Fiberglass Grating

Fiberglass Grating, FRP Products & Accessories

Fiberglass reinforced plastic (FRP) grating is a molded or pultruded composite alternative to steel grating, built to resist corrosion, cut installation weight, and hold up in demanding industrial environments. Uniflex manufactures and supplies a full line of FRP grating, railing, ladders, structural shapes, and accessories for facilities where traditional metal products break down too fast.

Whether you’re installing industrial flooring, elevated walkways, access platforms, or cable tray systems, our fiberglass grating gives you a safer, longer-lasting alternative to steel, without the rust, the added weight, or the constant upkeep. From standard panels to fully customized solutions, our team works with you to match the right grating type, resin system, and configuration to your application.

Why Choose Fiberglass Reinforced Plastic (FRP)?

Facilities exposed to moisture, chemicals, or heavy foot and equipment traffic put steel grating through a lot. Over time, that means rust, pitting, and a maintenance schedule that never really ends.

FRP grating solves that problem at the material level. Because it’s built from fiberglass reinforcement set in a resin matrix rather than metal, it does not rust or corrode the way steel does, even in environments where moisture and chemical exposure are constant. It also weighs significantly less than steel, which means easier handling, faster installation, and lower long-term ownership costs.

Molded vs. Pultruded Grating: What’s the Difference?

Uniflex offers both molded and pultruded fiberglass grating, and the right choice depends on your load, span, and application requirements.

Molded Grating Pultruded Grating
Construction Continuous glass roving cast as a single interlocking panel Fiberglass rovings and mat pulled through a heated resin die to form structural bearing bars and cross bars
Best for General industrial flooring, walkways, and platforms where cost efficiency matters Applications with wider support spans and higher load-bearing requirements
Strength profile Excellent impact resistance and corrosion resistance Higher stiffness and load capacity per foot of span
Typical use case Standard flooring, mezzanines, general access areas Heavy-duty platforms, offshore structures, longer unsupported spans

Not sure which one fits your project? Our team can walk you through span tables and load requirements to help you specify the right product the first time.

Resin Systems: Matching Material to Environment

The resin system in your fiberglass grating determines how it performs against chemicals, fire exposure, and UV. Uniflex offers grating in multiple resin formulations, including:

  • Isophthalic polyester resin – An industrial-grade resin suited to environments with occasional chemical splash or spill exposure. Commonly specified with a flame spread rating of 25 or less.
  • Vinyl ester resin – Built for frequent, direct contact with harsh acidic or caustic chemicals, making it a common choice for chemical processing and wastewater treatment facilities.
  • Phenolic resin – Selected where fire resistance, low smoke, and low toxic fume emissions are critical, such as offshore platforms and other high-risk environments.
  • Fire-retardant formulations – Available for applications near sparking equipment, welding operations, or other elevated fire-risk areas.

All resin systems include UV inhibitors to protect against sun exposure and are available in a range of standard colors, with custom color matching available on request.

Designed for Safety

Slips, trips, and falls are a leading cause of workplace injury, and grating surface design plays a direct role in preventing them.

Uniflex fiberglass grating is manufactured with a slip-resistant surface that maintains traction across a wide range of conditions, including wet, oily, or icy environments. That makes it a reliable choice for walkways, platforms, and access routes where employees are moving through the space regularly.

Safety benefits include:

  • Slip-resistant walking surfaces in wet or contaminated conditions
  • Non-conductive properties, useful in electrical and utility applications
  • Consistent traction across production floors and outdoor platforms
  • Reduced injury risk compared with worn or corroded metal grating
  • Compliance-ready construction for OSHA walkway and platform requirements

Exceptional Corrosion Resistance

Corrosion is one of the most expensive problems in industrial infrastructure. Steel exposed to moisture, chemicals, or salt air corrodes over time, driving up repair and replacement costs.

Because FRP grating contains no exposed metal to rust, it holds up in environments where steel simply cannot, including chemical plants, wastewater treatment facilities, marine environments, and oil and gas operations. That resistance translates directly into fewer replacement cycles and a lower total cost of ownership over the life of your facility.

Lightweight Without Compromising Strength

Fiberglass grating typically weighs less than half of a comparable steel panel, without giving up load-bearing performance. That weight difference matters at every stage of a project:

  • Transportation – Lower freight costs and easier handling on site
  • Installation – Fewer crew members and less equipment needed to place panels
  • Structural load – Reduced dead load on supporting structures, which can matter on retrofit or upgrade projects

Industrial Applications and Commercial Environments

Uniflex fiberglass grating and FRP products are used across a wide range of industries where corrosion and slip resistance, durability, and safety are non-negotiable, including:

  • Oil and gas facilities
  • Chemical processing plants
  • Marine and offshore platforms
  • Mining operations
  • Wastewater and water treatment facilities
  • Commercial kitchens, food and beverage processing
  • Automotive manufacturing
  • Material handling and general industrial infrastructure

Common applications include:

  • Industrial flooring and mezzanines
  • Elevated walkways and access platforms
  • Stair treads and ladder systems
  • Cable tray systems
  • Handrail and guardrail systems
  • Maintenance platforms and catwalks

Standard and Custom FRP Solutions

Every facility has different load, span, chemical exposure, and layout requirements. Uniflex offers standard fiberglass grating panels ready for common applications, along with fully customized FRP solutions engineered around your specific project.

Our team has extensive experience and works directly with you to specify the right combination of grating type, resin system, mesh pattern, panel size, and surface finish, so you get a product built for your actual operating conditions rather than a generic fit.

A Cost-Effective Alternative to Traditional Materials

Upfront material cost is only part of the equation. Because FRP grating resists corrosion, requires less maintenance, and lasts longer in harsh environments, it often delivers a lower total cost of ownership than steel over the life of an installation, even when the initial investment is comparable.

Combined with lighter freight and faster installation, fiberglass grating is frequently the more economical choice once you factor in the full lifecycle of the product.
