Compare Chinese manufacturers of molded and pultruded FRP grating by resin system, panel geometry, fire performance, public company profile and production cluster.
| Field | Typical range | Sourcing note |
|---|---|---|
| Process | Molded or pultruded | Do not treat the two constructions as interchangeable in structural checks. |
| Panel depth | 25 / 30 / 38 / 50 mm | Confirm finished depth, tolerance and support span. |
| Mesh | 38 × 38 mm and micro-mesh options | State clear opening and accessibility requirement. |
| Resin | Ortho / iso / vinyl ester / phenolic | Match the resin to chemical and fire exposure. |
| Surface | Concave / grit / covered / conductive | Specify slip, cleaning and static-control needs. |
| Evidence | Load table, fire report, resin certificate, MTC | Require report numbers and scope before approval. |
China’s FRP grating supply base covers molded panels, pultruded load-bearing panels, stair treads, trench covers and custom-cut assemblies. The first sourcing decision is not factory size but service condition: orthophthalic polyester is common for general industrial walkways, isophthalic systems improve chemical resistance, vinyl ester is selected for aggressive process environments, and phenolic systems are considered when smoke and flame performance dominate. A useful RFQ therefore names the resin family, load case, support span, surface treatment and destination standard instead of asking only for a panel price.
Export-ready factories differ most in their control of glass content, cure, bar geometry, dimensional tolerance and traceability. For molded grating, buyers should confirm mesh pattern, overall depth, load-bar thickness and whether the quoted size is the nominal mold size or the finished cut panel. For pultruded grating, confirm bearing-bar pitch, cross-rod construction and the test basis for published load tables. CE documents, ISO 9001 certificates and test reports should always be checked for the legal entity, product scope and validity date rather than accepted as logo files.
GetFRP exposes public company profiles and capability evidence for first-pass comparison. A procurement team can compare documented process, relevant certifications, production region, scale tier and the ability to supply the requested resin and surface before contacting a factory. Once the specification is stable, the sourcing desk can request matched samples, confirm current test evidence and arrange pre-shipment inspection against the same acceptance criteria used in the RFQ.
Every card is an explicit supplier-product relationship. Verification applies to the recorded capability and evidence state, not a blanket certification of every specification.

No. EN 13706 is a specification for pultruded profiles and includes designation, test methods and mechanical property classes. It is not a universal fire classification for grating. Ask for the product-specific fire or smoke report required by the project, identify the tested resin and construction, and verify that the reported specimen represents the offered panel.
Molded grating provides two-directional continuity, flexible cutting and broad corrosion-resistant resin choices. Pultruded grating is usually selected when high unidirectional stiffness, longer spans or repeatable load-bar geometry matter. The correct choice depends on span, load, cut-outs, chemical exposure and deflection limit—not headline price per square metre.
Include process type, panel and mesh dimensions, resin, colour, surface, design load, support span, deflection limit, fire or smoke requirement, cut plan, clips, quantity, packaging, destination and Incoterm. Ask the supplier to identify deviations explicitly and attach current test evidence.
The shortlist is screened for legal identity, manufacturing process, relevant product capability, certification scope, scale tier and export readiness. Before an order, documents are rechecked for validity and the inspection plan is tied to the approved specification, sample and acceptance criteria.
