting MGP12 often comes down to structural and engineering requirements, such as working in high-wind regions, reducing timber centres for ease of build or reducing structural members to reduce labour and costs.

Choosing the Right Grade for Your Project

Selecting between MGP10 and MGP12 starts with the project’s load requirements. Always check the engineer’s specifications and NCC compliance before ordering your timber framing members.
