F1 COMPOSITE - FRP GRATING GUIDE SPECIFICATION (EDITABLE TEMPLATE) Revision: 2026-10-23 Source page: https://www.f1composite.com/resources/blog/frp-grating-specification-guide HOW TO USE THIS TEMPLATE - Text in [square brackets] is a project value or an option. Replace it or delete the line. - Loads, deflection limits, fire performance and slip requirements come from the governing code, the owner's standard and the engineer of record. This template does not set them. - Delete the paragraphs that do not apply (for example, molded or pultruded grating). - Section number: manufacturers commonly use MasterFormat 06 74 13 (Fiberglass Reinforced Gratings). US Department of Defense projects use UFGS 06 73 01. Use the number your project manual requires. ====================================================================================== SECTION [06 74 13] - FIBERGLASS REINFORCED PLASTIC (FRP) GRATING ====================================================================================== PART 1 - GENERAL 1.1 SUMMARY A.

Fire performance: [flame spread index of 25 or less per ASTM E84] [other], tested on the offered resin system. [Delete if not required.] C. Walking surface: [grit] [meniscus] [concave] [smooth]; slip evidence for the [wet / oily / contaminated] condition to [standard]. D. Electrical: [state any non-conductive requirement; note that metal clips and fasteners are part of the assembly]. 1.5 SUBMITTALS A. Product data: panel series, resin, glass content basis, surface, color and weight per unit area. B. Load tables for each panel type and span, with the test or calculation basis. C. Shop drawings: panel layout, bearing-bar direction (pultruded), cut-outs, banding, support details, clip types, clip locations and quantities. D. Test reports: fire [ASTM E84], slip [standard], and any chemical resistance data, each naming the tested product, report number and date. E. Samples: [___ in x ___ in] panel sample showing color and surface. F. Installation instructions, including cutting, cut-edge sealing and clip spacing. 1.6 QUALITY ASSURANCE A. Manufacturer quality system: [ISO 9001 certificate with scope and holder name]. B. Each shipment labeled with panel mark, series and lot, matching the shop drawings. 1.7 DELIVERY, STORAGE AND HANDLING A. Store panels flat on level supports, protected from impact and prolonged sunlight as the manufacturer instructs. PART 2 - PRODUCTS 2.1 MOLDED FRP GRATING [delete if not used] A. Construction: one-piece molded panel with continuous glass reinforcement in both directions. B. Depth: [___ in / mm]. Mesh: [square ___ x ___] [mini-mesh] [rectangular]. C. Top surface: [grit] [meniscus] [covered / solid top]. D. Color: [___]. UV inhibitor in the resin. 2.2 PULTRUDED FRP GRATING [delete if not used] A. Construction: pultruded bearing bars [T] [I] [HI] joined by cross rods or cross bars. B. Bearing bar depth: [___ in / mm]. Open area: [___ %]. C. Bearing bars span between supports as shown on the shop drawings. D. Top surface: [grit] [smooth]. Color: [___]. 2.3 STAIR TREADS AND COVERS [delete if not used] A. Treads: [molded] [pultruded], with nosing [color ___] and end plates for [bolting to stringers]. B. Tread covers: [thickness, nosing, grit], fastened to [existing tread type]. 2.4 ACCESSORIES A. Hold-down clips and panel connectors: [316 stainless steel] [other], types selected for the panel series, bar geometry and support detail. B. Fasteners: [material and grade]. C. Sealing resin: compatible with the panel resin, supplied by the grating manufacturer. 2.5 FABRICATION A. Cut panels to the shop drawings. Seal every cut surface with the compatible resin. B. Band openings and edges where shown, by [method]. C. Tolerances: [panel size, squareness and flatness tolerances]. PART 3 - EXECUTION 3.1 EXAMINATION A. Verify that supports are level and coplanar and give at least [1.5 in / 38 mm] bearing, or the bearing shown on the shop drawings. 3.2 INSTALLATION A. Install panels with bearing bars spanning between supports (pultruded grating). B. Fasten each panel with at least [four] hold-downs, at least [two] on each support line, at no more than [4 ft / 1,200 mm] spacing, or as shown on the shop drawings. C. Field cuts: use carbide or diamond tools with dust extraction; support cut ends; seal every cut surface; recheck clip layout after cutting. 3.3 FIELD QUALITY CONTROL A. Inspect panel orientation, bearing, clip count and spacing, sealed cut edges, gaps and trip edges before handover.
