SSTeelcoat® Coated Stainless Steel (SST)

Engineered for harsh chemical exhaust and built to install faster, cleaner, and safer than fiberglass.

When ductwork fails, operations stall, compliance is jeopardized, and teams are exposed to corrosive fumes. Conventional fiberglass systems degrade over time—forcing costly replacements and unplanned shutdowns.

SSTeelcoat® is engineered to end that cycle.

Why SSTeelcoat® Is Different

Stronger, safer, and easier to install than fiberglass.

SSTeelcoat® is engineered to solve the weaknesses of fiberglass and other conventional ductwork. Here’s how it sets the standard:

Materials Advantage: 304 or 316 stainless steel base for structural integrity; Halar® (ECTFE) coating applied via electrostatic powder process for superior chemical resistance.
Installation Advantage: Van Stone flanged connections install faster and safer than resin-wrapped fiberglass—no welding, no toxic resins, no weather delays. Easily modified in the field when layouts change.
Certified Performance: FM 4922 low-flame, low-smoke Class I material, CE marked, and backed by 50+ years of expertise since 1971.

Lifecycle & Compliance Advantages

Lower lifecycle cost with virtually maintenance-free operation.

Facilities that switch to SSTeelcoat® quickly see the long-term economic and safety benefits, with virtually maintenance-free operation:

Decades of service life reduce replacements and downtime.
Resists UV, impact, and aggressive chemical environments.
Non-absorptive walls mean no hazardous waste classification at end of life.
Can be disassembled and reused when layouts change.
Class 1 fire rating per ASTM E-84; NFPA 820 and FM 4922 compliant—often eliminating sprinklers and reducing insurance costs.
