The grading of wood flooring using Prime and rustic reflects on the overall look of your Flooring! Although this is an indication of grading with regards to the visual look, this is not the grading in quality. Quality Grading is graded from A grade, AB , CD, CDE & mix grade flooring. At London Parquet all our core ranges are A B Grade with A grade and quarter-sawn available on request.
