How many grades are there in solid wood flooring?

Three kinds.

The grades of solid wood flooring are generally divided into three grades: A, B and C, in which A is excellent, B is qualified and C is unqualified, which is generally not suitable for the basic listing of C products.

Class A solid wood flooring generally has no defects such as cracks, bug eyes, decay, bending and dead joints. We may find that Grade B solid wood flooring is slightly inferior to Grade A products, but it can still be used. Class C products will basically not appear in the market, but it is inevitable that some unscrupulous merchants will shoddy, which can be directly distinguished mainly by the surface. The surface of Class C solid wood flooring is very rough.
