Smooth round duct
Smooth ducts are usually made from the following materials:
- Galvanized steel: The most common type, with the outer surface coated with zinc to protect against corrosion and oxidation
- Stainless steel (stainless steel): Includes types such as Stainless steel 201, 304, 316. This type has high quality, good corrosion resistance and hygiene, often used in environments with high humidity, strict hygiene requirements such as restaurants, hospitals, laboratories, food factories.
Outstanding advantages of smooth round air duct
Good ventilation performance: The round cross-section helps the air flow to circulate smoothly, minimizing resistance and pressure loss, thereby reducing the fan's energy consumption.
Noise reduction: The smooth surface and round shape help reduce the impact of the air flow, minimizing the noise generated in the system.
High aesthetics: The smooth, shiny surface helps to enhance the aesthetics of the project, especially when installed outdoors. Can be painted to create decorative accents.
Easy to install and flexible: The round air duct can be easily bent, installed in many different terrain locations, including limited space. Light weight, easy to transport and operate.
Reduced air leakage: Fewer joints than square ducts, especially vertical joints or 4-way joints, increase tightness and reduce air loss.
Less dirt accumulation: Smooth surface minimizes the accumulation of dirt and debris, helping to maintain better air quality and reduce the frequency of cleaning and maintenance.
Cost savings: Lower installation costs than rectangular ducts due to fewer accessories and easier construction.
Pipe length: Ranging from 3.5 to 4m (standard), or longer (3m, 6m, 12m for spiral pipes) to reduce the number of joints.
Pipe thickness: From 0.5mm to 1.2mm (depending on diameter and technical requirements).
Pipe diameter: Diverse, depending on the sheet metal width and usage needs (for example: D80 - D120 is common, can be up to D3000mm).
Galvanizing thickness: From Z8 (80g zinc/m2) to Z18 (180g/m2).
Manufacturing standards: ISO 90001:2025
