Our pultruded fiberglass grating delivers good strength, durability, and corrosion resistance for industrial flooring, platforms, and walkways. Manufactured through an advanced pultrusion process, this engineered composite combines continuous glass fibers with quality resins to create strong load-bearing capabilities while remaining lightweight and low-maintenance.
What Makes Pultruded Grating Different?
Pultruded fiberglass grating is manufactured using a specialized continuous process that creates unidirectional strength through aligned glass fibers. This results in a product that offers:
| Feature | Pultruded Fiberglass Grating | Traditional Alternatives |
|---|---|---|
| Weight | much lighter than steel for equivalent load capacity | Steel requires heavy equipment to install |
| Corrosion Resistance | resistant to most chemicals | Steel corrodes, requires painting |
| Maintenance | Low-maintenance | Metal requires ongoing rust prevention |
| Strength | High unidirectional strength | Steel can lose strength as corrosion occurs |
| Safety | Non-conductive, non-sparking | Metal conducts electricity, can spark |
| Lifespan | long service life | shorter in corrosive areas |
| Installation | Easy cutting and drilling on-site | Requires welding, heavy equipment |

The Manufacturing Process
Our pultruded fiberglass grating is produced through a precision-controlled process:
- Fiber Preparation: Continuous glass rovings and mats are carefully arranged to provide optimal strength characteristics.
- Resin Infusion: Fibers are thoroughly impregnated with quality resin systems selected for specific environmental requirements.
- Profile Formation: The resin-saturated fibers are pulled through heated dies to create precise I-bar or T-bar profiles.
- Crossrod Integration: Perpendicular crossrods are installed at precise intervals and bonded with epoxy adhesives.
- Quality Control: Every panel undergoes rigorous testing to ensure consistent performance and dimensional stability.
This manufacturing process creates a strong product with good resistance to chemicals, UV exposure, and physical stress.

Frequently Asked Questions
How long will pultruded fiberglass grating last in my facility?
In most industrial applications, our pultruded grating has a long service life with minimal maintenance. Even in chemical processing environments where steel gratings typically require replacement every 2-3 years, our fiberglass grating shows minimal degradation over long service life.
Can it be cut to fit around pipes and equipment?
Yes, one of the major advantages of pultruded grating is easy on-site modification. Standard power tools with abrasive or diamond-tipped blades can be used to make precise cuts. We also offer factory fabrication services for complex layouts.
How does the load capacity compare to steel grating?
Our pultruded grating provides comparable load-bearing capacity to steel when properly specified. For typical walkway applications (100 psf/4.8 kN/m²), our 1″ deep grating with 1.5″ × 1.5″ mesh can span up to 42″ with minimal deflection. For heavier loads, our 1.5″ deep grating offers enhanced capacity.
Is it suitable for areas with heavy foot traffic?
Absolutely. The surface maintains its slip resistance and structural integrity even with continuous foot traffic. Many airports, processing plants, and public facilities have had our grating in high-traffic areas for long service life with minimal wear.
How does it differ from molded fiberglass grating?
While both products offer corrosion resistance, pultruded grating offers:
- Higher load capacity for the same depth
- Ability to span greater distances between supports
- Enhanced unidirectional strength for walkways and platforms
- More precise dimensional consistency
- strong performance in beam-loading applications
How environmentally friendly is this product?
Our pultruded grating contributes to sustainability through:
- Long service life
- Potentially lower lifetime carbon footprint than repeated replacement of metal gratings
- No toxic treatments, coatings or leachates
- Lightweight design reducing transportation emissions
- no VOC emissions during service
