With excellent corrosion resistance, strength, impact resistance, slip resistance and long service life, FRP grating is of the most useful, versatile, and economical solutions available for the construction of pedestrian walkways, dock decking, bridges, platforms and stairways, compared with more traditional materials such as galvanized steel, aluminum, stainless steel, or wood.
Interwoven high-strength glass rovings embedded in a thermosetting resin matrix, create one-piece structural panels which exhibit excellent bi-directional strength and one of the highest strength-to-weight ratios of any material.
We supply grating in 8′ x 4′ panels for optimum transportation, handling and installation and in three mesh sizes which satisfies all but the most specific decking applications. For such exceptional applications, we can usually supply other grating sizes, styles, resin composition and surface finish on request, subject to minimum order size.
Typical applications for this versatile decking product include:
Boardwalks
Dock decking for jetties & pontoons
Ramps for the disabled
Pedestrian bridges
Rooftop access walkways
Viewing platforms
Industrial work platforms
Stairs and landings
Beach access
Benefits of Fiberglass Grating
Lightweight – only 1/4 the weight of steel and 1/3 the weight of aluminum
High strength – tension, compression and bending strength similar to steel
High impact resistance - springs back to original shape when deflected
Excellent slip-resistance with bonded grit surface
Long life span – typically in excess of 25 years
High fire resistance, low flame spread index, and low toxic fumes with selected resins & fillers
Highly resistant to corrosive chemicals
Unaffected in marine environments and prolonged exposure to wet conditions
Uniform color and appearance
Easy on-site fabrication and/or trimming
Green roofs have become increasingly popular in recent years, and in some locations have become mandatory, with rooftop plantings reducing energy costs, improving air quality, increasing biodiversity and reducing storm water runoff. One of the easiest methods of creating an instant green roof is to use plastic planter trays filled with growing medium and plants.
We supply unfilled modular plastic trays which you can then fill on site with around 4 inches of growing media and small, low-growing plant species such as succulents that require minimal maintenance and relatively low water needs. Although trays may often be placed directly on the rood surface, in many cases, there's a need to elevate the trays to avoid service pipes, electrical conduits and surface irregularities, or raise the plantings to match the height of paved areas, or to correct for the slope on the roof space.
Fiberglass grating panels supported by adjustable height pedestals undoubtedly offer the most effective and versatile means of supporting raised planter trays. The fiberglass panels not only provide a solid base for the planter trays but can provide support for pavers set among the plantings – porcelain, stone or concrete. Expanded polystyrene (EPS) foam is combustible and labor-intensive to install while concrete pavers are extremely heavy and may exceed roof loadings with filled planter trays.
Some of the other benefits of using fiberglass grating panels to elevate and support an extensive green roof tray system include:
less pedestals needed c.f. concrete pavers
large panel size (typically 4′ x 8′) ensures much faster installation
superior wind uplift protection – interconnected panels create a continuous surface
allows space for irrigation pipes under the plantings
water drains freely via the open grid structure
minimizes weight loading – just 2.5 – 4 lb/sq.ft. (depending on panel thickness)
Archatrak fiberglass grating panels offer the most cost-effective and technically advanced support system for laying synthetic turf on rooftops where you want a perfectly level surface with good drainage and secure fastening so it won't blow away.
Our 4' x 8' ‘MiniMesh' grating panels have apertures of just ¼", ensuring a ensuring a solid base but allowing rapid drainage of water and eliminating pooling, both critical factors in synthetic turf installations. The slight ‘give' characteristic of fiberglass gratings rovides a more comfortable and natural feeling underfoot compared with installations over a very hard surface like concrete.
The large 4' x 8' panels can be securely locked together with stainless steel clips and secured to the parapet surrounding the deck area, offering a totally connected surface that is highly resistant to wind uplift. The turf itself can be secured to the grate by adhesive and also by mechanically fixing it to battens under the grate, or more simply by using 1/4″ diam. aluminum rivets.
In addition, fiberglass panels do not add significantly to the weight loading on a roof deck. At only 3.5-4.0 lb. per sq.ft., they are much lighter than concrete or porcelain pavers. Even when filled with sand to stabilize the artificial turf pedestal system, the total weight of the grating plus turf will be less than 7 lb. per sq.ft.
Archatrak is a national supplier of exterior porcelain pavers, structural and interlocking wood deck tiles, FRP, and deck support systems. For the past two decades we have played a leading role in the introduction and market development of both interlocking deck tiles and structural porcelain pavers for creating exceptional outdoor environments.
Whether it's elevated rooftop decks on pedestals, on-grade paving over sand or gravel, resurfacing of existing concrete, or mortar set paving for vehicular applications, we supply the means to create outdoor spaces with unique character and lasting appeal, both residential and commercial.
