pultrx | Fiberglass grating Product: https://pultrx.com/frp-profiles/fiberglass-grating Updated: 2026-11-01 Contact: inquiry@pultrx.com Fiberglass grating is an open composite flooring or platform component. The manufacturer lists molded grating, pultruded grating and stair treads. The selected construction, panel orientation and supporting structure must match the intended use. Request the applicable span and load evidence for the quoted panel rather than relying on a generic family claim. Manufacturer: Henan Zhongsheng Composite Material Co., Ltd. Manufacturer’s export trading company: pultrx, Shanghai, China Catalogue figures are references, not a binding offer. Confirm the configuration, inclusions and acceptance criteria in the written quotation. CONFIGURATIONS Configuration SPECIFICATIONS Dimension convention: Configuration = Panel length × width × depth, opening dimensions and bearing direction; declare units. Pultruded I-bar example heights: Configuration = 25.4 mm and 38.1 mm Pultruded T-bar example height: Configuration = 50.8 mm Pultruded panel catalogue examples: Configuration = 915 × 6,100 mm for I25; 1,220 × 6,100 mm for I38 and T50 (Dimensions describe listed pultruded configurations; no panel load rating is adopted.) PRODUCT PHOTOGRAPHS - Pultruded grating example. Mark the load-bar direction and supports on the panel layout; compare other forms below. Image: https://pultrx.com/images/frp-profiles/pultruded-fiberglass-grating.webp SELECTION - Provide the support plan: Mark support spacing, bearing edges and cutouts. Identify the loading direction for the proposed panel. - Specify the walking surface: Describe footwear, liquids and cleaning conditions. Ask for a finish proposal and any required slip or fire test evidence. Compare grating construction and bearing direction Identify splash, immersion or vapor exposure, cleaning chemicals and operating temperatures. Request evidence for the quoted panel material and surface system alongside the load and layout review. Define the grating service environment and resin evidence (/guides/frp-resin-selection) A molded panel is an integral grid. Pultruded grating assembles bearing bars and cross members, with the bearing bars oriented across the intended span. Square-mesh molded products can provide bearing in two directions; rectangular molded products need a separate direction check. These construction distinctions are documented in the references below, but each quotation must identify the actual panel and applicable load data. | Comparison | Requirement to confirm | | --- | --- | | Equal panel depth | Depth alone does not establish equal capacity or deflection. Compare the exact bar or grid geometry, material and load data. | | Mesh size | Distinguish center-to-center pitch from clear opening. Identify which dimension the project limits. | | Panel layout | Show bearing direction, supports, cutouts and edge support; match the load-table assumptions. | | Service conditions | State chemicals, temperature, outdoor exposure and required surface or qualification evidence. | Use the selection guide to prepare a panel schedule and compare quotations on the same basis.

PRODUCT FORMS AND CATALOGUE EXAMPLES - Molded grating: separate panel specification - Pultruded I-bar grating: 25.4 or 38.1 mm height examples - Pultruded T-bar grating: 50.8 mm height example - Grating stair treads APPLICATIONS TO REVIEW - Industrial walkways - Access platforms and stairs subject to design approval PROCESS TO REVIEW - Review panel layout: Agree panel marks, openings, orientation and cutouts. - Confirm product selection: Review material, finish and project performance documentation. - Set inspection scope: Agree dimensional, appearance and any load-test requirements. - Verify shipment completeness: Check panel labels, accessory quantities and packing records. CORE SCOPE TO SPECIFY - Profile quantities, dimensions and cut lengths identified in the accepted quotation - Packaging, lot identification and inspection documents as agreed OPTIONS AND SERVICES TO PRICE SEPARATELY - Special machining, project testing and samples: confirm charges - Freight and any custom tooling: itemize if required RFQ INPUTS — complete these before requesting a quotation - Panel layout and support spacing - Panel dimensions, openings and cutouts - Loads and permitted deflection from the designer - Chemical, temperature and surface requirements - Clips, nosing or edge-treatment requirements - Quantities, delivery location and date ACCEPTANCE EVIDENCE TO AGREE - Check panel size, depth and opening geometry. - Verify bearing direction and marked panel positions. - Inspect cut edges, surface finish and visible damage. - Reconcile clips and any contracted performance reports. COMMERCIAL ITEMS TO CONFIRM Applicable performance and destination requirements; lead time in working days; payment milestones; warranty party, term and exclusions; packing, Incoterm and delivery destination. For equipment, include plant power and spare parts. QUESTIONS Are molded and pultruded grating interchangeable? Treat them as separate product proposals. Review support direction, geometry and documented performance for the intended arrangement. Are fixing clips supplied? State the support material and fixing requirement. Clip type, quantity and inclusion must be confirmed in the quotation.
