What is F7 H3 treated pine?
A premium quality timber impregnated with a H3 LOSP treatment for protection against insect attacks and moisture decay, making it ideal for above-ground outdoor use, but equally suitable for any indoor application.
Can I use H3 timber inside?
Unlike other “low odour” H3 treated products, T3 Green Plus has no VOC emissions, making it safe for use indoors and out.
Is F7 same as MGP10?
MGP10 has a higher stiffness grade while F7 has a slightly higher strength grade. If plans have been provided, it is important to purchase the exact grade of timber specified to ensure that structural integrity is maintained. If not, you can confidently choose either grade.
Is rough sawn timber treated?
The timber has been cut to size with a circular saw and received no further treatment. This will leave the sides and edges of the timber with a rough, unfinished surface where the saw cut through the wood. Due to the simplicity of preparation, rough sawn timber is always cheaper than planed.

What does F mean in timber grading?
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.
