Yellowish-white with a slight brown, the growth rings are obvious, the wood body is pure and thin, slightly heavy and hard, and the structure is fine. The birch growth rings are slightly obvious, the grain is straight and obvious, the material structure is delicate and soft and smooth, and the texture is soft or moderate. >>>More

Birch is not dense and relatively soft. But Jiusheng's solid wood flooring is of good quality.

I prefer catalpa, I think the cost performance is higher, the price of red oak is too high, and other woods are not as good as catalpa!

It is not suitable for birch to be directly used as solid wood flooring, and it can be made for solid wood flooring because of the high mechanical strength, elasticity, hygroscopicity, dryness, cracking and warping. It is not very durable in an environment that is prone to decay, and the production materials of solid wood flooring require hard texture, wear-resistant surface, and good stability, which are undoubtedly contrary to the performance of birch. Birch itself is known for being easy to process, and combining some man-made panels to make parquet can not only save costs, but also the wood grain of birch is better than the wood grain of many hardwoods, so birch is often used to make parquet.
