pultrx | Fiberglass I beam Product: https://pultrx.com/frp-profiles/fiberglass-i-beam Updated: 2026-10-22 Contact: inquiry@pultrx.com A fiberglass I beam is a composite section with two flanges joined by a central web. Its overall depth and flange width describe the envelope, while web thickness, flange thickness and root geometry complete the section. FRP or GRP I-beam procurement also requires the installed span, restraints and connection details; a catalogue dimension is not a load rating. Product family: https://pultrx.com/frp-profiles/structural-profiles Manufacturer: Henan Zhongsheng Composite Material Co., Ltd. Export partner: pultrx, Shanghai, China Catalogue figures are references, not a binding offer. Confirm the configuration, inclusions and acceptance criteria in the written quotation. TBD means not confirmed, never zero. CONFIGURATIONS Configuration SPECIFICATIONS Catalogue examples: width × height: Configuration = 1½ × 3, 2 × 4 and 3 × 6 inches with listed wall ¼ inch; 4 × 8 inches with listed wall ⅜ inch (Source examples only; confirm web/flange thickness separately. Neither stock availability nor a full capability range is established.) Quoted section tolerances and material: Configuration = TBD — ask factory Allowable loads and deflection criteria: Configuration = TBD — ask factory Minimum order and production lead time: Configuration = TBD — ask factory SOURCE Henan Zhongsheng — I-beam dimensional examples: https://www.frpzs.com/FRP-Profiles/FRP-Structural-Profiles/Fiberglass-I-Beam.html Henan Zhongsheng I-beam catalogue reviewed 2026-10-22. Width × height ordering retained; examples do not establish project suitability. SELECTION - Which dimension is the depth?: Label overall depth and flange width on the drawing. Keep web and flange thickness separate even when a catalogue uses one wall value; include root radii and hole locations. - What controls the span?: Provide support positions, load locations, restraint and allowable deflection. Identify sustained or moving loads so the designer can request suitable material evidence and assess service behavior. - How does force enter the beam?: Show bearing lengths, support plates and bolted joints. Local bearing and connection checks need their own details; an overall bending assessment does not by itself settle these interfaces. Keep section identification and structural acceptance separate | Review item | Required project input | | --- | --- | | Section geometry | Depth, flange width, web/flange thickness, radii and orientation. | | Deflection and stability | Span, loads, service limits and restraint arrangement. | | Local bearing and joints | Contact lengths, plates, holes and connection load paths. | The listed inch dimensions are catalogue examples, not an allowable-span table. Strongwell explains that pultruded members have directional properties and that structural assessment must consider stiffness. Its EXTREN properties belong to that product system and are not adopted here. Request evidence for the offered Zhongsheng material, then have the project designer assess the actual beam and connections.

PRODUCT FORMS AND CATALOGUE EXAMPLES - Pultruded I sections with drawing-confirmed web and flanges APPLICATIONS TO REVIEW - Frame and support members subject to project engineering review PROCESS TO REVIEW - Submit geometry and design inputs: Provide the beam schedule, installation sketch and support details with environmental requirements. - Review the offer: Confirm the section, material evidence and engineering responsibilities before accepting a proposed substitution. - Agree production acceptance: Set dimensional checks, required reports, payment, delivery and conformity responsibility in the quotation. CORE SCOPE TO SPECIFY - Finished beams to the accepted section and length schedule - Agreed inspection documents and shipment identification OPTIONS AND SERVICES TO PRICE SEPARATELY - Connection plates, drilling, special cuts and assembly - Engineering, project tests, samples, tooling and freight RFQ INPUTS — complete these before requesting a quotation - Depth, flange width, both thicknesses and cut quantities - Span, restraint, loading and deflection limits - Bearing surfaces, joints and hole drawings - Service environment, finish and documentation requirements ACCEPTANCE EVIDENCE TO AGREE - Measure depth, width, web and flange thickness against the approved drawing. - Check straightness, cut length and holes using agreed methods. - Review lot traceability and contracted material evidence separately from project design approval. 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 Can I select this beam from a steel span table? No. Use an engineering assessment based on the offered composite material, geometry and actual support conditions. Are the example sizes available from stock? Stock is unconfirmed. Request written availability, minimum quantity and lead time for the selected drawing and material.
