Corrosion-resistant Moulded FRP Grating

Define the walking surface and its duty

Moulded FRP grating is a separate purchasing item from a general equipment-sourcing service. Endura describes a grid made from glass-fibre yarn and unsaturated resin, cured in a mould. Its product page identifies chemical-platform, walkway, water-treatment and maintenance uses; its oil-and-gas application page also discusses platform maintenance structures. Those descriptions establish a relevant family, not acceptance for a particular deck or a universal replacement for steel. Start the enquiry with the location and the duty the finished panel must perform.

A dimensional combination is not a load class

The Chinese product table includes a 38 mm-high grating with a 38×38 mm mesh notation and a 7/5 top/bottom rib notation. It separately includes a 50 mm-high, 38×38 mm option with 9/7 ribs. A fine-mesh entry uses the notation 38×38 (19×19) mm at 30 mm height with 7/5 ribs. The rib column does not explicitly state its unit; confirm it rather than silently assigning one. These are catalogue combinations, not named models or order codes. The source does not define whether every mesh dimension is pitch or clear opening, and does not attach a resin grade, panel length or structural load table to these examples. Preserve each complete combination.

Specify the environment before selecting the panel

For quotation, describe the process chemicals, concentrations, splash or immersion exposure, cleaning practice and temperature cycle. Ask for the resin designation and the evidence supporting that particular exposure. Where the project has fire, smoke, slip, electrical or offshore requirements, name the required test or acceptance basis instead of asking for an undefined “certified FRP” product. The manufacturer discusses platform applications, but a company application page does not certify every resin or mesh combination for that platform.

Make the load path reviewable

Provide the support layout, clear spans, bearing widths, panel orientation, openings and fixing positions. Identify distributed and concentrated loads and the deflection criterion the project designer requires. Request a load/deflection table tied to the proposed resin, height, rib geometry and support arrangement; do not estimate a span from panel height alone. Cut-outs, trimmed edges and mounting details should appear in the order-specific drawing package.

Temperature and translation limits in the reference material

The current moulded-product webpage promotes stable performance from −40 to 80°C, whereas the exhibitor description uses −50 to 120°C for a broader marine-FRP business. Neither statement is presented here as a design limit. A resin- and load-specific confirmation is needed. The English companion product table labels its first numeric dimension “Length”; the Chinese original labels it height. The dimensions above follow the Chinese table and must not be used as panel-length data. The two language pages are not independent tests.

RFQ deliverables and acceptance

A useful quotation should identify the proposed combination, panel schedule, resin and surface finish, fixing system, inspection documents and any agreed tests. Request a supplier-issued load/deflection table and calculations tied to the proposed resin, panel geometry and support arrangement. Final calculations, installation drawings and certificates can therefore remain named deliverables for the selected order. This reference makes no load guarantee, offshore approval claim, maintenance-free-life promise or commitment to supply.

Named-series load-table reference: McNICHOLS MS-S-150

McNICHOLS publishes MS-S-150 as a named moulded fiberglass-grating series. It is a separate catalogue reference, not a newly assigned Endura model and not proof that Endura makes an equivalent panel. Its official one-page load table identifies a 1.5-inch grid height, a 1.5-by-1.5-inch square grid and a product weight of 3.80 lb/ft². The square-grid notation is not relabelled as the clear opening.

The publisher calls the load-table information theoretical and intended for technically skilled evaluation. Its U rows are uniform loads in lb/ft²; C rows are concentrated loads per foot of width at mid-span. The load case, span and response must stay together. The sheet does not identify a resin grade, supplied lot or controlled order revision. Do not infer chemical resistance, an offshore/fire approval or the final installation's allowable span from these figures. Request the actual resin, bearing/support detail, cut-outs and load criteria with the RFQ.
