University lecture hall chairs are designed for use in schools, lecture halls, conference rooms, multimedia rooms, and similar venues.
All welded joints utilize CO2 shielded welding, ensuring the absence of weld failures, cold joints, or burn-throughs, with all weld points ground smooth. All steel tubing undergoes degreasing, derusting, and physical shot-blasting, followed by a high-temperature electrostatic spray coating finish.
