- Pultruded Grating
Pultruded FRP Grating is made by pulling continuous fiberglass rovings through a resin bath and heated die, forming high-strength load-bearing bars. It offers superior strength-to-weight ratio, excellent corrosion resistance, and long service life for demanding industrial environments.
Machs is a trusted expert in FRP grating manufacturing with over 20 years of industry experience. Our pultruded FRP grating is engineered for industrial walkways, platforms, and environments exposed to corrosion. Available in multiple sizes, colors, and surface options, our products combine high strength, durability, and chemical resistance to meet the demands of harsh operating conditions.

FRP Grating
Key Features: Pultruded vs. Molded Grating
Pultruded FRP grating offers higher strength and longer spans than molded grating. Its continuous fiberglass rovings and I/T-bar design give it superior load capacity and stiffness in the bearing bar direction, making it ideal for heavy-duty walkways and platforms. Compared with molded grating, it is lighter, has better directional strength, and supports more custom sizes and open area options.
Applications
Pultruded FRP Gratings are widely used in walkways, platforms, trench covers, mezzanines, and stair treads across chemical processing, marine, wastewater treatment, food & beverage, and oil & gas industries.

Pultruded Grating - FAQS
Q1: What is the difference between pultruded and molded FRP grating?
Pultruded grating has higher glass content and directional strength, making it ideal for long spans and heavy loads, while molded grating is isotropic and better for areas needing frequent cutouts.
Q2: Can I customize the size and color of my grating?
Yes. We offer a wide range of bar shapes, depths, panel sizes, and colors (grey, yellow, green) to meet your project requirements.
Q3: Is pultruded grating slip-resistant?
Yes. You can choose a grit surface for maximum slip resistance or a smooth surface for easy cleaning.
Q4: How strong is pultruded grating compared to steel?
It provides a high strength-to-weight ratio, is about one-third the weight of steel, and resists corrosion, making it easier to install and maintain.
Q5: What industries commonly use pultruded grating?
It’s widely used in chemical plants, wastewater treatment facilities, offshore platforms, food processing areas, and other corrosive environments.
