This sheet metal housing is designed for high static pressure duct units, providing a rigid structure and reliable sealing for stable operation.
Manufactured through precision cutting, bending, and assembly, it supports custom dimensions, panel layout, and mounting requirements.
The housing is suitable for OEM projects and system integration in HVAC and industrial air handling applications.
Material :
Hot-Dip Galvanized Steel (SGCC) / Electro-Galvanized (SECC)Thickness :
1.0mm – 3.0mm (Thicker gauge for pressure resistance)Surface Treatment :
Galvanized / Powder CoatingProcess Involved :
Laser Cutting, CNC Bending, Riveting, AssemblyProduct Overview
This High Static Pressure Duct Housing functions as a critical airflow management component for industrial HVAC systems. Unlike smaller stamped parts, this large-scale assembly is fabricated from rigid galvanized steel (SGCC/SECC) to resist deformation under high air pressure.
The structure features precision-folded flanges and mechanically fastened seams, ensuring a sturdy enclosure that integrates directly with commercial air handling units.
HPS delivers this unit fully assembled or in flat-pack form, customized to your facility's layout requirements.

Key Features & Advantages
✨ Integrated Access Solutions: Specifically designed with sealed access doors, allowing maintenance personnel to easily inspect internal filters or clear debris without dismantling the ductwork.
✨ Airtight Construction: We utilize Trumpf TruBend machines to create continuous, accurate bends that minimize gaps at corners. Combined with gasket-ready flanges, this design reduces air leakage and maintains system pressure.
✨ Heavy-Duty Material: Built using industrial-grade Galvanized Steel (Zinc-coated) which provides immediate protection against environmental humidity, eliminating the need for post-fabrication painting.
✨ Mechanical Assembly: The housing uses a riveted and bolted construction method. This avoids thermal distortion common in welding and allows for easier modification or repair.
✨ Structural Flanges: Edges are formed into standard TDF/TDC style flanges or angle-iron flanges, ensuring compatibility with standard industrial ducting interfaces.
