Custom Fire Damper Blades: How Roll Forming Delivers Precision & Flexibility

The Need for Custom Fire Damper Blades

Fire dampers must be tailored to specific HVAC system requirements, including:

• Duct size and shape (rectangular, circular, or oval)

• Fire resistance ratings (1-hour, 2-hour, or 3-hour)

• Airflow efficiency (minimal restriction when open)

• Material durability (galvanized steel, stainless steel, or aluminum)

Roll forming allows for precise, repeatable production of damper blades that meet these exact specifications.

1. Precision Bending for Complex Profiles

• Roll forming machines use CNC-controlled rollers to shape metal coils into exact damper blade profiles.

• Tolerances as tight as ±0.1mm ensure consistent performance.

2. Material Flexibility

• Works with:

  • Galvanized steel (most common, cost-effective)

  • Stainless steel (for corrosive environments)

  • Aluminum (lightweight applications)

• Handles thicknesses from 0.5mm to 2.5mm.

3. Custom Hole Patterns & Perforations

• Pre-punching options for:

  • Mounting holes (for frames and actuators)

  • Airflow optimization (perforated blades)

4. High-Speed Production Without Sacrificing Quality

• Produces 10-25 meters per minute (vs. slower stamping or laser cutting).

• Ideal for large orders with consistent quality.
