When durability, corrosion resistance, and safety are top priorities in industrial flooring, walkways, or platforms, fiberglass grating is often the go-to choice. Whether used in marine environments, wastewater treatment plants, or chemical facilities, fiberglass offers a long-lasting and lightweight solution compared to steel. In this guide, we’ll break down what makes molded fiberglass grating so effective, the different types available, and how to identify reliable fiberglass grating suppliers for your project or resale needs.

 

What Is Fiberglass Grating?

 

Fiberglass grating is a composite material made from a matrix of resin reinforced with glass fibers. It's formed into grid-like panels used in areas where moisture, chemicals, or heavy loads are present.

 

Unlike traditional metal grating, fiberglass won’t rust or corrode, making it ideal for harsh and corrosive environments.

 

Types of Fiberglass Grating

 

The two main categories of fiberglass grating are:

1. Molded Fiberglass Grating

Made by pouring resin and fiberglass into a mold.

Strong in both directions (bi-directional strength).

Ideal for applications with heavy pedestrian traffic or corrosive exposure.

Offers slip resistance due to its gritty surface.

Commonly used in chemical plants, offshore platforms, and water treatment facilities.

 

2. Pultruded Fiberglass Grating

Manufactured by pulling fiberglass strands through a resin bath and then through a heated die.

Stronger in one direction.

Best for long-span applications and heavy loads.

Typically used in platforms, mezzanines, and trenches.

While molded fiberglass grating is more common in general-purpose settings due to its flexibility and slip resistance, both types have their place depending on structural needs.

 

Advantages of Using Fiberglass Grating

 

✔ Corrosion Resistant – Perfect for chemical plants, wastewater areas, or saltwater exposure.
✔ Non-Conductive – Safe in electrical applications.
✔ Slip-Resistant Surface – Reduces accidents in wet or oily conditions.
✔ Lightweight Yet Strong – Easier to transport and install than steel grating.
✔ Low Maintenance – No painting, no rust, and long service life.
✔ Fire Retardant – Many resins are available with fire-resistant properties.

 

Common Applications

 

Fiberglass grating is found across a variety of industries:

Oil & Gas (offshore platforms)

Water & Wastewater Treatment Plants

Food & Beverage Processing

Marine Docks and Ship Decks

Chemical Facilities

Cooling Towers

Public Infrastructure (walkways, trench covers)

 

How to Choose the Right Fiberglass Grating Supplier

 

Not all fiberglass grating suppliers are created equal. Here’s how to evaluate a supplier before placing your order:

Material Quality

Look for suppliers who use premium resins like vinyl ester, polyester, or phenolic for superior corrosion and fire resistance.

Certifications

Does the product meet industry standards like ASTM, ISO, or OSHA? Certification ensures consistency and performance.

Customization

Top suppliers offer custom panel sizes, colors, resin types, and surface coatings. Some even provide CNC-cutting or in-house fabrication.

Stock Availability

For urgent jobs, having access to in-stock sizes and fast shipping options is crucial.

Technical Support

Reputable suppliers will help you choose between molded fiberglass grating and pultruded types based on your structural requirements.

Reviews or Project Case Studies

A track record of successful deliveries to similar industries builds trust and reduces the risk of defects or delivery issues.

What About Pricing?

Pricing for fiberglass grating depends on several variables:

Factor	Impact on Price
Resin Type (e.g., VE, PE)	Vinyl ester is more expensive than polyester
Grating Thickness	Thicker panels = higher cost
Mesh Size & Load Rating	Heavy-duty ratings cost more
Quantity Ordered	Bulk purchases reduce unit cost
Customization	Extra cost for cut sizes or colors

 

Typical prices range from $25 to $60 per square meter, depending on specs and order volume.

 

Fiberglass grating is a top-performing material in corrosive, wet, and heavy-duty environments. For most general industrial uses, molded fiberglass grating provides excellent durability, slip resistance, and long-term cost savings. When sourcing from fiberglass grating suppliers, prioritize product quality, certification, and reliability just as much as price. A good supplier will not only deliver the panels you need—but also the support to help you make the right technical choices.

 

Fiberglass Grating FAQs

 

1. What’s the difference between molded and pultruded fiberglass grating?

 

Molded is better for corrosion and slip resistance; pultruded is stronger for long spans or heavy loads.

 

2. Is fiberglass grating safe to walk on in wet conditions?

 

Yes. Molded grating typically has a slip-resistant surface designed for safe footing in wet or oily environments.

 

3. How long does fiberglass grating last?

 

With proper installation, fiberglass grating can last 20+ years, even in corrosive settings.

 

4. Can I cut fiberglass grating myself?

 

Yes, but it's recommended to use proper tools (diamond blade) and wear protection. Many suppliers offer pre-cut options.

 

5. Is fiberglass grating fire retardant?

 

Yes, if made with fire-resistant resin systems like vinyl ester. Always confirm this with your supplier.
