Advanced FRP Composites

STRUCTURAL TECHNOLOGIES' lightweight V-Wrap™ Systems are supported by a team of specialists that help develop engineered solutions for strengthening of a variety of structural elements, including beams, columns and slabs.

V-Wrap™ FRP Composite Strengthening Systems

STRUCTURAL TECHNOLOGIES’ V-Wrap externally bonded carbon and glass fiber reinforced polymer (FRP) systems utilize lightweight, high-strength carbon fibers bonded with adhesive resins.

V-Wrap Systems™ are used to increase or restore load-carrying capacity to a variety of structures. Low profile,  flexible, and with very high strength, FRP can provide significant strength increase and is ideal for applications with limited access and/or complex geometries.

  • FRP Installation
    V-Wrap materials are ICC-ES approved, are environmentally friendly, and have UL-approved fire-resistant finishes available
    • Engineers can design and include in projects with confidence of plan check approval
    • ICC-ES approval provides long-term durability assessment that allows for 50-year 
    • Materials can be installed in active commercial, institutional and industrial environments, maximizing on-going operations for Owners
    • A variety of finishes including fire-resistant finishes allow engineers more options for use of V-Wrap materials
  • Carbon Fiber Plates
    V-Wrap offers significant ease and flexibility of installation over steel and other repair options
    • Can be installed on complex geometries in any orientation
    • Can be installed on-site, immediatiately, or long after structural member is put into place
    • Due to ease of installation it is often a lower overall cost alternative compared to steel and other materials
    • Ease of installation translates into faster schedule and provides cost saving advantages
    • Small construction footprint with no heavy equipment required provides advantages to Owner
  • Carbon Fiber Rod installation
    V-Wrap - increases shear, flexural, and axial strengths of structural members and improves ductility and seismic performance
    • Versatile. Can be utilized on a variety of structural elements including columns, beams, walls and slabs to restore and/or increase capacity and ductility
    • Lightweight. Material strengthens structural members with no impact on overall weight of structure
    • Thin. Low-profile system, typically 1/8” or less, allows for minimal impact on area where FRP being installed


V-Wrap™ Systems are engineered to meet a project's specific requirements. System components are selected to optimize application performance, and may include any combination of fabrics, laminates, resins, and coatings:
