Fiberglass sheets & FRP plate, cut to size

The pultruded flat-sheet program typically runs 2–25 mm thick in panel widths up to about 1,000–1,220 mm, supplied cut to your part sizes rather than as fixed stock panels. Narrow solid sections up to 305×25 mm are a separate, catalogued product — see the fiberglass flat bar page with published sizes and weights. State the finished part dimensions and quantity in the RFQ; nesting and cutting are done in production.

Commercially they are the same family: 'fiberglass sheet' usually means the thinner end (2–6 mm — liners, covers, kick panels), 'FRP plate' or 'structural plate' the thicker end (10–25 mm — gusset plates, base plates, wear pads). Both are E-glass laminates in a polyester or vinyl ester matrix; the thicker plates carry more multidirectional reinforcement so bolted connections load evenly.

Yes — the gritted variant bonds a silica or aluminum-oxide grit surface to one face, which is exactly the material used for our stair tread covers and solid-top walkway plate. Smooth (veiled) both faces is standard for liners, baffles, and electrical applications; embossed and pigmented options are available per order.

Gusset and splice plates in FRP structures (bolted with the same 316 SS hardware as the profiles), tank and clarifier baffles, wear pads and bearing strips between FRP and steel, equipment covers and kick panels, trench and drain covers in gritted plate, and cut blanks that fabricators machine into brackets and spacers. In corrosive service it replaces coated steel plate; in electrical rooms it replaces conductive metal panels.

Isophthalic polyester is the general-purpose default. Move to vinyl ester for acid, caustic, hypochlorite, and marine immersion — tank internals and wastewater baffles are the classic cases. Fire-retardant polyester (the ASTM E84 Class 1 family) covers escape routes and enclosed spaces; UV-stabilized systems with surface veil are the right call for outdoor exposure.

Sheet laminates are built on the same E-glass / resin systems as our profiles, and orders ship with batch mechanical certificates on request. Because sheet reinforcement is tailored per thickness and duty (more multidirectional glass than a unidirectional profile), we quote the laminate spec per order rather than publishing one generic table — send the load case and we return the laminate build-up with the quotation.
