FRP Grating – Molded or Pultruded?
There are two types of FRP Grating: Molded and Pultruded grating. Both types of Fiberglass Grating are strong, lightweight, and corrosion resistant, but there are some differences.
Molded Grating typically has a square mesh pattern similar to a checker board whereas PULTRUDED grating is made from a series of Parallel Bars.
The squares in the mesh pattern for Molded Grating are typically one and one-half inches on center. The top surface can be gritted as shown here, or a concave non-slip surface.
Other common Mesh patterns are 1 inch x 4 inch rectangular mesh and 1 x 6 as shown here on these molded stair treads.
The most popular panel sizes for molded grating are 4 feet by 12 feet, 4’ x 8’ and 3’ x 10’.
Pultruded Grating consists of a series of parallel bearing bars. The bearing bars typically have a ‘T’ or ‘I’ shaped profile. The closer the bearing bars are together, the stronger the grating.
The bearing bars are kept parallel with a series of cross-rods 6” apart that run at 90 degrees though the bearing bars.
Cross-rods are not intended to be applied in the span direction.
Pultruded grating can only support weight in the direction of the bearing bars.
The bearing bars in Pultruded Grating must traverse from support to support whereas Molded Grating is equally strong in both directions.
Molded Grating panels can be rotated 90 degrees with the same support characteristics.
Both Molded Grating and Pultruded Grating are available in one inch, inch and one-half and 2” deep panels.

Fiberglass 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. Molded Fiberglass Grating is an essential part of building structures that are “electronically transparent” and do not interfere with radio frequency transmissions.
