H2 treated pine is specially treated to protect against borers and termites and is suitable for interior, above-ground use only.
Is MGP10 treated wood?
typical MGP10 is not treated .
Is mgp10 timber treated?
Timber is treated to H3 standard (outdoor above ground applications) and is compliant with AS1604 preservative treated timber. The Light Organic Solvent Preservative method produces a dry and dimensionally stable product that is available for application immediately after completion of the process.
What is MGP10 timber?
Machine-graded pine MGP, MGP10 to MGP15: E.g. MGP10 indicates a minimum threshold for stiffness properties of 10,000 MPa . Most exotic plantation softwoods (Pinus species) are graded using this system.
How can you tell if pine is treated?
Generally any softwood (pine) that has been in the open for more than a year and has not rotted will have been preservative treated . Any hardwood such as power poles which have intact sapwood (the outside of the tree) will also have been treated.
What is stronger F7 or MGP10?
MGP10 has a higher stiffness grade while F7 has a slightly higher strength grade . ... Stiffness measures how much a beam will deflect for any given load and is related to density, fibre quality, moisture content and pine defects. MGP10 measures 10.0GPa (gigapaschals), while F7 measures lower, at 7.9GPa.
What does MGP10 4 mean?
The term MGP refers to machine-graded pine . The more stress the pine can handle, the more MGP it will have. And the number that goes after MGP refers to the threshold of stiffness. For example, a threshold of 10,000 MPa (megapascal), means you’re looking at an MGP10 piece of wood.
What level is timber?
Laminated Veneer Lumber (LVL)
Laminated Veneer Lumber is created using multiple layers of thin wood which is bonded together with heavy-duty glue. Because of the strength of the glue, engineered lumber is more stable and resistant to common problems like rot, termite infestation and mould.
What is F grade timber?
An F grade is a measure of the bending strength of a piece of timber . ‘F’ stands for force in megapascals (MPa), and is the amount of force a piece of timber can withstand without bending beyond an acceptable limit. A piece graded to F11, for example, will have a safe working stress in bending of 11 MPa.
What are the grades of timber?
| Type of wood product grade Wood type | Dimension planed wood G4-2 – G4-3 Spruce and pine | Construction timber G4-0 – G4-2 Spruce and pine | Sheathing G4-2 – G4-3 Gran | Formwork G4-4 or better Spruce and pine |

What are the 3 methods of grading timber?
- Visual stress-grading.
- Machine stress-grading.
- Machine proof-grading.
What does the H stand for in timber treatment?
Look for the “hazard class rating” on each stick of timber. The hazard class rating H1 to H6 tells you the level of treatment you need for the job in mind. For moderate decay situations where timber is exposed to the weather but is not in contact with the ground. ...
What is the most durable timber?
The Janka hardness rating for Brazilian Walnut is a whopping 3680, making it the hardest and most dense of all the woods we’ve discussed. The colors in this ultra-hard timber range from light blonde to deep brown.
How can you tell if old wood is treated?
How can you tell if wood is treated? Pressure-treated lumber has end tags or stamps identifying the chemical used. It can have a green or brown color from the treating process. Treated wood can smell oily or chemical as opposed to a nice natural smell of untreated wood.
How can you tell if pressure treated wood is dry?
To determine if pressure treated wood is dry enough to stain, try the “sprinkle” test . Sprinkle water on the wood: if the wood absorbs it within 10 minutes, plan to stain as soon as possible. If the water beads or pools on the wood surface, the wood needs more time to dry.
Is treated wood toxic?
If you follow safety precautions around treated wood, you should not have any health effects as a result . However, you should avoid exposure to the smoke or ash from burning treated wood. If you suspect poisoning, seek medical attention immediately.
