NIGP 66537: Gratings: Fiberglass, Plastic, Poly., etc.

NIGP 66537 Gratings: Fiberglass, Plastic, Poly., Etc., an Item code, encompasses the supply of fiberglass grating panels for infrastructure and industrial applications where corrosion resistance, durability, and anti-slip performance are required. State and local governments currently procure fiberglass grating for pedestrian bridge construction, walkway replacement projects, and industrial facility upgrades — including trench systems, drainage structures, and heavy-duty traffic-bearing surfaces in port and municipal environments. The work is straightforward material supply with specifications for panel dimensions, resin composition, anti-skid surface treatment, fastening hardware, and delivery logistics; installation may be performed by the customer or by contractor forces depending on the scope. Issuing bodies include state departments of transportation, city solid-waste and environmental divisions, and municipal public-works procurement offices. Michigan Department of Transportation and the City of Tampa represent recent repeat activity under this code.

Recent activity concentrates in Michigan and Florida. The Michigan Department of Transportation posted multiple RFPs in May 2026 for DURAGRID Series T-1700 T-Bar pultruded grating panels (70 total panels in five size configurations) for the Merrick Avenue Walkway pedestrian bridge in Detroit, with proposals due May 19, 2026 and an award recommendation issued May 26, 2026 to GFG Supply Inc. of The Villages, Florida for a total contract value of $88,060. The City of Tampa Solid Waste & Environmental Program Management division issued an RFQ in September 2026 (26P00536) for fiberglass grating to replace steel grating at McKay Bay, requiring two custom units measuring 1.25 inches tall by 2 feet 2 inches by 117 feet, with specifications for drainage hole size, anti-split textured surface, and FOB Destination delivery, with quotes due September 1, 2026. Both opportunities emphasize technical specification compliance, insurance and employment verification requirements, and firm fixed pricing that includes all freight and handling charges.
