Pultruded Fiberglass Grating is high-strength grate that performs well in corrosive environments or where a lightweight grating is preferable. Fiberglass Grating pultrusions come in three categories: I-Shape bars, T-Shape bars, and High-Load bars for Heavy-Duty Applications. The bearing bars are interconnected with cross-rods every 6 inches. See the pultruded grating specs page for information on selecting the right grating for your application. See the video below to compare molded and pultruded grating.

FRP Grate Benefits: Corrosion resistant. High strength-to-weight ratio. Long service life. Fire retardant. Slip & impact resistant. Non-conductive. Superior ergonomics. Easy to fabricate. Easy to install. Attractive, clean finish.

Flame Retardant FRP Grating

Our pultruded grating is manufactured using a pultruded process using polyester or vinyl ester resin with flame retardant and ultraviolet (UV) inhibitor additives. A synthetic surface veil in the outermost layer covering the exterior surface.

6 Inch Cross Rods

The bearing bars are joined into panels by passing continuous length fiberglass pultruded cross rods through the web of each bearing bar. Each continuous fiberglass pultruded bar shaped section is wedged between the two cross rod spacers mechanically locking the notches in the cross rod spacers to the web of the bearing bars.

Continuous chemical bonding is achieved between the cross rod spacers and the bearing web and between the bar shaped wedge and the two cross rod spacers locking the entire panel together to create a panel that resists twist and prevents internal movement of the bearing bars.

Continuous Strand Mat

The FRP grating and stair treads shall be fabricated from bearing bars and cross rods manufactured by the pultrusion process. The glass fiber reinforcement for the bearing bars shall be a core of continuous glass strand rovings wrapped with continuous strand glass mat. A synthetic surface veil shall be the outermost layer covering the exterior surfaces.

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 structures and pultruded fiberglass grating are an essential part of FRP building structures that are “electronically transparent” and do not interfere with radio frequency transmissions.
