The door leaf side edges adopt a single-seam close-fitting interlocking structure, providing anti-loosening performance. The entire door leaf surface has no exposed screws, rivets, welding spots, or welding positioning holes, effectively improving surface quality and ensuring reliable performance in various environments.
The internal core is filled with thermal-insulated flame-retardant extruded board. The door leaf is lightweight, with good strength and flatness, and is resistant to deformation caused by moisture.
The wood grain finish can be achieved through heat transfer printing on steel sheet or by applying PVC film on the steel sheet surface. Customers can provide color samples for customized finishes.
The door frame is equipped with an R-shaped airtight groove, with a removable airbag-type sealing strip embedded inside. It provides shock absorption, sound insulation, airtightness, and smoke control, effectively reducing noise when opening and closing the door.
