Slide-running design. Door panels are connected end to end through C-type slots. Whole door body can bend flexibly and slide along guide rails with different bending shapes. Benefiting from this design, the door can be fit onto various kinds of door holes. Thus, sectional door is very widely used in all kinds of factories, logistics warehouse, and garages.

Model characteristics

• Excellent wind resistance: Steel sandwich door panel. Surface is double layer color steel. Moddle is filled with polyurethane foam. Wind resistance: Beaufort scale 11, 28 m/s
• Seal: EPDM seal rubber is installed at top, bottom and two sides, gaining good air-tightness.
• Excellent thermal insulation: Total thickness of door panel reaches 40 mm. Density of inside PU foam: 42 kg/m3. With very good thermal insulation performance.
• High-frequency operation: Torsion spring balance system counteracts most drag force during opening. Drive motor works under very light load. Thus there are no overheating and blocking even the door are operated very frequently.
• Convenient operation methods: Standard control button box are available at two sides for daily opreation. Remote control is optional.
• Auto-Manual dual operation modes: When there is power failure or breakdown, the door can be opened or closed by manual operation chain. Balance torsion spring system counteracts most of drag-force of opening. It can be opened by hand with a little force (within 180N).
• Flame retardant: Flame retardant grade: GB8624 B1, EU standard NF-P92-503, Germany standard M2 DIN 4120 B1
• Safety performance: Drop-proof device installed at two sides. Incase the steel wire rope is broken apart, it can prevent the door panel from falling down and avoid accidents. At the same time, safety proximity sensor is installed at the bottom. When there is obstacle under the door, it will stops automatically when touching the objects.
• Various climbing modes: Standard climbing mode; High climbing mode; Vertical climbing mode; Incline climbing mode
• Clear window and small man door for options: Clear window is made from polycarbonate, with high transparency. Small man door is aimed to facilitate human passing, no need opening the whole door
