On the "immunity" of a piece of board!

2025-10-08

  This pandemic has heightened public awareness of self-immunity to an unprecedented level. Just as the COVID-19 pandemic has been successfully resolved, the body ultimately eliminates the virus not only through medication but also through our immune system. If our immune system is sufficiently robust, it can effectively combat invading viruses and bacteria, significantly reducing the incidence of disease.

In fact, the same is true for boards. Boards with strong "immunity" can provide stronger care for the family and provide a healthy living environment for the family. On the contrary, boards with low "immunity" cannot provide any health protection for home life. So how do we judge the "immunity" of a board? Let's take a look:

01. "Immunity" comes from good materials.

As we all know, there are many types of raw materials for boards, such as elm, fir, camphor, elm, etc., but most of the wood raw materials have one common feature, that is, the longer the growth years, the harsher the environment, and the slower the growth of the wood raw materials, the more they are the first choice for making boards. Especially now that wood raw materials are scarce, good wood is becoming more and more precious.


RSB lumber is produced using fresh, native timber from the high latitudes of Siberia, Russia, primarily high-quality pine. With temperatures dropping to -40°C and short daylight hours, Siberia's pine grows slowly, with sparse branches located at the tips. This results in fine growth rings, few knots, and low oil content, making it an ideal wood for high-quality lumber.

02. "Immunity" comes from being environmentally friendly.

Nowadays, people are increasingly focusing on environmental protection when renovating their homes. While decorating their homes to look luxurious, they must not ignore the safety of the wood panels. Wood panels with weak "immunity" are not environmentally friendly and can directly affect the health of their families. On the other hand, wood panels with strong "immunity" do not emit harmful substances (such as formaldehyde and benzene), and can strongly protect family life.


During the production process, RSB boards use isocyanate (MDI) formaldehyde-free glue produced by Huntsman Corporation of the United States as an adhesive. The formaldehyde-free and benzene-free process ensures its excellent health and environmental protection performance and quality, which is comparable to natural wood. You can smell the natural pine fragrance when you put your nose close to it.

03. Only when the load-bearing capacity is strong enough can the "immunity" be strong.

The importance of the load-bearing performance of the board in home decoration is self-evident. For example, some load-bearing cabinets, cupboards for storing items, and especially some supports in loft rooms, if the load-bearing performance is not in place, irreparable accidents may occur.


RSB boards are made of high-quality fresh pine wood. They are peeled, cut into regular thin slices, laid, glued, and hot-pressed. They have a large number of long wood fibers. The upper and lower layers are symmetrical with the core layer. The surface wood slices are arranged longitudinally and the core layer is arranged transversely. This overlapping and staggered structure gives the finished product extremely high mechanical properties and internal stability, which can ensure long-term load-bearing.

04. Strong nail-holding ability means strong "immunity".

A board's nail-holding strength refers to the board's ability to grip the nail rod and prevent it from being pulled out by external forces. Nail-holding strength is one of the board's primary physical and mechanical properties. Experienced woodworkers can tell the lifespan of a piece of furniture the moment a nail drives into the board. In other words, a board's nail-holding strength directly impacts the furniture's durability and longevity.


We search for high-quality boards around the world, apply the 5A material selection method, and carefully select Siberian pine with high density and good wood quality. With the support of German production technology, the RSB boards we produce have a three-layer directional structure. This structure reorganizes the wood texture, and has the advantages of being more stable and not easy to deform. The static bending strength and elastic modulus are better than other types of boards, and they have higher strength and more perfect nail holding power.

To have fewer health problems, the internal structure of the board must be good. To be safe and secure, the external structure of the board must be strong. For boards with strong "immunity", choose RSB boards, which are the preferred choice for high-end home decoration customization.
