Duct Installations

Our Types of Ducting

Different industries and applications require specific duct materials and designs:

A. Based on Material

• Galvanized Steel Ducts – Common for HVAC, durable, and corrosion-resistant.
• Stainless Steel Ducts – Used in food processing and pharmaceutical industries for hygiene.
• Aluminum Ducts – Lightweight and rust-resistant, used in clean environments.
• PVC & Polypropylene Ducts – Best for chemical resistance in fume extraction.
• Flexible Ducts – Ideal for tight spaces but should be minimized in industrial settings.

B. Based on Shape

• Round Ducts – Most efficient for airflow and commonly used in industrial settings.
• Rectangular Ducts – Used where space constraints exist.
• Spiral Ducts – Preferred for durability and smooth airflow in industrial applications.

C. Common Mistakes to Avoid

    ❌ Using undersized ducts leading to airflow restriction.
    ❌ Poor sealing, causing energy loss and inefficiency.
    ❌ Excessive bends and long duct runs increasing resistance.
    ❌ Lack of access points for maintenance and cleaning.

D. Installation Process

Proper duct installation ensures safety, efficiency, and compliance with regulations.

A. Planning & Design

• Calculate required airflow and duct size.
• Ensure compliance with local building codes (e.g., AS/NZS 1668 in Australia).
• Plan duct route to minimize sharp bends and resistance.

B. Fabrication & Pre-Assembly

• Custom-cut duct sections to fit design specifications.
• Pre-install dampers, access doors, and insulation if required.

C. Installation Steps

• Mounting Support Structures – Use hangers, brackets, or straps to support ducting.
• Connecting Duct Sections – Use flanges, slip joints, or welding for airtight sealing.
• Sealing & Insulation – Apply sealants or gaskets to prevent air leaks and thermal loss.
• Installing Accessories – Add dampers, filters, and vents as required.

D. Testing & Commissioning

• Perform airflow testing to ensure proper ventilation.
• Check for leaks and pressure drops in the system.
• Adjust dampers and controls for optimal performance.
