The Gra31 three-wing revolving door is a stainless-steel 304 frame combined with tempered glass panels, designed for external entrances of hotels, shopping centres and conference halls. It rotates around a central shaft and is offered with inner diameters from 1800 mm up to 3600 mm and corresponding outer diameters from 1888 mm to 3688 mm. The door operates on a 220 V AC supply, with a motor rated at 180 W and an adjustable rotation speed between 0.5 and 4 r.p.m. All dimensions, such as total height of 2700 mm and opening widths ranging 805 mm to 1705 mm, are selectable to match project requirements.
Safety is enhanced by vertical and horizontal sensors, anti-squeeze and anti-strike functions, and a torque-control system that meets European safety norms. The tempered glass typically has a thickness of 10 mm, providing thermal insulation that reduces heat loss while maintaining visual transparency. Energy-saving performance is achieved through the door’s ability to limit air exchange between interior and exterior spaces, a standard expectation for high‑traffic commercial entrances. Optional features include a night-security mode, handicap access, and an integrated decorative display case.
Contractors, project developers and facilities managers source this door for new builds or refurbishment projects where foot‑traffic flow and building envelope performance are critical. The supplier lists the product under building‑hardware imports and can provide custom specifications on request, but exact MOQ, lead time and pricing must be confirmed directly. Buyers are advised to request detailed engineering drawings and certification documents before finalising the order.

Before placing an order, verify the exact inner and outer diameters, total height and opening width required for the project. Request material certificates confirming stainless‑steel 304 grade and tempered glass specifications, as well as safety sensor compliance reports. Confirm whether the door carries any fire‑rating or CE certification relevant to the installation jurisdiction.
Clarify the preferred Incoterm, typical packaging dimensions and the anticipated lead time for delivery from the Ningbo factory. The supplier can arrange containerised shipment, but buyers should confirm vessel schedules and any port‑handling fees at the destination. Payment terms and any required deposits should be agreed in writing prior to production start.
Arrange a pre‑shipment inspection covering visual checks of the glass panels, verification of sensor functionality and a functional test of the motor rotation speed. Request a factory acceptance test report and a copy of the CE or equivalent conformity documentation. Engaging a third‑party inspection agency can provide additional assurance of quality before the goods are loaded for export.
