When to Use Steel Welded Bar Grating vs. Fiberglass Grating

When to use Steel vs. Fiberglass Grating (FRP)

Floor gratings can be manufactured using several different materials and various types of steel, and aluminum, also including fiberglass, Buyers must choose the material that will best perform the functions required of the grating, keeping in mind such constraints as strength, durability, corrosivity, conductivity, weight, and cost. Environmentally conscious buyers also consider the environmental impact of each material and its future recyclability.

In this article we’ll compare Steel Welded Bar Grating to Fiberglass Grating to guide you in your choice as you decide on the best suited grating for your facility. While fiberglass is appropriate for certain use cases, steel is often the safer, more economical, and more environmentally friendly choice.

Choosing between Steel Welded Bar Grating and Fiberglass

  • Steel is stronger, more durable, and more economical than fiberglass. It is required for grating that must withstand heavy loads, such as vehicular traffic. For elevated platforms and flooring, steel is the safer choice. Slip-resistant coatings and treads can be applied to steel grating for stairways and walkways. Steel grating can also offered in a serrated surface for more traction. Buyers who require corrosion resistance can choose stainless steel grating over carbon steel.
  • Steel is more environmentally friendly than fiberglass. Fiberglass is constructed from reinforced fiberglass plastic that releases VOCs (Volatile Organic Compounds), which, at high volumes, are harmful to human health and indoor air quality. As most fiberglass products are imported, carbon emissions are released to transport them overseas. Furthermore, while steel welded bar grating can be recycled, fiberglass cannot. In addition, since the integrity of fiberglass products can be compromised over time as the plastic is exposed to UV radiation, the grating is difficult to reuse or repurpose.
  • Fiberglass is lighter than steel, electrically non-conductive, and corrosion resistant. It is often used in the food, chemical, and wastewater processing industries because it doesn’t rust. Since it can withstand frequent submersion in water, fiberglass is a popular choice of grating for foot bridges, handrails, decks, and pond skimmers.

Steel with a Slip-Resistant Finish

At Interstate Gratings, we understand that some buyers may hesitate to select steel grating if they require the corrosion resistance and slip resistance that fiberglass is known for. Along with offering grating with a serrated surface, we offer slip resistant finishes in our line of steel products.

We offer two types of slip-resistant finishes for our steel gratings:

IG GritWeldTM for welded gratings and press-locked gratings. IG GritWeld™ is a thermally applied anti-skid surface. It offers the ultimate in traction for extreme environments.

Treaded checker plate nosing or GritWeldTM nosing for stairs. Treads along the nose of each stair (the edge that is stepped on) grip the undersoles of shoes to prevent slippage. GritWeldTM is a thermally applied anti-skid surface that provides extra grip for increased safety.

Interstate Gratings does offers a variety of fiberglass grating. Buyers who must adhere to weight restrictions or who require grating that do not conduct electricity should explore these options.

Top 5 Benefits Of Using Fiberglass Grating

Fiberglass grating is an increasingly popular material used by engineers. It has a wide range of applications from walkways to safety handrails and is known for its durability, heat resistance, and low maintenance. In this blog post, we’re going to explore the top five benefits of using fiberglass grating in engineering projects.

1. Fiberglass Grating Requires Little Effort to Maintain

Fiberglass grating is a low-maintenance material that can be easily cleaned with water and soap or diluted detergent. This makes it ideal for indoor applications such as meat packing facilities where food safety is paramount and for outdoor applications where the accumulation of dirt and dust is inevitable. Unlike other materials such as wood or metal, fiberglass gratings will not rot or corrode over time with exposure to the weather. It will continue to maintain structural integrity even when exposed to elements like salt water.

2. High Strength-to-Weight Ratio Compared to Traditional Materials

FRP is up to 70% lighter than steel while still providing excellent strength. This makes it perfect for areas where weight is a limiting factor but strength is a requirement. With fiberglass grating, engineers can create structures that are strong yet lightweight. Handling material that does not require heavy lifting also reduces the cost of labor (and transportation).

3. Fiberglass Grating has Very Good Thermal Resistance Properties

Fiberglass grating has excellent thermal resistance properties, providing a safer alternative to steel in environments where thermal conductivity would pose a risk. This makes it an optimal choice for industrial settings where temperatures may reach high levels on a regular basis. The material also has proven fire resistance properties, making it safer than other materials in the event of a fire emergency. Look for fiberglass grating that adheres to the American Society for Testing and Materials (ASTM) technical standards, including:

  • A flame spread of 25 or less as tested in accordance with ASTM E-84
  • Meets the self-extinguishing requirements of ASTM D-635

4. This Non-Conductive Material Makes Your Work Environment Safer

Unlike steel or aluminum, fiberglass grating does not conduct electricity. Its electrically-non-conductive properties make it a safer material for power stations or other environments where wiring systems or high voltage lines are nearby. Its non-conductive nature ensures that electrical currents do not travel through the material and injure workers or damage equipment.

5. The Cost Savings of Fiberglass Grating Solutions

Compared to other construction materials, such as metal, concrete, or steel, fiberglass grating is often more cost-effective due to its lower weight and ease of installation. This makes it a preferred option for budget-conscious engineers. Plus, it reduces or even eliminates the need for any heavy maintenance like sandblasting, scraping, and painting. With the selection of the right combination of resin, reinforcement, and manufacturing quality, FRP can have a much longer lifespan than other materials, increasing the ROI over the lifecycle of the structure.

Making Fiberglass Grating a Part of Your Infrastructure

FRP manufacturers offer fiberglass grating products that are an excellent choice for engineers looking for an affordable yet durable solution for their projects. Its low maintenance requirements make it ideal for outdoor applications while its high strength-to-weight ratio provides superior support without adding unnecessary weight to structures. Moreover, its thermal resistance and non-conductivity make it an excellent choice in areas with low or high temperatures or around live current systems. All these factors combined make fiberglass grating one of the most sought-after building materials in the engineering industry today!
