Fiberglass Grating Catwalks

When designing Catwalks 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 aluminum.

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

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

Molded grating panels are 1″, 1-12″, or 2″ thick. 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 see which type of grating will best fit your application.

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

Pultruded Grating consists of a series of parallel bearing bars separated by cross-rods spaced every 6″. 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.

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 Catwalk as well.

You can either order our FRP grating 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.
