Archatrak SpanTrak fiberglass (FRP) grating panels provide a strong, stable, and corrosion-resistant solution for boardwalks, marina decking, pedestrian bridges, and other pedestrian-focused applications where long-term performance, safety, and minimal maintenance are essential.
With a superior strength-to-weight ratio, inherent corrosion resistance, and long service life, SpanTrak FRP grating panels are well suited for waterfront, coastal, and remote trail applications exposed to moisture, humidity, and heavy foot traffic.
Optional gritted surface finishes combined with open-grid panel designs provide consistent traction and drainage in wet, exposed, and high-traffic environments.
FRP panels offer a high strength-to-weight ratio, making them easier to handle and install while supporting pedestrian loads without sacrificing structural performance.
Unlike steel or wood, FRP grating resists corrosion from water, salt, and many chemicals, making it well suited for coastal, waterfront, and industrial environments.

Molded FRP grating is an excellent choice for a variety of industrial applications.
Fully sealed and self-contained, these fixtures provide continuous, full-power lighting from dusk until dawn, 365 days a year, without trenching, conduit, or grid power.
Exceptionally durable, slip resistant, and fire resistant, FRP boardwalk decking outperforms traditional softwood, hardwood, steel, composite wood, and precast concrete across virtually every measure that matters for boardwalk construction.
Supplied in 4′ x 8′ panels with a bonded grit surface, Archatrak SpanTrak FRP grating provides a stable, slip resistant deck surface capable of supporting heavy foot and bicycle traffic in all weather conditions. The large-format panels help eliminate warped or decayed boards that create trip hazards, while the molded grit surface resists moss and…
Archatrak SpanTrak FRP grating has earned an enviable reputation in marina and dock construction for its strength-to-weight ratio, long-term durability, and exceptional slip resistance. Unlike steel, FRP will not corrode. Unlike wood, it will not decay, crack, warp, or splinter in wet environments.

FRP (fiberglass reinforced polymer) grating is a composite material made from fiberglass and resin, designed to provide a strong, corrosion-resistant walking surface in demanding environments. It is commonly used for boardwalks and walkways because it does not rot, rust, or corrode and performs well in wet, coastal, industrial, and high-exposure settings where traditional materials may deteriorate over time.
Yes. FRP grating is engineered to support pedestrian loads when properly specified and installed. Its high strength-to-weight ratio allows panels to provide structural performance while remaining relatively lightweight, which can simplify handling and installation in remote or difficult-to-access locations.
FRP boardwalk and walkway systems are commonly used in waterfront and marina settings, wetlands and natural areas, industrial facilities, pedestrian bridges, and access walkways. They are often selected for sites where durability, slip resistance, and resistance to environmental exposure are critical.
