HDG Grating Panels

HDG Grating Panels are molded grating products made of fiberglass reinforced plastic (FRP). HDG molded gratings are available in a variety of resins, standard and custom colors, depths, panel sizes and mesh configurations. Surface options include a meniscus or integrally applied grit top, both of which offer superior, slip resistant footing. Grating can also be mechanically fastened to the tops of Buzon pedestals.

HDG Silca Grates

HDG Silca Grating panels are smaller 2SF panels that are designed to be set on top of or in-between wood joists set 16″ o.c. These are typically used to renovate or build new residential decks, but may be used on commercial projects.

Barefoot Friendly Grit

Integrally Applied Grit



HDG grating panels are used in place of traditional materials and offer many advantages over steel grating or decking.

We have gone to contract for the finish carpentry portion of the project and are hopefully working out the final details of the 5th level exterior deck scope today. I appreciate the clarity you have provided thus far, I wish everyone could be so detailed!

Available Surfaces for HDG Grating Panels

Meniscus Top

The concave surface of meniscus top grating provides superior slip resistant footing in most environments including wet or oily conditions.

Integrally Applied Grit Top

This grit top surface has a quartz grit which is integrally applied, cured and sealed onto the surface providing excellent slip resistant footing. Also available in a barefoot friendly aqua grit (sugar-grit).

FRP Conductive Surface

Our factory can provide secondarily applied conductive surfaces which drains off the build-up of unwanted, dangerous static electricity when properly grounded. This specialized surface produces an electrical resistance of less than 26 kilo-ohms per foot, while the grating retains all of the other desirable corrosion resistant, fire retardant, impact resistant and lightweight characteristics of conventional fiberglass reinforced plastic (FRP) grating.

Grating Panels Featured Project

601 City Center T12 Oakland CA

This complex commercial project in the Bay Area involves a couple of plazas. The client wanted multiple size pavers set to create a sloped walking surface over an uneven substrate. Adding to the complexity the pavers would be set at an angle to the slope as well! HDG met on conference call with the project owner’s PM, the GC, engineer, architect, and landscape architect. HDG went through dozens of emails clarifying plans and details to help client figure out their design using a combination of Buzon screwjack height-adjustable pedestals (with both top and bottom slope correctors), HDG Grating Panels and Structural Porcelain Pavers. This allowed the client to tie the plaza finished walking surface to the finished floor of the building and to the public sidewalk grades. See full project details and photos in this featured Sloped Surface Design Using Grating Panels project blog post.

Transform a Wood Deck Into a Stone Deck

HDG Silca Grates are a unique product used to create a sub-base over wood floor joists. Structures created using HDG Silca Grates can accommodate natural stone, porcelain pavers, and other decking materials.

HDG Silca Grates Featured Project

Luxury Residential Mountain Retreat

This elevated wood joist deck would not ordinarily accommodate stone pavers or porcelain pavers. This large wrap-around deck constructed with wood joists was topped with HDG Silca Grates and then covered with stone-finish porcelain pavers. This method of elevated deck construction offers tremendous advantages especially in a mountain setting since the porcelain pavers are impervious to freeze-thaw cycle and are easy to maintain.
