ABSTRACT:
A floorboard system includes a plurality of floorboards, wherein each of the floorboards is a rectangular floorboard provided with long edges and short edges and having a floorboard body provided with an integrated long edge locking system and an integrated short edge locking system for mechanical joining, both vertically and horizontally, the floorboards, along the long edges thereof and along the short edges thereof. The long edge locking system differs from the short edge locking system in respect of at least one of material composition and material properties. And, at least one of the long edge locking system and the short edge locking system includes a separate element which is integrally connected with the floorboard body at the factory and is made of a material other than that included in the floorboard body.
