FRP Grating Panels - An Effective Substrate for
Pedestal Elevated Pavers
and Synthetic Turf on Rooftop Decks
Many landscaped rooftop decks and terraces entail large formal pavers or wood tiles elevated on pedestals over top the waterproof membrane. Pedestals enable the pavers to be leveled over the roof structure, which is sloped for water drainage. FRP grating is an ideal landscape solution for elevating pavers, pebbles or synthetic turf, plus protecting against large format pavers getting cracked.
Fiberglass Reinforced Grating (FRP) in 4’x8’ and 4’x12’ sheets is an extremely durable and high load-bearing product ideal for providing support to synthetic turf, green roof trays, planters or pavers elevated on pedestals.
Grates with 1/2” x 1/2” square mesh openings are used when supporting turf and landscape pebbles, while grates with 1 1/2” x 1 1/2” mesh openings are commonly used to support pavers, green roof trays and planter boxes.
1” thick grates are commonly used for any application, while 1 1/2” and 2” thick grates are available. Optional fasteners are available to secure adjoining grates, and grates to pedestals and joists as necessary.
FRP Flammability Information:
The entire FRP Grating industry goes by ASTM E-84 (25 or Less). A rating of 25 or less on the ASTM E84 (Standard Test Method for Surface Burning Characteristics of Building Materials) corresponds to Class "A" (or Class I) flame spread classification.
ASTM E84 Flame Spread Classes:
Class A (Class I): 0–25 (least flammable)
Class B (Class II): 26–75
Class C (Class III): 76–200
Since 25 or less falls within the Class A range, it means the material has excellent fire resistance with minimal flame spread.
