4 tips for purchasing core boards

Core board, also known as blockboard, is a type of board material. Made from multiple layers of solid wood, it's incredibly durable and widely used in furniture and interior design. While core board is made of natural wood strips, with a wood veneer on top and bottom, consumers only see the surface of the core board. So how can you choose high-quality core board? Below, we introduce the top ten brands of core board.

1. The surface should be flat and smooth

The most intuitive way to check the quality of core board is to observe its appearance. The outermost layer of core board is the veneer, and high-quality veneer is at least 0.35 mm thick. Veneer produced by reputable manufacturers is generally sanded on both sides, resulting in a smooth, even appearance and no noticeable color variation. When checking for smoothness, consumers should feel it with their hands. The smoother the surface, the more thoroughly the board has been treated.

2. The core board strips should be evenly spliced

The key to the durability of core boards lies in the materials and craftsmanship of the third core board. When purchasing, it is also important to observe the core board structure from the side. When purchasing, consumers should not only check the width of the core board strips, but also whether the two core board strips are tightly joined and whether there are any obvious gaps.

Low-quality core board has loosely joined wood strips, resulting in noticeable gaps. Some manufacturers attempt to conceal this defect by filling the gaps with materials like putty and plaster powder. Consumers should inspect the side of the core board. If any evidence of filler glue or putty is present, this indicates internal gaps or voids.

3. The thicker the middle plate, the more stable it is

From the inside out, core boards can be divided into three layers: core board, middle board, and top board. The second top board of a core board is usually called the middle board, which mainly serves to stabilize the core board strips. Therefore, the thicker the middle board, the better the stability of the core board. If the middle board of the upper board is thin, it may cause the core board to have insufficient bending resistance. The middle board of the lower board should be of appropriate thickness.

To identify the quality of core boards, you can also knock on the surface of the board and listen for the difference in sound. If the sound changes, it means there are cavities inside the board. Such boards have weak overall strength, and long-term uneven stress will cause the board structure to distort and deform, affecting its appearance and use.

4. Check the grade of environmentally friendly board

Core board uses glue when joining the core wood strips and gluing the core to the surface veneer, which releases some free formaldehyde. When free formaldehyde levels exceed a certain level, it can affect human health. Therefore, the key difference between environmentally friendly blockboard and inferior blockboard lies in the quality of the glue.

If the glue used is environmentally friendly, the core board will only have the smell of dry wood, without the pungent formaldehyde smell. If the core board emits a pungent odor, it indicates high formaldehyde emissions. Furthermore, consumers shouldn't just focus on the core board samples provided by the merchant; they should also smell the other boards stacked in the store. Because the samples may have lost their odor due to long storage, consumers should get close to the core boards stacked in the store, especially those in the middle, to check for a pungent odor.
