(1) Texture: it is the standard to judge the quality of the floor. Regular texture is beautiful and generous. Don't choose those floors with messy textures.

(2) Color: The high-quality solid wood floor should have natural color tone, clear wood grain and visible materials.

If the floor surface is dark and the paint layer is thick, it may be intended to cover up the surface defects of the floor, especially when the floor is six-sided.

(3) Cracks: Cracks in middle and low-grade floors are inevitable, but it is not good if it is too big.

There are some cracks between the textures of wood, which will not extend and can be used safely; However, some cracks have penetrated the texture, so we must not, because these cracks will extend and have a great negative impact on the future.

(4) Knot: Knot, which can be divided into living knot and dead knot.

Defective joints are not allowed in high-quality products. According to national regulations, all loose joints with a diameter of ≤3MM and loose dead joints with a diameter of ≤2MM are not regarded as defective joints.
