Our fiberglass composite deck planks are manufactured through a pultrusion process, which gives them more design flexibility along with a lighter weight, longer service life, and improved safety compared to steel or aluminum alternatives. Because FRP planks resist corrosion so effectively, they hold up well even where seawater exposure is severe.

Since the planks are lightweight, installation stays manageable even at remote sites where heavy machinery can’t reach. Despite being light, our FRP planks are still strong enough that heavy vehicle traffic passing over them isn’t a concern.
Years after a boardwalk is built with these planks, it still looks good, and unlike other boardwalk materials, it doesn’t need regular maintenance.

Key Features of Fiberglass Composite Deck:

Safety: Resistant to chemicals, corrosion, and alkali, with an anti-slip, anti-aging surface — together these give our FRP grating a strong safety record.
Stability: Thermal expansion and contraction run 24% and 50% lower than aluminum and steel respectively, giving the material greater dimensional stability.
Durability: Holds up better over time than stainless steel, aluminum, and galvanized gratings, especially where corrosion exposure is high.
Strength: Tensile strength runs 50% above hot rolled steel, along with better impact resistance.

Targeted Product FAQ

Q1: What makes fiberglass composite deck suitable for marine/coastal installations?

A1: Its corrosion resistance to seawater far exceeds steel or aluminum, and its light weight means it can be installed in remote coastal or waterfront sites where heavy machinery access is limited.

Q2: What sizes and colors of deck planks are available?

A2: Thickness, color, size, and punch-hole placement are all customizable — see the Customized Service options above or send us your project specification.

Q3: Is the deck surface slip-resistant when wet?

A3: Yes, our deck planks are manufactured with a textured, non-slip surface designed specifically for wet marine and waterfront environments.

Q4: Can fiberglass deck planks span the same distances as steel decking?

A4: Span capability depends on plank thickness and profile — share your support spacing and load requirements and we can help confirm the right plank specification.

Q5: How is fiberglass composite deck installed?

A5: Planks are typically fastened to a supporting frame using standard mechanical fixings — let us know your substructure and we can advise on the recommended installation method.
