Let’s break down the different types of ducts commonly produced by Omani manufacturers:
Galvanized Iron (GI) Ducts
The most common and widely used, GI ducts are strong, corrosion-resistant, and suitable for commercial and residential HVAC systems.
Stainless Steel Ducts
Used in industries with corrosive environments (like chemical plants and offshore rigs), these ducts offer superior durability and a sleek finish.
Aluminum Ducts
Lightweight and resistant to rust, aluminum ducts are ideal for marine applications and industrial ventilation where moisture exposure is high.
Pre-Insulated Ducts (PIR/PU)
These ducts come with built-in insulation (usually polyisocyanurate or polyurethane), offering thermal efficiency and faster installation. Widely used in commercial projects and cold storage facilities.
Flexible Ducts
Typically made from metallic foil or plastic, flexible ducts are used in tight spaces or branching points of an HVAC system. They offer versatility but should be used sparingly to minimize airflow resistance.
