There are many materials to choose from when it comes to industrial grating. Two of the most common choices are fiberglass gratings (fiberglass reinforced plastic also known as FRP) and metal gratings (usually steel or aluminum). While they both serve the same purpose, they have distinct characteristics that make them better suited for certain types of applications. Understanding their differences can help you make an informed decision when selecting grating for your project.

Fiberglass Gratings vs. Metal Grating Overview
Fiberglass grating and metal grating both have their own unique qualities that make them well-suited for certain applications. Its important to understand the differences between these two types of grates to determine which is right for your specific project. Lets look at fiberglass grating first.
Fiberglass Grating
Fiberglass reinforced plastic (FRP) grating is a great choice for both indoor and outdoor projects because it can withstand harsh weather conditions including salty air, UV exposure, and extreme temperatures as well as challenging chemical environments and health and safety issues, such as slip resistance. FRP grating requires very little maintenance. Dirt and other industrial substances can easily be washed away with just water and soap. Fiberglass gratings are lightweight yet strong, making the products easy to handle during installation, and also provide a safe and reliable walking surface.
Additionally, fiberglass grating is non-conductive, fire retardant, and corrosion resistant which are important considerations in certain industries or environments. It can easily be installed indoors or outdoors and only requires easily available hand tools such as a power saw to cut into the right size and shape for your application.

Metal Grating
Metal gratings are known for their strength and durability. Properly selected, they can hold up under heavy loads or traffic areas without any issue. However, steel grating can corrode very quickly in certain environments, and while galvanized steel and aluminum stand up to the elements somewhat better, ongoing maintenance can still be an issue. Metal grating has been widely used for many years; however, increases in commodity pricing for metals like steel and aluminum make this type of grating less appealing compared to options like FRP. FRP gratings tend to last longer and cost less over the lifetime of the grating.
Choosing the Right Option for Your Project
When deciding between fiberglass and metal grating for your next job consider where the grating will be used (indoors or outdoors), how much weight will be placed upon it (heavy foot traffic vs vehicles), the risks of slips and falls, how much maintenance you want to put into caring for the grating (corrosion resistance) etc... Ultimately, all of these elements should factor into your decision, so you can make the best choice possible for your specific needs.

Grating is a common structural element that can be used for various purposes, such as flooring, stair treads, platforms, walkways, drainage covers, and more. Grating can be made from different materials, such as steel, aluminum, or fiberglass. Each material has its own advantages and disadvantages, depending on the application and the environment. In this article, we will compare fiberglass grating and steel grating, two of the most popular choices for grating, and help you decide which one is better for your specific project.
What is Fiberglass Grating?
Fiberglass grating, also known as fiberglass reinforced plastic (FRP) grating, is a composite material that consists of fiberglass strands embedded in a resin matrix. Fiberglass grating can be molded into various shapes and sizes, and can have different surface patterns and colors. Fiberglass grating is lightweight, strong, corrosion-resistant, fire-retardant, non-conductive, and easy to install and maintain. Fiberglass grating is suitable for both indoor and outdoor applications, especially in harsh environments where metal grating may corrode or rust.
What is Steel Grating?
Steel grating is a type of metal grating that is made from steel bars or wires welded or locked together at right angles. Steel grating can have different load-bearing capacities and surface treatments, such as galvanized, painted, or powder-coated. Steel grating is durable, rigid, economical, and recyclable. Steel grating can withstand heavy loads and high temperatures, making it ideal for industrial and commercial applications. However, steel grating can also be susceptible to corrosion, rusting, and electrical or heat conduction.
Comparison of Fiberglass Grating and Steel Grating
To compare fiberglass grating and steel grating, we need to consider several factors, such as strength, weight, cost, maintenance, safety, and environmental impact. Here is a summary of the main differences between the two types of grating:
Factor
Fiberglass Grating
Steel Grating
Strength
High strength-to-weight ratio; flexible and resilient; can withstand impact and fatigue
High load-bearing capacity; rigid and stable; can withstand high temperatures
Weight
Lightweight; easy to handle and transport; reduces structural support requirements
Heavy; requires more labor and equipment; increases structural support requirements
Cost
Higher initial cost; lower life-cycle cost; lasts longer and requires less maintenance
Lower initial cost; higher life-cycle cost; may need frequent replacement and maintenance
Maintenance
Low maintenance; corrosion-resistant; easy to clean with water and soap
High maintenance; prone to corrosion and rusting; may need painting or coating
Safety
Non-conductive; fire-retardant; slip-resistant; reduces noise and vibration
Conductive; may need fire-proofing; may need anti-slip coating or serration; may cause noise and vibration
Environmental Impact
Non-recyclable; releases VOCs during production; may degrade under UV exposure
Recyclable; consumes more energy and resources during production; emits greenhouse gases during transportation
Conclusion
As we can see from the comparison table above, fiberglass grating and steel grating have their own pros and cons. There is no definitive answer to which one is better for your application. It depends on your specific needs and preferences. You should consider the following questions before making your decision:
Where will the grating be used? Indoor or outdoor? Wet or dry? Hot or cold?
How much weight will the grating support? Light or heavy? Static or dynamic?
How much are you willing to spend? Initial or long-term? Installation or maintenance?
How important are safety and performance? Corrosion or fire? Slip or shock?
How do you care about the environment? Recyclability or sustainability? Emissions or VOCs?
By answering these questions, you can narrow down your options and choose the best type of grating for your project. If you need more information or assistance, please feel free to contact me.
