Round & Spiral Duct
Spiral-wound round ducting engineered for stable airflow, reduced friction losses and durable performance.
Description
Round and spiral ducting is designed for efficient airflow with robust structural rigidity. Spiral-wound construction provides consistent cross-section geometry and durability for higher-velocity applications and long-span runs. Manufactured using duct fabrication practices aligned to recognized performance expectations, with connection options suitable for diffusers, grilles and duct fittings. Ideal for exposed or coordinated ceiling layouts where appearance and performance are both critical.
