The appearance quality and machining precision of the test, test whether the floor have a bug (should be less than 1 mm), cracking, rot, mildew, death and other defects. For small live Festival, color should not be too demanding, this is the natural property of wood. The processing precision of simple test, is the scene of a randomly selected 8 to 10 floors on the ground in the assembly, touch and see the quality of its processing precision, smoothness and flatness, the fit between the board and the board (gap joint should be less than 0.3 mm), whether there is a significant difference of height.
Distinguish by the following methods:Choose the color and grain, a lot of people think that the wood is as hard as possible, in fact, hard wood, although it has better wear resistance, but relatively poor dimensional stability, the wood floor size selection, try to choose a narrow and short, although the effect is not as good as the laying of short and wide floor appearance, but from the wood the characteristics, size is smaller, its deformation is small.
