Fiberglass (FRP) Tanks — Built for Tough Environments, Engineered to Last.

Leak-proof storage. Certified standards. Lightweight strength. James Riggins specifies ASTM D3299 filament-wound FRP with the right resin system & corrosion barrier to stop wicking, resist chemical attack, and survive seismic loads.

The James Factor: FRP That Doesn’t Blister, Weep, or Fail Audits

Failures come from wrong resin/liner and inconsistent lay-up. James specifies filament winding for hoop strength and a C-Veil (or synthetic veil) corrosion barrier matched to your MSDS and temperature.

Factor
Generic Import / Spray-Up
Riggins Spec (ASTM D3299)
Construction Method
Spray-up/hand lay-up; variable thickness
Filament Wound; machine precision, high hoop strength
Corrosion Barrier
Random resin; risk of wicking/weeping
C-Veil resin-rich interior for chemical attack
Resin Selection
One-size polyester
Vinyl ester / isophthalic matched to duty
Seismic & Wind
Flat bottoms; weak tie-downs
Engineered lug patterns; stamped calcs available
Maintenance
Re-coats; frequent inspection
UV gelcoat; low maintenance exterior
Documentation
Basic cut sheets
Submittals, torque specs, startup; audit-ready
Total Impact
Leak-proof, compliant, long-life installs
James’ Pro-Tip: Don’t just ask for “FRP.” Specify the resin family (vinyl ester for many acids), the veil/barrier, required temperature, and seismic/wind criteria. That’s how you avoid blistering and warranty fights.

FRP Configurations: Built for Your Footprint

Filament-wound FRP tank with optional double-wall containment.

Vertical Flat / Cone Bottom: Industrial standard with massive hoop strength. Open or closed tops; manways and nozzles to spec.

Double-Wall FRP: For hazardous chemicals where berms are impractical. Interstitial monitoring ports available.

Underground Wastewater: Non-reactive to sewer gases (H2S); engineered for soil loads.

Fire Water / Potable Dual-Use: One corrosion-immune vessel for NSF-61 water and fire reserves.

Need pumps or controls, too? We integrate Transfer Pumps and Feed Skids directly at the outlet.

Custom Fabrication & Horizontal Tanks

For height-restricted rooms or mobile systems, we spec horizontal tanks with domed/dished ends and engineered cradles. Ideal for agriculture and skid-mounted duty.

  • Domed/Dished Ends for strength
  • Internal Baffles for surge control
  • Custom nozzles, manways, ladders & platforms
Custom fabricated FRP tank with ladder, platform, and seismic anchors.

Applications: Where FRP Beats Steel & Poly

Engineered resin/veil systems deliver durability where metals pit and basic plastics creep or craze.

FRP Tank FAQ

Why choose FRP over stainless steel?

FRP is immune to electrochemical corrosion, installs faster (lighter weight), and resists chloride attack that pits many stainless grades.

Filament wound vs. hand lay-up?

Filament wound (ASTM D3299) uses continuous glass strands and controlled winding for structural hoop strength. Hand lay-up (ASTM 4097) is labor-intensive and used for certain geometries/liners.

Potable water and fire reserve in one tank?

Yes—when specified with NSF/ANSI 61 compliant resins and the right gelcoat. We’ll confirm resin system and labeling at submittal.

What about UV exposure?

We specify a UV-stabilized gelcoat to prevent fiber bloom and preserve appearance and integrity for decades outdoors.
