The character of Doorfold partition system materials and components .
① Tracks:Top hung track to carry the panel through the wheel，anodised aluminium 6063-T5,different style for options according to the load weight requirement.
② Wheel：for the carrier and movement of the panel，、high-strength；bearing option from the height of the panel，Screw rod is 45# hardened and tempered steel，Electroplating treament，excellent Mechanical performance and smooth movement to intersection track of“L”、“T”、“＋”type.
③ Wheel seat：the connection with the wheel， 45# hardened and tempered steel，anti corrosive treatment.
④ Top and bottom seal：Bottom seal for the function of the seal between the finish floor and the bottom of the panel.Top seal for the function of the seal between the false ceiling and the top of the panel. anodised aluminium 6063-T5
⑤ Mail profile：the main struction to form the panel；anodised aluminium 6063-T5，surface-treatment options of Powder Coating ,Electrophoretic ,Anodizing Processes according to client requirement.
⑥ Concave convex profile sealor：Embedded magnetic stripe and rubber seal，Total 7 layers rubber seal ensure a high and perfect sound insulation performance.anodised aluminium 6063-T5，surface-treatment Class A

How to form a sound proof movable wall?
The movable wall normally consists of buld seal panel basic panel and telescopic panel.
The first panel is buld seal panel,the last panel is telescopic panel,please see the diagram for better understanding of Doorfold movable partition wall high sound insulation performance
Why Doorfold partition have higher sound insulation performance?What is the difference between doorfold partition system and other suppliers?
More than 13years for the movable partition wall industry
