Stainless Steel Spiral Duct Durable, Corrosion-Resistant HVAC Solutions

Apr 11 2025
Aktie:

stainless steel spiral duct

Did you know leaky HVAC ducts waste 25-40% of energy in commercial buildings? Traditional galvanized steel corrodes within 3-5 years in humid environments, forcing 73% of facility managers into costly replacements. Stainless steel spiral duct systems solve this crisis – and we’ve got the data to prove it.

Technical Superiority That Beats Spiral Welded Steel Pipe

Our 18-gauge 304L stainless steel spiral duct
s outperform standard spiral welded steel pipe with:

  • ✅ 2.5x corrosion resistance (ASTM B117 salt spray test)
  • ✅ 18% better airflow efficiency (SMACNA-certified)
  • ✅ 50% faster installation vs. rectangular ducts
Feature Our Product Competitors
Max Pressure +8" WG 5-6" WG
Warranty 15 Years 5-7 Years

Your Custom Solution in 3 Steps

Whether you need spiral steel pipe for pharmaceutical cleanrooms or chemical exhaust systems:

  1. Share your specs (diameter, gauge, length)
  2. Get engineered drawings in 48hrs
  3. Receive shipment in 2-3 weeks

Case Study: Food Processing Plant

Replaced carbon steel ducts every 4 years → Installed our stainless steel spiral ducts in 2020. Result: Zero corrosion issues, 68% lower maintenance costs.
