20mm Galvanized Steel Duct Corner for HVAC
The HVAC Duct Flange Corneris a key connecting component used in ventilation duct systems. It is installed at the four corners of a duct flange frame, ensuring firm connection, structural stability, and good air-tightness between duct sections.
Typically made from galvanized steel, stainless steel (SS304/316), or aluminum alloy, the flange corner is designed to match common flange systems such as TDC and TDF. It provides excellent strength, easy installation, and reliable sealing performance, making it widely used in HVAC systems, construction, and industrial ventilation.
Key Features ofHAVC Duct Flange Corner
High Strength & Durability:Made of high-quality galvanized steel with optimized thickness for structural integrity and long-term use, even under high pressure or vibration.
Corrosion Resistance:The galvanized surface provides strong protection against rust and oxidation, suitable for long-term operation in humid or industrial environments.
Easy Installation:Standardized 20 mm (T20) and 30 mm (T30) dimensions make assembly quick, consistent, and compatible with common TDC/TDF duct systems.
Stable Structure:Precisely formed corners ensure tight alignment with flange profiles, maintaining duct geometry and preventing deformation.
