Component Specifications

Definition
A duct panel/body is a fabricated sheet metal component that serves as the primary structural element of duct sections in industrial ventilation, heating, ventilation, and air conditioning (HVAC) systems. It forms the enclosed conduit through which air, gases, or particulate matter is transported between different points in industrial facilities. These components are engineered to maintain specific cross-sectional shapes (rectangular, round, oval) while withstanding internal pressure, external loads, and environmental conditions.
Working Principle
The duct panel/body operates on fluid dynamics principles, providing a smooth, continuous surface that minimizes air resistance and turbulence while containing and directing airflow. It maintains pressure differentials between system sections and supports insulation or lining materials when required for thermal or acoustic control.
Materials
Galvanized steel (0.5-2.0mm thickness), stainless steel (304/316 grades for corrosive environments), aluminum (for lightweight applications), pre-painted steel, or composite materials with fire-retardant coatings. Material selection depends on temperature range (-30°C to +400°C), corrosion resistance requirements, and pressure ratings.
Technical Parameters
  • Fire Rating A2-s1,d0 non-combustible (EN 13501-1)
  • Leakage Class Class A to D per SMACNA standards
  • Joint Strength ≥ 80% of base material strength
  • Surface Finish Ra ≤ 12.5 μm for internal surfaces
  • Pressure Rating 250-2500 Pa
  • Flatness Tolerance ±1.5 mm per meter
Standards
ISO 6944, ISO 7231, DIN 24194, SMACNA HVAC Duct Construction Standards

Frequently Asked Questions

What are the main differences between duct panels for industrial versus commercial applications?

Industrial duct panels typically feature thicker gauges (16-22 gauge vs 24-30 gauge for commercial), higher pressure ratings, corrosion-resistant materials for harsh environments, and reinforced seams for particulate-laden airflow. They also often include access panels for maintenance in industrial settings.

How do you determine the appropriate material thickness for a duct panel?

Material thickness is determined by calculating static pressure, dynamic loads, span between supports, temperature extremes, and corrosion factors. Standard calculations follow SMACNA or DIN guidelines, with typical industrial applications using 0.8-1.5mm galvanized steel for moderate pressure systems.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
