Detailed Description

1. Product Overview

Industrial sliding doors are ideal for large‑opening applications such as factory buildings, warehouses, and cold storage facilities. The door panels slide horizontally from side to side, opening and closing without occupying vertical space inside the building. The door panels are made of polyurethane‑insulated sandwich panels, providing excellent thermal insulation, wind resistance, and impact protection. Equipped with a variable‑frequency electric drive, they operate smoothly and quietly, featuring multi‑layered safety protections including infrared sensors and an obstacle‑detecting rebound mechanism. They support a variety of control options, such as remote control, radar detection, and fire‑alarm integration, and are built to be durable and easy to maintain.
