Our whiteboard joints are flat and the gaps are extremely small, which will not affect writing, erasing, or the overall appearance. The frame is made of aluminum alloy, which is sturdy, lightweight, and durable. The hooks at the top of the board are fixed and the spacing has been designed after experimental testing to ensure that the board is evenly stressed while maintaining stability. The material of the hooks is also high-quality aluminum alloy, which has extremely high durability.
