Since Pultruded gratings are manufactured by pulling and assembling load bars and positioning those bars as needed to create panels as required, in addition to our standard panel sizes, we are able to reduce the waste material by manufacturing custom panels to size. We pultrude load bar lengths as required and assemble panels to required widths. There is no need to manufacture a full panel and waste material. In addition, we are able to custom manufacture panels of various sizes and standard styles.

Pultruded fiberglass Grating, I-beam Garting
Product Description
FRP I Beam Bar Grating Fiberglass Reinforced Plastics Pultruded Grating GRP Pultrusion Grating
Pultruded FRP Gratings are assembled from pultruded shapes. These shapes (I-Bars, T-Bars, etc.) are manufactured by pulling fiberglass rovings and mats through guides, then into a resin bath, then wrapped with a surfacing veil, then finally pulled through a heated die to form the desired bar shape. Once the bars are pulled, they are drilled for crossrods, then assembled by installing the crossrods spaced on 3” or 6” centers (depending on the grating type). These crossrods, that lock the bars into place, are then bonded with epoxy to ensure the bars will not move.

FRP I Beam Bar Grating Fiberglass Reinforced Plastics Pultruded Grating GRP Pultrusion Grating
Pultruded Fiberglass Grating Process:
During the putrusion process, a caterpilla-like machine grips the raw materials and "pulls" them through a series of steps until the finished profiles reach the cut-off saw.
Fiberglass roving and mat is pulled through guides on an automated and continuous cycle. Next, the profile receives a resin bath. Then, it is wrapped with a surface veil before being pulled through a heated die. The final task is to assemble the load bearing bars, groove and notch rod. The bearing bars are drilled on centers along the length and the cross rods are inserted and secured with epoxy perpendicularly to the bearing bar to form panels.
The reason fiberglass grating is so strong is that the material has a high glass-to-resin ratio as previously mentioned. This increases the load rating and the stiffness of the grating, making it highly valuable in industrial settings.
This type of FRP grating offers builders a wide variety of panel sizes, and flexibility because it is assembled and not molded.This helps to reduce waste, or scraps of FRP in comparison to the molded fiberglass grating process.

Surface types:
Concave Surface (meniscus profile) – This is how the grating comes naturally out of the mold. The raised edges form a lip which
offers slip resistance.
Grit Surface – Excellent slip resistant surface.
Standard Grit - Most commonly used.
Smooth Surface – Great for Bar Screens at Wastewater Treatment plants or Architectural applications.

2. Strength: 2 to 3 times stronger than molded grating, suitable for wide support span, carry great load bearing.
3. Impact resistance: The 65% glass to 35% resin ratio of pultruded grating provides twice the stiffness of molded grating, high
ultimate strength prevents impact damage.
