Composite floating roof


The Tanksystems DeckMaster GRP floating roof is a seamless, non-metallic full-contact floating roof. It’s gas-tight polypropylene honeycomb core is “sandwiched” between multiple layers of fiberglass utilizing modern high-grade Vinyl Ester resins designed to be resistant to most hydrocarbons in the petrochemical industry. The result is a smooth, seamless and virtually indestructible full-contact floating roof that also is corrosion free, thus necessitating little or no maintenance.


Key user benefits:

  • Maintenance-free — corrosion resistant, requires no painting, coating or spare parts
  • Minimal construction time & disruption — all materials fit through one 24” manway
  • Unsinkable — due to its multi-cell, gastight, leak-proof honeycomb core and the cured-in-place multi-layered fiberglass construction
  • Fully engineered and field-proven — 15+years, dozens of major oil & gas end-users
  • Maximizes tank capacity — low-profile cross-section increases working capacity
  • Virtually indestructible— aerospace composite sandwich construction

Key design features:

  • Full-contact — to eliminate vapors below the internal floating roof
  • Gas-tight — to accommodate both a mechanical shoe primary & secondary seals
  • High strenght — to withstand pigging, light-end slugs and turbulence from high fill rates
  • Seamless — single-piece construction qualifies for zero-deck-seam emissions per API
  • Chemically resistant — to all products typically stored in floating roof tanks
  • Fire retardant — tested by certified third-party specialist (Last Fire Group)
