The forming unit of heavy bamboo floor is a net bamboo bundle, which is a plate  other material formed by dispersing the bamboo into a long, cross-linked  maintaining the original arrangement of fibers,  then drying, sizing, forming, cold pressing  hot pressing. The characteristics of heavy bamboo floor is to make full use of the inherent characteristics of bamboo fiber materials, which  only ensures the high utilization rate of bamboo, but also retains the original physical properties of bamboo. Heavy bamboo floor can make use of abundant bamboo resources, especially a large number of small-diameter miscellaneous bamboo resources which have  been reasonably utilized. Its density  hardness are much higher than that of flat bamboo floor  side bamboo floor. It is the pinnacle of bamboo floor. The raw material input of single-chip floor is more, so the cost is also high.

The flat pressing bamboo floor is a kind of horizontal combination mode. After carefully cutting, planing  gluing each bamboo piece, it faces upward,  three layers are stacked in parallel. It is put into the high-temperature press. The pressure is  the front  side directions to make the glue solidify  the floor is formed. All the bamboo pieces on the front of the flat pressing bamboo floor have been carefully selected  almost have no defects, because the front of the floor is always facing up, people will touch it every day, if there are defects, it will be ugly. However, the middle layer  back layer of the flat pressing bamboo floor generally choose the bamboo pieces of grade I (for example, the color difference between the bamboo pieces  the bamboo pieces is obvious, the edge of the bamboo pieces is  full, the width of the bamboo pieces is different, the bamboo pieces have small holes, etc.), because the back faces the ground, these defects will  affect the normal use of the flat pressing bamboo floor, nor will they cause structural damage.

The side pressing bamboo floor is a kind of longitudinal combination mode. Each treated bamboo piece is erected,  the side of the bamboo piece is facing up. Because of the large bearing force of the side, it is put into the press after gluing to pressurize  form. Each piece of bamboo in the side pressing bamboo floor is almost perfect, without any defects, otherwise it will directly affect the beauty of the side pressing bamboo floor. The requirements for the bamboo piece are very high, the material consumption is large, the production process is complex,  the quality control requirements are stricter. The direction of wet expansion  dry shrinkage of the bamboo floor under lateral pressure is in the side elevation,  the expansion  shrinkage are only the changes of the thickness direction  size, so the deformation resistance  stability are excellent,  the texture is unique, which is the best work of the bamboo floor.
