Overview: Fireproof door is constructed with fire-resistant materials (e.g., steel, gypsum) and intumescent seals to block smoke and flames. Classified by fire rating (30–180 minutes) and opening type (swing, sliding), it provides safe evacuation routes and compartmentalizes fire zones. Essential in hospitals, offices, and factories, it slows fire spread, protects life and assets, and ensures code compliance during emergencies.
