PULTRUDED FRP GRATING
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.
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.
Resins available for Pultruded Grating: Fire retardant isophalic polyester, isophalic polyester, vinyl ester, fire retardant vinyl ester, and phenolic. Our standard grating is ISO-Polyester, which provides superior performance in corrosive environments.
Pultruded Fiberglass Grating Specifications
All are available in polyester or vinyl ester for extremely corrosive environments.
FRP Applications for Your Industry
Our pultruded FRP gratings have applications in many industries, including:
food & beverage
oil & gas
metals & mining
pulp & paper
water & waste treatment, and
numerous architectural uses.
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.
