Auditorium Chairs and Desk Set for University School Lecture Hall

1.Support Leg: Made of aluminum alloy, formed via high-temperature die-casting; features a robust structural design and high load-bearing capacity. The surface undergoes grinding, polishing, wax removal, and cleaning, followed by a high-temperature electrostatic powder coating process.

2.Backrest: Features an eco-friendly MDF core with a double-sided laminated finish. The frame is constructed from high-quality cold-rolled steel, shaped via stamping and CO2-shielded welding, and subsequently undergoes grinding, polishing, derusting, phosphating, electrostatic powder coating, and high-temperature curing.

3.Seat is injection-molded as a single piece from high-quality polypropylene (PP), featuring a solid, seamless structure and excellent load-bearing capacity. It is highly durable, resisting whitening, yellowing, cracking, and deformation over long-term use.The seat supporting is made of aluminum alloy, formed through high-temperature die-casting in a single process; it features a sound structural design and high load-bearing capacity.

4.The fixed tabletop features an MDF core surfaced with fire-resistant laminate; the front edge is finished with a rounded profile (offering greater comfort when resting one's hands on the desk for extended periods, compared to standard straight-edge designs).

5.The crossbeam is constructed from rectangular tubing, with a surface finish achieved through a high-temperature electrostatic powder coating process.

6.Return Mechanism: Features a bilateral dual-torsion spring slow-return mechanism. The bilateral dual-torsion spring design ensures balanced return force and enhanced durability, while the slow-return action effectively minimizes noise during the seat's automatic reset.

7.Bottom-mounted booknet,  high-quality cold-roll steel via welding and finished with an electrostatic powder coating.
