The cabinet baseboard is the baffle between the cabinet and the floor at the bottom of the cabinet. The baseboard of the common cabinet is made of aluminum alloy PVC solid wood chipboard, etc.
The commonly used skirting board has three kinds of wooden skirting board, matte metal skirting board and PVC skirting board.
Wooden skirting boards are usually used with solid wood or blister door panels. However, due to the close distance between the skirting board and the ground, wooden materials tend to absorb moisture and moisture, and vapors rise along the skirting board to endanger the entire cabinet. This is why some kitchen cabinets will be "fat" at the bottom of the cabinet after a period of use.
The imported frosted metal skirting board with waterproof rubber is not only waterproof, moisture-proof, moldy, rust-free, but also beautiful and durable, and will not be damaged for life. Most of the cabinets now use aluminum plastic skirting boards, which are divided into one layer and two layers. Height 115MM.
PVC skirting boards are also commonly used, but they are relatively brittle and will age and become brittle after a long time.
