Product overview
Definition: A TDF flange rectangular duct refers to a ventilation duct with a rectangular cross-section formed by pressing galvanized steel plates or other metal sheets using the common plate flange process.
Product features
Strong structural strength: The common plate flange technology enables the air duct to be formed as a whole with the flange, without the need for welding or riveting, making the structure more sturdy and able to withstand large wind pressure and loads.
Good sealing: Due to the integrated formation of the air duct and flange, the connection is tightly sealed, resulting in low air leakage rate and improved efficiency of the ventilation system.
Easy installation: The common rectangular air duct adopts standardized production, accurate size, strong interchangeability, and does not require on-site processing during installation, which improves construction efficiency.
Beautiful appearance: The surface of the air duct is smooth and flat, with a beautiful and elegant appearance that meets the aesthetic requirements of modern architecture.

Craftsmanship
The production process of rectangular air ducts with common plates mainly includes the following steps:
Cutting: Cut galvanized steel plates or other metal sheets into the required size and shape according to the design drawings.
Compression molding: Using specialized compression equipment, the sheet is pressed into the desired shape and size to form the duct body and flange.
Connection: Special flange clamps or bolts are used to tightly connect the air duct body and flange together.
Reinforcement: Reinforce the air duct as needed to improve its strength and stiffness.
