STRUCTO-CRETE® Brand Structural Panels

Noncombustible concrete subfloor panels offer fast installation, structural stability, and 1- and 2-hour fire-rated assemblies.



The only noncombustible cementitious structural panel manufactured in the United States.

STRUCTO-CRETE® Brand Structural Panels are noncombustible, inorganic, and mold-, moisture-, and termite-resistant. The panels are cured in-factory and dimensionally stable for use in subfloor assemblies for many floor finishes. STRUCTO-CRETE® Brand Structural Panels meet the full criteria of ASTM E136 for use in all types of noncombustible construction. Numerous 1-, 2- and 3-hour fire designs are available for modular, panelized, and conventionally constructed buildings to meet virtually any application. The panels are easily cut with standard framing tools, rapidly applied using mechanical fasteners, and require no adhesive for installation.

    1. Panels can be custom cut
    2. Can be requested to have 10 panels per pallet.
    3. Can also be Square Edge if requested.
  • Are all panels equivalent to STRUCTO-CRETE® Panels?

    A: No. STRUCTO-CRETE® Panels are the only UL-certified noncombustible cementitious panel in North America. STRUCTO-CRETE® Panels offer the simplest 2-hour floor/ceiling fire assembly which saves time and money.

  • Will STRUCTO-CRETE® Panels meet code requirements?

    A: STRUCTO-CRETE® Panels are compliant with the 2012, 2015 and 2018 IBC.

The panels are certified noncombustible by Underwriters Laboratories Inc (UL) in accordance with the current version of ASTM E136. The panels take the place of traditional poured concrete and metal deck in cold-formed steel framing, STRUCTO-CRETE® Panels are a lighter and easier solution, requiring only the basic carpentry tools for installation.

  • Is there a UL fire-rated system with STRUCTO-CRETE® Panels?

    A. Yes. We have the simplest 2-hour assemblies G556 and H505 with one layer of drywall (ULIX). We have the most comprehensive testing database of any panel for different assemblies, which can be found at:

  • Can STRUCTO-CRETE® Panels be left bare?

    A: No, must be covered and protected from traffic wear.

  • Who can install STRUCTO-CRETE® Panels?

    A: The carpenter typically leads the installation of STRUCTO-CRETE® Panels, which allows you to eliminate the many trades needed to pour concrete.

  • What are the common applications for STRUCTO-CRETE® Panels?

    A: STRUCTO-CRETE® Brand Structural Panels are for subfloor applications, typically used in midrise buildings, health facilities, theaters, hotels, residential buildings and homes, multipurpose midrise buildings, panelized construction or in simple platforms or mezzanines.

    A: Refer to our repair manual that takes you through the steps of repairing damages of square holes max. 6" by 6" or round holes max. 6" in diameter.

  • What are the benefits of using STRUCTO-CRETE® Panels vs. poured concrete?

    STRUCTO-CRETE® Panels are:

    • Lighter – less weight, less overall structural material
    • Faster – no wait for curing, fewer trades (carpenters can install STRUCTO-CRETE® Panels), greater schedule flexibility, faster time to open
    • Lower risk – no moisture uncertainty, cured so there is no excessive free water
    • Lower total installed cost – fewer trades, less material, less equipment, faster time to open
  • How do we achieve meaningful time savings on a project using STRUCTO-CRETE® Panels?

    A: STRUCTO-CRETE® Panels are easy to install (lay, fasten, finish), and only requires a single trade. Unlike poured concrete, it can be installed in any weather, and it eliminates the wait to cure and dry. Other trades (e.g. mechanical and electrical) can begin work sooner. Schedule compression leads to lower project cost and faster time to open.

  • What floor coverings can be used over STRUCTO-CRETE® Panels?

    A: A variety of floor coverings can be used but an engineered underlayment is recommended over the panel except with carpet and pad.
