Ductwork

The Hidden Costs of Standard Ductwork in Corrosive Environments

Standard galvanized ductwork wasn’t designed for your chemical streams. Acid vapors eat through joints, corrosion creates leaks, and emergency repairs shut down operations when you can’t afford downtime.

Viron’s corrosion-resistant ductwork eliminates these risks before they impact your bottom line. Three proven material systems—SSTeelcoat® coated stainless steel, FRP, and thermoplastics—deliver long service life with virtually maintenance-free operation across semiconductor fabs, chemical plants, wastewater facilities, and metal finishing operations.

Built to move air safely from source to treatment, no matter how aggressive your chemistry.

SSTeelcoat® Coated Stainless Steel
Maximum Durability

When your facility can't tolerate ductwork failures, SSTeelcoat® delivers unmatched chemical resistance and fire safety compliance.

  • Class 1 Fire Rated (ASTM E-84) with low flame and smoke development
  • FM 4922 & NFPA 820 compliant - often eliminates costly sprinkler systems
  • Handles 300°F continuous operation plus thermal cycling
  • Bolt-together construction speeds installation and allows reconfiguration
  • Non-hazardous waste classification when disposal is eventually needed
Ideal For:
Semiconductor tool exhaust, high-temperature processes, occupied spaces requiring fire safety compliance

  • UV-resistant formulations for outdoor installations
  • Custom fabrication from 4" to 120"+ diameters
  • Welded joint construction ensures leak-tight performance
  • Cost-effective choice for budget-conscious projects
Ideal For:
Acid waste systems, laboratory exhaust, selective chemical processes

Frequently Asked Questions

How do I select the right ductwork material for my application?

We review your specific chemicals, operating temperature, pressure requirements, and fire safety codes to recommend the best material for performance and cost-effectiveness.

What pressure ratings can your ductwork handle?

It depends on the material. Thermoplastic systems typically handle moderate pressures per SMACNA standards, while FRP and SSTeelcoat® systems can be built for higher duty cycles with customized wall thickness and reinforcement.

Do you provide installation drawings and technical documentation?

Yes. Every project includes fabrication drawings, installation details, material certificates, and dimensional specifications. CAD files are available in formats compatible with major engineering platforms.

Can ductwork be modified or expanded in the field?

SSTeelcoat® systems allow easy field modifications due to bolted construction. FRP systems can be modified using compatible resins and techniques. Thermoplastic systems allow limited adjustments with proper welding procedures.
