Updated

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Most US manufacturers and large distributors do not publish prices, so public prices come from a few online stores, retailers and distributors.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.

Notes

  1. 1Public market benchmark, not a Strongrate price.
  2. 2Reported ranges from vendor price guides (2025 or undated, read Oct 15, 2026), not seller quotes and not Strongrate prices.
  3. 3Public retail benchmark for a small panel, not a Strongrate price.
  4. 4Published by US sellers; not Strongrate’s minimum order.
  5. 5Rate 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 walks through the arithmetic.

Grating made in China does not qualify for federally funded public works under Build America, 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.
