Khai Hoan Quan Co., Ltd is comprised of a team of engineers, young and dynamic designers, enthusiastic creators, dedicated and professional individuals, and dynamic creatives with a team of skilled workers who have produced high-quality products to meet the increasingly demanding needs of customers and investors. We have built a reputation in the market, particularly in the supply of ducts, wind valves, cable trunking, etc., for air conditioning and ventilation systems in construction centers, factories, companies, restaurants, hotels, and more.
Our lightweight spiral ducts are made from Hoa Sen steel, with a lower thickness compared to the production of round and rectangular ducts due to our hardening process up to 300.
The round section of the duct allows for 100% airflow, which is much higher compared to rectangular ducts.
We can produce spiral round ducts without any size limitations.
These outstanding features make our ducts widely used due to their quick installation time and reduced consumption of auxiliary materials.
