Product Range and Specialties of Longyou Doortec Automatic Door Co. Ltd

The catalogue focuses on automated entry solutions for commercial and institutional facilities. In the industry, such doors are commonly fabricated from stainless‑steel 304 or aluminium extrusions, equipped with tempered safety glass panels, and integrated with sensor‑based control units that meet IEC 61508 safety standards. Typical performance specifications include opening widths from 1 m to 3 m, load capacities up to 1 500 kg, and fire‑rating classifications of EN 1634‑1 for smoke‑tight operation.
