Fiberglass grating is a composite material made of fiberglass reinforcements embedded in a resin matrix. It offers real advantages over conventional metal gratings — corrosion resistance, fire retardance, impact resistance, low maintenance, low conductivity, light weight, and bidirectional load bearing. It’s widely used across industrial applications like flooring, platforms, storage areas, walkways, trenches, and assembly lines.
Not all fiberglass grating products are equal, though. Depending on design and manufacturing, different types deliver different levels of strength and durability. For applications needing heavy loads — like fork truck traffic — over long spans in corrosive environments, standard fiberglass grating may fall short. That’s where heavy duty fiberglass grating comes in.
What Is Heavy Duty Fiberglass Grating?
Heavy duty fiberglass grating is a specialized type built specifically to carry heavy rolling loads and high static loads over long spans — able to withstand loads that traditional molded and pultruded fiberglass grating can’t support. It’s available in both molded and pultruded forms.
Molded heavy duty fiberglass grating is made by placing continuous strands of fiberglass roving in a mold and injecting resin to form a solid panel, then curing and removing it from the mold. This one-piece construction delivers excellent corrosion resistance and bi-directional strength.
Pultruded heavy duty fiberglass grating is made by pulling continuous strands of fiberglass roving through a resin bath and then a heated die to form the desired shape. The pultruded bars are then assembled into panels via mechanical or adhesive bonding — a high fiber content gives superior stiffness and strength.
Why Choose Heavy Duty Fiberglass Grating?
Heavy duty fiberglass grating offers real advantages over conventional metal gratings or standard fiberglass gratings for industrial applications:
Durability: withstands harsh conditions — chemicals, moisture, UV rays, temperature swings — without rusting, rotting, warping, or cracking under stress. A long service life with minimal maintenance.
Performance: supports heavy rolling loads (like fork trucks) and high static loads (like storage tanks) over long spans without sagging or bending. A high strength-to-weight ratio and low deflection rate, and it reduces noise and vibration compared to metal gratings.
Safety: fire retardant, meeting the ASTM E-84 flame spread rating of 25 or less. Also slip resistant with a non-skid surface that helps prevent accidents, and electrically non-conductive — no sparking when struck by metal objects.
Cost-effectiveness: more economical over time than metal gratings or standard fiberglass gratings — lower initial cost than metal, and lower life-cycle cost than standard fiberglass, thanks to its light weight and easy-to-cut properties reducing installation and labor costs.
How to Select the Right Type of Heavy Duty Fiberglass Grating
A few key factors to weigh:
Load requirements: your application’s load requirements determine the thickness, depth, spacing, and shape of the bars or strands making up the panel. Consult the manufacturer for load tables and specifications for each product type.
Span length: determines the maximum distance between supports or frames holding the panel. Choose a type that spans your required distance without exceeding the allowable deflection limit.
Corrosion resistance: determines the resin system used to bond the fibers — polyester, vinyl ester, phenolic, or epoxy, depending on the chemicals and temperatures your application faces.
Surface options: determine the finish or coating applied — smooth, gritted, concave, or covered — based on your aesthetic and functional needs.
Conclusion
Heavy duty fiberglass grating is a durable, cost-effective solution for industrial applications needing heavy loads at long spans in corrosive environments — offering real advantages over conventional metal gratings or standard fiberglass gratings, including corrosion resistance, fire retardance, impact resistance, low maintenance, low conductivity, light weight, and bidirectional load bearing. Available in both molded and pultruded forms, it can be customized to fit various load requirements, span lengths, corrosion resistance levels, and surface options.
