Fire incidents in commercial and industrial buildings often start or spread silently through HVAC ducts and vertical shafts. Flames and smoke can move rapidly, putting lives, property, and compliance at risk. Without proper fire-rated protection, even a small fire can escalate into a major disaster.
Our duct doors are designed to provide easy and secure access to duct systems for maintenance and inspection. Built with high-quality materials, these doors ensure durability and safety in industrial environments. We also offer fire shaft door solutions that are suitable for vertical shafts and service areas, helping maintain safety compliance while supporting efficient building operations.
At MPS Techno Fab, we are a trusted Fire Duct Door Manufacturer in Pune and across Maharashtra. Our doors comply with NBC 2016 and IS 3614 standards, offering up to 120-minute fire resistance to safeguard your building, occupants, and infrastructure.
We address real-world challenges like smoke leakage, fire spread, and maintenance hurdles while ensuring regulatory compliance. Whether it’s a high-rise commercial complex, hospital, industrial plant, or IT park, our fire-rated solutions combine durability, precision engineering, and local expertise.
Fire Duct Door: A fire-rated panel installed on HVAC ducts to prevent flames and smoke from spreading while providing maintenance and inspection access.
Fire Shaft Door: Heavy-duty doors installed in vertical shafts, such as lift shafts, electrical shafts, or utility shafts, preventing fire from spreading between floors.
These doors are a critical part of passive fire protection systems, containing fire within designated areas and protecting evacuation routes.
