# Fiberglass Grating Price: How Much Does It Cost per Square Foot?

_Updated Oct 17, 2026_

US sellers listed molded fiberglass grating panels 1" (25 mm) deep and deeper at about $9 to $24 per sq ft on Oct 15, 2026, depending on depth, resin, surface, panel size and quantity. Those are market benchmarks from other sellers. Strongrate prices are quoted per project: [request a quote](https://www.strongrate.us/request-quote/) and we reply within 1 business day (US Central time).

## What do US sellers charge for fiberglass grating?

Most US manufacturers and large distributors do not publish prices, so public prices come from a few online stores, retailers and distributors. The tables show them as listed on Oct 15, 2026, on each seller’s own terms, usually USD F.O.B. the seller with freight extra. None of them is a Strongrate price.

## Why does fiberglass grating cost so much more in some listings?

**What moves the price of fiberglass grating, with market evidence (USD)**

| Price driver | What changes | Market evidence (benchmarks, not Strongrate prices) |
| --- | --- | --- |
| Depth | Deeper grating uses more material per sq ft | US online FRP grating store: about $9–$10/sq ft at 1" (25 mm) deep, $13–$14 at 1-1/2" (38 mm), $15 at 2" (51 mm) [note 1] |
| Grating type | Pultruded grating is usually priced above general molded grating | Price guides: molded $12–$18/sq ft, pultruded $20–$28/sq ft [note 2] |
| Resin | Specialty resins, such as vinyl ester or phenolic, cost more than general-purpose resins | Price guides: specialty-resin molded $22–$30/sq ft; phenolic $25–$32/sq ft [note 2] |
| Surface | A grit top adds material and a process step | Price guides: grit adds $1–$3/sq ft [note 2] |
| Color | Some colors are priced higher | Puerto Rico metals distributor: $499.95 to $750.95 for the same 4 ft × 8 ft (1220 × 2440 mm) panel, by color [note 1] |
| Panel size | Small panels cost more per sq ft than full-size panels | A 2 ft × 4 ft (610 × 1220 mm) retail panel, 1-1/2" (38 mm) deep: about $17.37/sq ft [note 3] |
| Quantity | Larger orders usually cost less per sq ft | US stocking distributors and online stores sell by the single panel; published prices drop at volume quantities [note 4] |
| Freight terms | Listed prices are usually F.O.B. the seller; delivery is added | US sellers commonly quote USD F.O.B. their factory, freight separate |
| Import duty | Grating made in China pays US duty on entry | About 42.8% of dutiable value as of Oct 2026 (HTS 3925.90) [note 5] |
| Raw material costs | Resin and oil prices feed through as surcharges | A US maker was adding a 7% surcharge to all invoices as of Oct 2026 |

_Listing prices were accessed Oct 15, 2026._

Notes:

1. Public market benchmark, not a Strongrate price.
2. Reported ranges from vendor price guides (2025 or undated, read Oct 15, 2026), not seller quotes and not Strongrate prices.
3. Public retail benchmark for a small panel, not a Strongrate price.
4. Published by US sellers; not Strongrate’s minimum order.
5. Rate as of Oct 2026. Excludes the Merchandise Processing Fee, Harbor Maintenance Fee and any Section 232 duty on steel hardware; rates can change. Confirm with your licensed customs broker.

## Factory-direct or US stock: which price applies to your order?

US stock costs more per sq ft but ships in days and sells by the panel. Factory-direct from Nantong suits full containers and project quantities; you take on ocean freight, US import duty and lead time. Orders under about 500 sq ft, or needed in under 3 weeks, are referred to a US stocking importer.

On FOB or CIF terms, add US duty to the factory price: about 42.8% for China-origin grating under HTS 3925.90 as of Oct 2026 (confirm with your licensed customs broker), plus ocean freight, customs fees and delivery. The [landed cost, duty and freight guide](https://www.strongrate.us/buy-direct/landed-cost-duty-and-freight/) walks through the arithmetic.

Grating made in China does not qualify for federally funded public works under [Build America, Buy America (BABA)](https://www.strongrate.us/buy-direct/buy-america-baba/). Private and industrial projects are not affected.

## Frequently asked questions

### How much does a 4 ft × 8 ft molded fiberglass grating panel cost?

On Oct 15, 2026, US sellers listed 4 ft × 8 ft (1220 × 2440 mm) molded panels 1-1/2" (38 mm) deep at $491.60 (a US car-wash equipment supplier) and at $499.95 to $750.95 depending on color (a Puerto Rico metals distributor); a US-brand vinyl ester panel 1" (25 mm) deep was $778.99 on a national MRO website. These are benchmarks, not Strongrate prices.

### Why do most fiberglass grating suppliers not publish prices?

Most US manufacturers and large distributors quote each order, because price depends on type, depth, resin, surface, panel size, quantity and freight. Public prices come mainly from a few online stores, retailers and marketplaces.

### Do published fiberglass grating prices include freight and import duty?

Usually not. US sellers quote F.O.B. their factory or warehouse with freight extra. A Strongrate quote states its Incoterm: FOB and CIF prices exclude US import duty (about 42.8% for China-origin grating as of Oct 2026; confirm with your licensed customs broker), and a DDP price includes it.
