National Grating fiberglass Square mesh panels are ideal for decking, walkway, and flooring applications in corrosive environments.

1.5″ Square Mesh Grating is the long-lasting solution for rugged applications. Steel and aluminum grating have considerable down-sides; they corrode, wear down quickly, cause maintenance headaches and downtimes, and are costly to install.

National Grating high-strength molded FRP grating can be designed and used like traditional metal grates, but with all the many benefits of fiberglass. 1-1/2″ x 1-1/2″ Square FRP grating is especially useful for replacing steel grating or aluminum grating in corrosive environments or where other types of gratings require frequent replacements. For smaller mesh sizes check out our mini-mesh Fiberglass Grating.

Resin Systems
National Grating Molded Fiberglass is available in two standard resin systems. Each providing different levels of corrosion protection. Both resin systems meet Class 1 Flame Spread Rating per ASTM E-84 test standards.

Polyester: A premium-grade isophthalic polyester resin system that provides excellent corrosion protection. Standard colors: Dark Gray, Light Gray, Yellow, and Green

Vinyl ester: A chemically resistant system that provides the highest level of corrosion protection. Standard colors: Yellow, Dark Gray, and Orange

Fiberglass Grating Walkways

Fiberglass Grating Walkways

When designing walkways in corrosive environments such as chemical plants and waste-water treatment plants, fiberglass grating walkways are a long-lasting, cost-effective alternative to steel or aluminium.

At National Grating we specialize in all types of molded and pultruded FRP grating. Molded grating walkways are typically a lower price than pultruded walkways. The most common molded grating panel sizes are 3 x 10, 4 x 8 and 4 x 12 (feet).

Call us at 1-877-984-5421 and we will help you select the panels sizes with the best yield depending on the length and width of the walkway.

FRP Walkway —Molded Grating Walkway

This is a molded fiberglass grating walkway.

Molded fiberglass grating walkways provide durable, cost-effective service in tough environments.

Molded grating panels are 1″, 1-12″, or 2″ thick. When selecting your molded fiberglass grating walkways, check the weight-bearing specifications and span between the supports in the structure holding up the walkway. The farther the supports are apart underneath the grating, the stronger the grating required. Most of the molded grating we have in stock is Dark Gray and Yellow. We also have light gray, green, and orange for some profiles.

Check out our Grating Selection Chart to find the grating that is right for your application.

Molded grating consists of a series of 1.5″ squares in a checkerboard pattern. If you need more surface area for your walkway, or you need a stronger grating to span a wider walkway, you may need pultruded fiberglass grating walkways.

Fiberglass Walkway
—Pultruded Grating Walkway

pultruded fiberglass grating walkways - in stock and ready to ship

Pultruded fiberglass grating walkways provide excellent service for many outdoor applications, such as this marina.

Pultruded Grating consists of a series of parallel bearing bars separated by cross-rods spaced every 6″. Care must be taken when choosing pultruded fiberglass grating walkways to assess the weight-bearing capacity of the material. Unlike molded grating, pultruded grating is only strong in the direction of the bearing bars. The cross-rods do not provide any support whatsoever. They are only used to keep the bearing bars parallel to each other.

Pulruded Grating
—Putruded Grating with Yellow Nosing

FRP Stair treads typically have a nosing on the leading edge to strength the stair tread and minimize any tripping hazard. You will also see the nosing at the beginning of the walkway as well.

This highly visible transition is an important safety feature. Ask our service reps about the yellow nosing options available for your pultruded fiberglass grating.

You can either order our FRP grating walkways cut to size at our warehouse, or you can order full panels and cut to size yourself. Check out our video on How to Cut FRP Grating.

This product meets required frp specs Fiberglass Walkways and Radio Frequency Transparency

In today’s connected world, we depend on cellular telephone signals, Wi-Fi networks and over the air radio and television signals. Wi-Fi and Bluetooth connectivity are essential to on-site work environments. Steel structures significantly disrupt these signals. Fiberglass grating walkways are an essential part of FRP building structures that are “electronically transparent” and do not interfere with radio frequency transmissions.
