After 50 years of experience producing fiberglass reinforced polymer panels for the corrosion and industrial markets, Resolite is now drawing on that knowledge to provide a deck product with a special blend of corrosion and moisture resistant vinyl ester resin and fiberglass reinforcement. Resolite Tred-Safe™ DECK is an industrial construction unit that integrates corrosion resistance and high strength in a lightweight assembly.

Resolite Tred-Safe™ DECK is the smart choice for the highly corrosive environments found in pulp and paper mills, galvanizing plants, salt operations, metal processing and chemical plants. Tred-Safe™ DECK is the ideal replacement for old wood decks, spalling concrete channel slabs or other deteriorated systems. It can be used either as a support for a built-up or single ply roofing system, or as a form for poured reinforced concrete slabs.

The unique combination of fiberglass reinforcement built into Tred-Safe™ DECK provides an exceptionally strong unit. Building owners and installers can be assured that Tred-Safe™ DECK provides a safe working platform and can be used in many of the same applications as light gauge metal roof deck.

Features and Benefits


  • 25" Flame spread rating
    Passed the ASTM E 84 Steiner Tunnel Test and achieved a 25" flame spread rating.
  • Corrosion resistant
    Produced with a high quality halogenated vinyl ester resin.
  • Embossed surface
    The interior (exposed) surface is embossed creating a resin rich surface to improve performance.
  • Multiple glass reinforcements
    Tred-Safe DECK utilizes a combination of glass reinforcement including bidirectional continuous strand woven and chopped strand glass. This multi-layered glass fiber reinforcement assures installers and building owners that Tred-Safe DECK provides a safe working platform.
  • Outstanding performance
    Backed by over 50 years of case history in the corrosion and industrial market.

  • 1 Resolite advises that the numerical flame spread classification is not intended to reflect hazards presented by this or any other material under actual fire conditions.
