Fiberglass Structurals

frp-structrual Fiberglass Structurals & Shapes

FRP structural shapes are the best alternative to wood or steel. They are lightweight compared to other building materials. All of our FRP products won’t rust, mildew, or rot and are non-conductive. We carry a vast inventory of fiberglass grating and structural shapes. We also have complete handrail systems, ladder systems, stair treads, and fabrication capabilities.

Fiberglass structural shapes are used to create what we call structurals. Fiberglass reinforced plastic structurals are becoming an increasingly popular choice for industrial installations that require strength, durability and resistance to humidity, corrosion and aging. Thanks to the flexible manufacturing methods we apply to make our FRP structural systems, we can offer you an extremely wide range of standard products as well as custom solutions.

Our FRP systems are OSHA-compliant and can be used across all types of industries. With a choice of colors, styles and finishes, you can easily integrate fiberglass reinforced plastic structurals to an existing facility or installation or have us create a new system from the ground up. Our team has experience offering intelligent solutions for your industrial grating, guarding, passageway and climbing requirements and can work with your plans, blueprints and drawings to create an optimized FRP system.

Marco Specialty Steel offers all standard fiberglass structural shapes used for structural projects. They are manufactured in both vinyl ester (standard color is beige) and polyester (standard color is dark gray). Embedment angles are only manufactured in vinyl ester and standard in dark gray to compliment the color of concrete.

Benefits of Fiberglass Structural Shapes

  • Will not Rot, Rust or Corrode: Our fiberglass reinforced structural shapes offer the strength of traditional building materials with a longer life cycle.
  • Will not Shrink, Swell, Warp or Bow: Hot or cold, wet or dry, our FRP structural members remain dimensionally stable.
  • Easy, Quick Installation: Fiberglass structural shapes can be cut, drilled and assembled using standard tools.
  • Built for Safety: FRP grating and decking are available with safe, nonslip surfaces. This is especially useful to prevent slips and falls in wet or oily conditions. As well as excellent cushioning to support workers with less strain and fatigue.
  • Options and Applications: Options include NSF certification, UV inhibitors, fire-retardant resin and more.

Grating Systems and Stair Treads

Choose our FRP structural grating systems and stair treads for their strength and durability. We offer a range of styles and designs that suit your application. Choose from:

  • Open rectangular grid designs that allow a maximum of debris to pass (ideal for outdoor installations)
  • Smooth, rounded openings for minimal chance of snagging and tearing bags and containers
  • Multiple grid patterns that allow for clear viewing (to see if anyone is on or below the stairs/walkway)
  • Textured surfaces that increase adherence for applications that might get wet or dirty
  • High-strength designs for floor gratings that need to withstand the passage of lift trucks and vehicles

We design and build our FRP systems to meet OSHA compliance so you don’t have to worry about possible regulation issues. Thanks to the inert and resistant nature of fiberglass reinforced plastic, our grating systems and stair treads are suitable for use in harsh environments that include heat and cold, moisture and chemical exposure.
