In dynamic port cities like Hai Phong, high-rise buildings, shopping malls, and industrial factories are constantly springing up. Behind this development, a system acts as a silent "lung": the ventilation and air conditioning (HVAC) system. And for this "lung" to be healthy and operate smoothly, choosing the right supplier is crucial. duct fabrication Reputation and quality are extremely important.
Nowadays, air duct These are no longer just ordinary air ducts. They require high technical precision to ensure stable airflow, smooth operation, energy efficiency, and, most importantly, to meet stringent fire safety standards such as EI. Understanding this, Sao Viet Company (OGSV), with its many years of experience in the field, offers these solutions. manufacturing and processing of air ducts We always strive to provide "Green - Sustainable - Safe" solutions for all construction projects.
This article will help you understand the service better. duct fabricationThe technical standards you need to know and why Sao Viet is the trusted partner of thousands of electrical and mechanical contractors nationwide.
Understanding Duct Fabrication and Common Duct Types Correctly
1. What exactly is ductwork fabrication?
To put it simply, duct fabrication This process involves transforming sheet materials (such as galvanized steel or stainless steel) into pipes of the required shape and size, used for conveying and distributing airflow within a building. The process goes beyond simply cutting and bending; it also includes reinforcing ribs, flange connections, and surface treatment to ensure airtightness, durability, and aesthetics.
At Sao Viet, every step processing All products are manufactured on modern machinery lines, resulting in high-precision products with perfect connections, ensuring smooth and optimally efficient system operation.
2. Common types of air ducts encountered in practice
-
Square/rectangular air duct: This type is the most common in buildings, shopping malls, and basements. Its advantages include easy space utilization, convenient insulation wrapping, and easy fabrication of accompanying accessories. Sao Viet uses Auto Line machines to produce this type of pipe at high speed, with sharp and sturdy bends.
-
Spiral Duct: Popular for its aesthetic appeal, it's suitable for open-air installation in modern spaces such as cafes and offices. Technically, airflow within the round duct is less obstructed, significantly reducing pressure and noise. The spiral winding technology also gives the duct superior rigidity, allowing for the use of thinner sheet metal while maintaining durability, thus saving costs.
-
Fire-resistant ducting (EI Standard): This is a mandatory feature in modern constructions due to increasingly stringent fire safety regulations. (Sao Viet) fire-resistant duct fabrication (EI30, EI45, EI60, EI120) with a special structure and using specialized insulation materials, ensures that the duct maintains its fire resistance for the specified time, helping to extract toxic smoke and supply fresh air to escape routes in the event of a fire.

-
Step 2: Choose the right materials: Input quality determines output lifespan. We only use materials from reputable brands such as Hoa Sen, Hoa Phat (thick Z080 galvanized steel for rust resistance) or Stainless Steel 201, 304 for special environments.
-
Step 3: Processing on an automated production line: Sao Viet factory is equipped with modern machinery systems: Auto Line VI automated machines, CNC plasma cutting machines, spiral pipe bending machines, etc., ensuring maximum accuracy and productivity.
-
