Long tongue type lock floor -- because of this kind of floor lock force can reach 1 ton, higher request of base material, USES the European white fir as raw materials, wooden structure uniformity, high density, strong tension, and good stability after processing, tongue-and-groove thin and long and locking force, when the shop is no point of view, the floor and floor flat taps into the slot, on the door frame and radiator edge location of the shop is more convenient.
