Fiberglass Grating Heavy Duty
Introdução ao desempenho do produto
Heavy Duty Fiberglass Grating is a high-strength, molded or pultruded fiberglass reinforced plastic (FRP) grating designed to withstand substantial loads in extreme industrial environments. Unlike standard FRP grating, heavy-duty grating features thicker bearing bars, wider panel depths, e reinforced load capacity, making it suitable for areas where forklifts, heavy machinery, or vehicular traffic may be present.
Manufactured using high-performance resins—such as vinyl ester, isophthalic polyester, ou phenolic—this grating offers outstanding resistance to corrosion, chemical exposure, moisture, and UV degradation, ensuring long-term durability even in highly aggressive settings like chemical plants, pulp and paper mills, marine docks, or mining operations.
Heavy duty FRP grating is available in both molded e pultruded types. Molded heavy-duty grating provides multi-directional strength and excellent impact resistance, while pultruded heavy-duty grating offers superior load-bearing performance in the span direction, ideal for trench covers, driveways, and load-bearing platforms.
One of the standout features is its high strength-to-weight ratio. Compared to steel grating, it offers comparable or superior strength with significantly lower weight, resulting in easier handling, reduced installation labor, and lower transport costs. Additionally, it does not conduct electricity, making it ideal for electrical safety zones.
Heavy-duty fiberglass grating is typically available with a gritted anti-slip surface, enhancing safety in slippery conditions. It also requires minimal maintenance since it won't rust, rot, or need repainting, reducing total life cycle costs.
Common thicknesses range from 1.5" to 2.5" and can be custom-designed for specific loading conditions, including H-20 or forklift-rated traffic.
In demanding industrial or commercial applications where strength, safety, and durability are critical, heavy duty fiberglass grating is a superior alternative to steel and concrete-based flooring systems.

Perguntas frequentes
P:
What makes fiberglass grating “heavy duty”?
A :
Heavy duty fiberglass grating is engineered with thicker bearing bars and deeper panel depths (typically 1.5" to 2.5" or more) to handle high loads, including vehicular or forklift traffic, making it stronger than standard FRP grating.
P:
What type of resin is best for heavy duty applications?
A :
For chemical and industrial environments, vinyl ester resin is preferred due to its excellent corrosion resistance. For general-purpose applications, isophthalic polyester is often sufficient. Phenolic resin is used where fire and smoke performance are critical.
P:
Is heavy duty FRP grating fire-retardant?
A :
Yes. Many heavy duty fiberglass grating options are available with fire-retardant formulations that meet ASTM E84 Class 1 standards for flame spread and smoke development.
P:
Is heavy duty FRP grating fire-retardant?
A :
Yes. Many heavy duty fiberglass grating options are available with fire-retardant formulations that meet ASTM E84 Class 1 standards for flame spread and smoke development.
P:
Can heavy duty fiberglass grating support forklift loads?
A :
Yes. Properly supported pultruded heavy-duty FRP grating can support H-20 traffic loads or even forklift traffic, depending on thickness, span, and support design.
P:
How does it compare to steel grating in strength and weight?
A :
Heavy duty FRP grating offers a comparable strength-to-load capacity with up to 75% less weight than steel, making it easier to install and resistant to corrosion without painting or galvanizing.
P:
Can it be used outdoors?
A :
Absolutely. It is UV-resistant, non-corrosive, and performs well in harsh outdoor environments including marine, coastal, and industrial settings.
P:
How is it installed?
A :
It can be cut on-site using standard carbide tools and installed with FRP or stainless steel clips. Proper support spacing and load calculations are important to ensure optimal performance.
