How high is the installation height of the automatic sliding door in the hotel lobby?

The main components of the double-wing revolving door are made of aluminum alloy profiles, ordinary carbon structural steel, high-quality carbon structural steel and section steel. Rubber strip, brush bar and glass glue are used as seals.

Carbon steel: The main materials of the central shaft assembly are ordinary carbon structural steel and high-quality carbon structural steel. The beam subjected to strong force adopts profile. Channel steel or I-beam, with steel plate as connector. The parts with high stress require large bending section, and the use of aluminum profile will increase the cost, and section steel is a better material choice. For parts with less stress, aluminum alloy plates can be used instead of steel plates. All fasteners are carbon steel, and screws, nuts and washers are steel.

The slip ring is made of PVC hard plastic or nylon 66 with good insulation performance. The conductive part is made of brass, silver graphite carbon brush and a small amount of alloy hard materials.
