Galvanised spiral steel ducting is a durable and long-lasting solution widely used in HVAC (heating, ventilation, and air conditioning) systems. Its spiral design allows for efficient space utilisation, making it ideal for installation in tight or constrained areas, while providing reliable airflow throughout your system.

Manufactured from high-quality sheet metal, spiral steel ducting features a smooth interior surface that reduces air resistance, helping to maintain high airflow rates and improve system efficiency. Compared to traditional rectangular ducting, spiral ducts are easier to handle, install, and integrate into both commercial and industrial projects.

For custom sizes, fittings, or fast delivery, our team can provide expert advice and supply spiral ducting tailored to your specific project requirements.
