The tubular chipboard / hollow core chipboard door is named after its unique tubular structure, which is shaped like the bridge hole of the arch bridge.
The tubular chipboard door is an innovation of the door core plate making process and has become a highlight of the interior door manufacturer's products.
It uses the principle of arch bridge hole to process the solid wood sawdust into a unique tubular structure through high-tech process. It can evenly disperse the external force to ensure no deformation. The tubular structure makes the bridge mechanics board 60% lighter than the equivalent solid wood board. At the same time, the bridge mechanics plate can effectively prevent the temperature from spreading and achieve good insulation effect.
Because of its fireproof, soundproof and environmental protection characteristics, the tubular chipboard has become the preferred door core material for domestic high-end wooden doors.
