Here Molded FRP Grating with 1.5″ x 1.5″ holes on center was used. National Grating also supplies 2″ and 1″ as well as Mini Mesh Molded Grating that has a ¾” grid pattern with ½” open squares.

Project

110 FT of National Grating FRP Molded Grating Marina decking installed in a Pacific Ocean Marina.

A marina on the Pacific Coast of British Columbia required 110ft of dock to be replaced.  The contractor decided to contact National Grating to explore FRP Solutions.  They decided on Grey Molded FRP Grating with 1.5” gaps to replace the decking section of this dock.

Grey Molded FRP Grating with 1.5” x 1.5” gaps with gritted top coating for added slip resistance in wet environment.


Why was Molded FRP Grating Chosen?

Molded FRP Grating from National Grating was perfect for this application because of its anti-corrosion properties, durability, strength and lightweight nature, and its ability to let sun and water pass through the grating.

Corrosion Resistance

FRP grating is highly resistant to corrosion, making it durable in harsh marine environments.

Anti-Slip Properties

The concave and anti-slip grit surface provides excellent anti-slip properties, ensuring safety for pedestrians, even in wet conditions.

Durability and Longevity

FRP grating is highly durable, resistant to saltwater, UV rays, and corrosion, making it ideal for marine environments.

Strength and Durability

FRP grating is engineered to withstand heavy loads making it ideal for docks and marinas. FRP Grating has a high strength to weight ratio allowing for a strong structure that is also lightweight.  While comparable in strength, FRP grating is significantly lighter than steel, making it easier to install without heavy lifting equipment.

Open Area

The open area of Molded FRP Grating is an important factor in environmental sustainability, allowing sun to pass through to plants, seagrass, and other shallow marine habitats beneath the decking surface. 

During storms the open area also allows wind and water to pass through lessening the stress on the dock structure and mounting hardware.

Molded FRP Grating

Common sheet sizes for Molded FRP grating include: 4’x8′, 4’x12′, and 3’x10′. Common thicknesses include: 1″, 1.5″ and 2″.

Pultruded FRP Grating

Fiberglass Grating pultrusion’s come in three categories: I-Shape bars, T-Shape bars, and High-Load bars for heavy duty applications. The bearing bars are interconnected with cross-rods every 6 inches. 

Mini Mesh FRP Grating

Mini-Mesh fiberglass grating has a ¾” grid pattern with ½” open squares. This results in 44% open area which allows light and water to pass through and provides a very comfortable decking surface to walk on in bare feet.

Stair Treads and Covers

Pultruded FRP Stair Treads were used here for a safe and anti corrosive solution to enter and exit the lake at this private dock.

Fiberglass stair treads are available as molded FRP treads with yellow nosings and a gritted surface, for the ultimate in safety.

Fiberglass stairs are the best solution for outdoor anti-slip stairs. They outlast traditional building materials and are easy to install. Stair treads made of FRP grating are lightweight, easy to fabricate, and highly durable.
