Product Description
This general‑purpose sectional overhead door is developed for ordinary manufacturing workshop building openings. Insulated PU sandwich panels together with galvanized heavy‑duty hardware deliver stable daily operation. Equipped with complete multi‑safety protection mechanisms, it balances thermal insulation, wind‑proof sealing and cost‑efficiency for regular industrial building projects.
The standard sectional overhead door adopts upward‑sliding sectional panel structure. Panels run along curved track and turn flat under ceiling after opening, saving ground space. It works for indoor‑outdoor separation of factory workshops. The whole set adopts mature and stable configuration, suitable for most general‑industrial scenarios where no extreme low‑temperature or heavy corrosion environment exists.
40mm thickness as standard option, steel sheet outer skin with powder coating, inner filled with high‑density PU foam for thermal insulation and sound reduction. 50mm reinforced panel is available upon request.
Hot‑dip galvanized track, hinges, roller brackets and torsion spring balance group, good anti‑rust performance for normal factory environment. Sealed rollers reduce operating noise.
AC industrial motor with stable output torque; basic control includes push‑button box and remote controller; extended access‑control sensors can be added on demand.
Safety bottom edge, infrared photoelectric sensor, spring‑break protection device, mechanical upper‑lower limit prevent accidental injury during door movement.
EPDM rubber sealing strips installed on top, side and bottom positions, lower wind dust and noise transfer between inside and outside workshop.

- Mature stable configuration, cost‑effective solution for general factory workshop
- Upward sliding structure saves floor space, no occupation to ground passage area
- PU insulated panels achieve basic heat preservation and noise reduction performance
- Complete set of safety devices guarantee daily operation security for site staff
- Rich optional configurations: vision window, wicket door, high‑wind‑resistance reinforcement, various RAL color options
