Truestar provides a wide range of specialized duct systems for projects that require more than standard air distribution. From mild steel (MS) ducts built for tough industrial use, to fire-rated ducts that meet safety compliance, we cater to complex project requirements. Our plenum boxes support uniform air transition, while 4-bolt slip-on flange systems offer structural stability. These components are custom-made, high-strength, and ideal for areas where reliability and compliance are non-negotiable.
