An M.S. (mild steel) duct is a crucial component of ventilation systems, commonly used in commercial, industrial, and residential buildings to facilitate the flow of air. Made from mild steel, these ducts offer strength, durability, and resistance to corrosion, ensuring long-term performance in diverse environments. M.S. ductwork is fabricated in various shapes and sizes to accommodate specific airflow requirements, utilizing techniques such as welding, bolting, or riveting for assembly. These ducts connect air handlers, vents, and outlets, efficiently distributing heated or cooled air throughout the building. Properly designed and installed M.S. ductwork contributes to optimal indoor air quality, comfort, and energy efficiency.
