Steel Alternatives: Learn about Heavy Duty FRP Grating

The need to control construction costs without sacrificing safety and durability has made fiberglass reinforced plastic (FRP) grating a popular option to replace traditional materials like steel, aluminum, and wood. FRP grating comes in several varieties, each with its own unique characteristics. However, all Fibergrate FRP products share some characteristics:

• Lightweight with low installation costs
• Corrosion resistant, fire retardant, and non-conductive
• High strength-to-weight ratio with a long service life
  

Understanding What Heavy Duty FRP Grating Load Ratings Mean

In the context of FRP grating, a load rating is a measure of the maximum weight or load that a material or structure can support without failure or deformation. Grating with a higher load rating can handle more weight and is suitable for applications with heavy loads or vehicular traffic.  

Here’s a look at the load ratings of Fibergrate high load grating products:

Load ratings are crucial for choosing the right grating for your project because they ensure safety and performance. In applications designed to support turning traffic, a higher load rating is needed because turning movements place additional stress on the grating compared to straight-line traffic. Turning creates a differential in the load distribution, causing higher concentrated forces on the grating during the turning process.

As a result, the grating must be able to withstand these localized higher loads without experiencing deformation or failure. Heavy duty FRP grating, engineered to carry forklift and other vehicular loads that regular FRP grating may not support, is a suitable option for areas with turning traffic and other high-load applications. In fact, only Fibergrate produces a high load capacity (HLC) molded grating product that possesses the required durability to withstand vehicular turning traffic.

Comparing Heavy Duty FRP Grating with Steel for Load Rating

Steel has long been the go-to material for heavy-duty applications due to its high load-bearing capacity. However, heavy duty FRP grating has emerged as a viable alternative to steel, offering several advantages:

• Lightweight nature compared to steel, making installation and transportation easier and more cost-effective.
• Excellent corrosion resistance, making it ideal for outdoor and corrosive environments where steel may degrade over time.
• Non-conductive properties make it a safer option for projects that involve electrical equipment or hazardous environments.

Heavy duty FRP grating can handle substantial loads while still being relatively lightweight and corrosion-resistant, making it a superior choice for various applications where traditional steel grating would be less practical.

Applications for Heavy Duty FRP Grating

A few examples of where heavy duty fiberglass grating makes an excellent choice include:

• Flooring
• Storage Areas
• Ramps
• Loading areas
• Trenches (both with open grating or solid tops)

Quick Example: In one installation, our client used our 2” deep, 2” square mesh molded grating with a grit surface in the Los Angeles Light Rail system’s maintenance platform. In this facility, corrosion resistance, long life, and low maintenance were key, and our high load grating was up to the challenge. 

What Makes Fibergrate High Load Grating Stand Out

Fibergrate high load capacity grating is a standout product engineered to carry forklift and other vehicular loads. Combining the strengths of traditional FRP (high strength, corrosion resistance, fire retardancy, and low maintenance), these products offer a reliable choice for demanding applications. 

With at least 48% open area for drainage and the option for a solid top when needed, our high load grating provides versatile solutions for various projects in two primary product categories:

1. Molded High Load Capacity (HLC) Grating: 

• • Unique one-piece construction withstands vehicular turning loads
  • Available in 1-1/2” and 2” depths
  • Used in storage areas, trench covers, flooring, ramps, & loading areas
  • Corrosion Resistant

2. Pultruded High Load (HI) Grating

• • High unidirectional strength 
  • Engineered to withstand forklift & tractor trailer loads
  • Available in 1”, 1-1/2”, 2”, 2-1/2”, & 3” depths
  • Used for trench covers, flooring, ramps, & loading areas
  • Corrosion Resistant

When it comes to projects that require high load capacity, heavy duty FRP grating from Fibergrate offers an excellent alternative to traditional materials like steel. Its lightweight nature, corrosion resistance, and high strength make it an attractive choice for various applications.
