Spiral Ducting

Spiral ducts are a high-performance ducting solution designed for efficient air distribution in HVAC, ventilation, and extraction systems. Manufactured from durable galvanised steel, they offer superior strength, airtightness, and airflow efficiency compared to traditional ducting. Their spiral seam construction enhances rigidity while reducing air leakage, making them ideal for both commercial and industrial environments. Compatible with a wide range of fittings and accessories, spiral ducting provides a reliable and long-lasting solution for modern air handling systems.

Installation Guide

1. Plan the Layout
   Measure and design the duct route, including fittings and connection points.
2. Prepare Components
   Ensure all duct sections, connectors, and fittings are ready and compatible.
3. Assemble the Ducting
   Join spiral duct sections using appropriate connectors or couplings.
4. Seal the Joints
   Use duct sealing tape or sealant to ensure airtight connections.
5. Secure the System
   Install supports or brackets at regular intervals to hold the ducting in place.
6. Test the System
   Check for air leaks and ensure proper airflow before final use.

FAQ Section

What are spiral ducts used for?
Spiral ducts are used to distribute air in HVAC, ventilation, and extraction systems in commercial and industrial buildings.

Why choose spiral ducting over rectangular ducting?
Spiral ducting offers better airflow efficiency, increased strength, and improved airtightness.

Are spiral ducts suitable for all environments?
Yes, they are suitable for most indoor applications and can be used in a wide range of commercial and industrial settings.
