This magnetic baseboard serves users with easy and efficient installation. Consisting of an aluminum alloy panel and a metal back plate, it allows glue-free fixation via the magnetic attraction approach, making it safe and easy for users to assemble and disassemble, as well as avoiding the health hazards of formaldehyde. Also, these panels can be seamlessly connected by connecting fittings, and adopt the streamlined appearance and smooth bevels to effectively prevent dust accumulation. Additionally, the aluminum alloy used improves durability and extends the service cycle of the baseboard.
