Tell us the product, how you will use it and where to ship it; the reply confirms sample size, cost and shipping. Samples ship from Nantong, China, and pay US duty, because de minimis entry is suspended for Chinese goods (as of Oct 2026). _Use the sample request form on the web page: https://www.strongrate.us/samples/_ A question before you request a sample? [Contact Strongrate](https://www.strongrate.us/contact/). How the details you send are stored and shared is set out in the [privacy policy](https://www.strongrate.us/privacy/). Since May 2, 2025, de minimis duty-free entry has been suspended for goods from China, and it was still suspended as of Oct 2026, so a sample from Nantong needs a customs entry and pays duty like any other import. Your licensed customs broker or the courier can confirm the charges. ## Which fiberglass grating products can I sample? Pick the product in the form; if you are comparing options, list them in the notes.

Often: US guide specifications for section 06 74 13 require samples of each product type with the submittal. If your sample is for a submittal, name the specification section and the products in the notes. See [fiberglass grating specifications](https://www.strongrate.us/resources/fiberglass-grating-specifications/). ## When is a pilot order better than a sample? When you need to check full panels, packing and installation, not just the material. A pilot order is a normal order: under about 500 sq ft it goes to a US stocking importer under our [routing rule](https://www.strongrate.us/fiberglass-grating-suppliers/), and larger ones get a [factory quote](https://www.strongrate.us/request-quote/). ## Frequently asked questions ### How long does a grating sample take to reach the US? A sample ships by courier from Nantong and needs a US customs entry before it is delivered, so give the date you need it by in the notes field. The reply confirms dispatch and the courier. ### Will my production order match the sample I approved? Keep your approved sample and name it in your purchase order, so the order confirmation refers to it as the reference for color and surface. ### Can I sample more than one resin, color or surface? List each option you are comparing in the notes field; the reply confirms which of them can be sampled. ## Related pages - [Request an FRP grating quote](https://www.strongrate.us/request-quote/): Request an FRP grating quote: send drawings and quantities; container and project orders get a factory quote from Nantong, small or urgent orders are referred to a US stocking importer, and federally funded work is screened for Buy America. - [Contact Strongrate](https://www.strongrate.us/contact/): How to contact Strongrate: the message, quote and sample forms, replies within 1 business day (US Central time), and which form to use for prices, samples, technical questions and resale. - [Molded fiberglass grating](https://www.strongrate.us/molded-fiberglass-grating/): Molded fiberglass (FRP) grating from Strongrate’s Nantong factory by depth and mesh: square, rectangular and mini meshes, the four DNV-listed models with their ASTM E84 results, panel sizes, resins, surfaces and how to get factory pricing. - [Pultruded fiberglass grating](https://www.strongrate.us/pultruded-fiberglass-grating/): Strongrate pultruded fiberglass (FRP) grating: the 36 I-bar and T-bar types in the factory catalog with depth, open area and weight, the two DNV-listed models and their ASTM E84 results, resins, surfaces and how to order. - [Buying fiberglass grating direct from the factory](https://www.strongrate.us/buy-direct/): How factory-direct buying works for fiberglass grating from Nantong, China: when it fits, FOB, CIF and DDP, container orders, payment, inspection and documents, and how small or urgent orders are routed to US stock. **Request a quote:** https://www.strongrate.us/request-quote/ — Ready to price an order?
