Wooden production boards are made of properly seasoned high-quality pine wood, offered by the leading producer of this material in Poland. Each batch of wood has a quality certificate and is additionally checked for humidity.
The individual planks of wood are connected by tongue and groove method. To ensure high durability of the boards, they are additionally twisted with bars of precisely selected hardness and thickness (10mm). The bars pierce the board along its entire length in three places.
Thanks to double method of joining the planks by 1) tongue and groove method and 2) threaded bars, boards gain a compact and durable structure. Vibrations from the concrete block machine are better transferred to the concrete mix, which directly affects the quality of the manufactured products. Better stiffness of the boards is also associated with a smaller deflection arrow.
