Fiberglass grating suppliers for US buyers fall into three groups: established manufacturers, US stocking distributors and importers, and overseas factories. Buy factory-direct from Nantong for full containers and project quantities. Use a US stocking importer for orders under about 500 sq ft or needed in under 3 weeks: US stocking distributors ship in-stock grating within a few days, some the same day.
What kinds of fiberglass grating suppliers sell in the US?
Most US buyers meet the same products through several layers: manufacturers make the grating, distributors and importers stock and cut it, and catalogs and retailers sell standard panels online. Third-party customs records show US distributors and manufacturers regularly importing FRP grating from Chinese factories, and most US sellers’ websites do not state the country of origin, so ask every supplier where its grating is made. Most US manufacturers and large distributors do not publish prices online.
| Fiberglass grating suppliers | Who they are | How they price | Shipping speed | Worth knowing |
|---|---|---|---|---|
| Established grating manufacturers | US makers, including the members of ACMA’s Fiberglass Grating Manufacturers Council | USD F.O.B. their factory, freight quoted separately | Stated in each quote | Published grating warranties run 1–3 years1 |
| US stocking distributors and importers | Regional and national sellers holding US stock; much of it is imported | Sell by the single panel; published prices drop at volume quantities2 | In-stock grating within a few days, some the same day; items ordered in or fabricated take longer3 | Payment terms such as net 30 days usually only after credit approval4 |
| Overseas factories | Jiangsu Province, and Nantong in particular, is a center of export FRP grating manufacturing | Generally FOB a Chinese port | Production plus ocean transit | About 42.8% total US duty on China-origin grating as of Oct 20265 |
| Strongrate, factory-direct from Nantong | Manufacturer in Nantong, Jiangsu, China; ships from China | Quoted per project in USD, with the Incoterm and quote date | Production time stated in your quote, plus 14–20 days ocean transit Shanghai to Los Angeles6 | Full containers and project quantities; small or urgent orders are referred to a US stocking importer |

When should you buy from US stock instead of factory-direct?
Our rule is simple: factory-direct for full containers and project quantities, US stock for small or urgent orders. Ocean transit alone takes about 14–20 days from Shanghai to Los Angeles and 30–40 days to New York/New Jersey, before production time and US delivery, so a need-by date under 3 weeks cannot be met from Nantong.
| Your order | Best source | Why |
|---|---|---|
| Under about 500 sq ft | A US stocking importer (we refer you) | Even a few panels from China need a customs entry and pay duty |
| Needed in under 3 weeks | A US stocking importer (we refer you) | Ocean transit from Shanghai to Los Angeles alone takes 14–20 days1 |
| Full containers or project quantities, with time for production and ocean freight | Factory-direct from Nantong | Quoted in USD with the Incoterm and quote date; made in Nantong and shipped by ocean freight |
| A distributor or importer restocking a warehouse | Factory-direct from Nantong | Container quantities; choose “Distribution and resale” on the contact form or send a quote request |
| Federally funded infrastructure covered by BABA | A manufacturer that makes the grating in the US | Grating made in China does not qualify under BABA |
| A specification that requires US manufacture | A manufacturer that makes the grating in the US | Some US guide specifications state that gratings shall be manufactured in the USA |

How does a referral to a US stocking importer work?
How a small or urgent fiberglass grating order is referred
Step 1: Send a quote request
Use the FRP grating quote form with the product, quantity, destination ZIP code and need-by date. The form shows the likely route before you send it.
Step 2: We check the route
Orders under about 500 sq ft, or needed in under 3 weeks, are marked for referral. Federally funded public works are not quoted.
Step 3: We forward your request
We send it to one US importer that stocks fiberglass grating and tell you which one, so you know who will contact you.
Step 4: The importer quotes you
It quotes from its own US stock and sells under its own price, warranty, payment and return terms. Strongrate is not the seller in that sale.
What is our pricing-parity policy?
Indicative prices we publish on this site are not set below the prices of the US stocking importers we refer customers to. Factory-direct supply is for container and project quantities; it is not meant to undercut the importers that hold US stock for small and urgent orders. See fiberglass grating price per square foot for dated market benchmarks.
How do you check a fiberglass grating supplier?
Ask every supplier the same questions, in writing, before you order.
| What to ask | Why it matters | Strongrate |
|---|---|---|
| Where is the grating made? | Federal funding rules and some specifications require US manufacture | Nantong, Jiangsu, China; ships from China |
| ASTM E84 results on the finished grating | US guide specifications require a flame spread index of 25 or less1 | Flame spread index 5–20 for the six DNV-listed models2 |
| Load and deflection tables, with the safety factor stated | Makers use safety factors from 2:1 to 5:1, so their tables are not directly comparable | Strongrate’s 2023 catalog load tables; confirmed in your quote and submittal drawings3 |
| Third-party certificates | US guide specifications ask for a certified quality-management system and proof of other certification programs | DNV Type Approval TAF0000191 Rev. 1 is the only documented certificate4 |
| Samples or a pilot order | Guide specifications ask for samples of each product type for approval | Order a sample |
| A written warranty | Published grating warranties run 1–3 years5 | Stated in your written quote and order confirmation |
| Lead time and minimum order in writing | Supply from stock and supply produced for the order differ widely in lead time | Stated in your quote |
| The price basis: Incoterm, port and date | A price means little without its Incoterm, port and date | USD, with the Incoterm and quote date, in every quote |
Notes
- 1A specification threshold, not a test result.
- 2Applies only to the six models listed on DNV certificate TAF0000191 Rev. 1.
- 3Catalog tables; confirm the values for your span in the submittal before final design.
- 4A search result, not a statement from the factory.
- 5Other suppliers’ warranties, shown as benchmarks; Strongrate’s warranty is stated in your quote.
Is there a fiberglass grating supplier near me?
Strongrate has no US warehouse or office: grating is made in Nantong, China, and ships from China. For stock panels near you, send a quote request and we refer small or urgent orders to a US stocking importer. For container quantities, where delivery ends (a Chinese port, a US port or your site) depends on the Incoterm in your quote.
Frequently asked questions
Why are the US importers we refer to not named?
We name an importer only with its written consent. When we refer your request, we tell you which importer will contact you.
Can distributors buy Strongrate grating by the container?
Yes. Distributors and importers can request factory-direct quotes for full containers; choose “Distribution and resale” on the contact form or send a quote request. Your quote states the container loading, minimum order and Incoterm.
How fast do US stocking distributors ship fiberglass grating?
US stocking distributors ship in-stock grating within a few days of the order, some the same day; items they must order in or fabricate take longer. A factory-direct order adds production time and ocean transit.
