The SRGW series of plain butt-welded ducts represents a premium solution for HVAC systems where superior aesthetics, structural strength, and uncompromising air tightness are paramount. Unlike spiral ducts, these are constructed with a longitudinal butt-weld seam, resulting in a perfectly smooth interior and a clean, seamless exterior. This makes them the definitive choice for architecturally sensitive projects with exposed ductwork.
Engineered to meet the highest performance standards, all SRGW ducts are certified for Class D air tightness, ensuring maximum energy efficiency and system integrity.
Key Features & Benefits for Architects and Installers
Aesthetic Finish & Smooth Airflow: The seamless construction provides a high-end, clean look ideal for open-plan ceilings and visible installations. The smooth internal surface also minimizes air resistance and pressure drop.
Certified Class D Air Tightness: Guarantees the lowest possible air leakage as per the EN 12237 standard. This directly contributes to lower energy consumption and optimal performance of the entire HVAC system.
High Structural Integrity: The butt-welding process creates a strong, durable seam along the entire length of the duct, providing excellent rigidity and strength.
Versatile Material Options: Available in galvanized steel, stainless steel, and aluminium to meet the specific demands of any project, from standard commercial applications to corrosive environments.
Standardized Lengths: Produced in convenient 0.5 and 1.0-meter sections, simplifying logistics, handling, and installation on-site.
