F5 / F7 / MGP10 / MGP12
Applications for structural radiata pine include general construction, joinery, flooring, panelling, plywood, particleboard, fibreboard and paper. Radiata pine structural sizes are planer-gauged to actual dimensions and supplied seasoned / dried. No under size, but a maximum over-size tolerance of 3mm is permitted.
F grades are provided by the visual stress or machine stress grading system. The system provides a set of grades with specific properties. The grades are F4, F5, F6, F7, F8, F11, F14, F17, F22, F27 and F34.
Machine Graded Pine (MGP) is one system of mechanical stress grading and is a more accurate method of assessing the structural capacity of pine. This system provides a set of grades with specific properties. The grades are MGP10, MGP12 and MGP15.
