pultrx | FRP structural profiles Product: https://pultrx.com/frp-profiles/structural-profiles Updated: 2026-11-07 Contact: inquiry@pultrx.com FRP structural profiles are shaped composite members used as components in engineered assemblies. The manufacturer lists I-beams, channels, angles and T-profiles. Section geometry is only part of selection: specify the required material properties, loading direction, environmental exposure and connection design before accepting a section for the project. 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 = Depth × width with web/flange thicknesses, radii and cut length. Specify units. I-beam catalogue examples: width × height: Configuration = 1½ × 3, 2 × 4 and 3 × 6 in; listed wall ¼ in Larger I-beam catalogue example: Configuration = 4 × 8 in width × height; listed wall ⅜ in PRODUCT REQUIREMENTS For structural pultruded profiles, specify EN 13706-2 test methods and general requirements, together with the required E17 or E23 grade under EN 13706-3. The quotation defines the agreed grade, dimensional tolerances and supporting test reports for the ordered profile. PRODUCT PHOTOGRAPHS - Assortment of standard sections. Image: https://pultrx.com/images/frp-profiles/fiberglass-profile-assortment.webp SELECTION - Define the engineering basis: Provide span, supports and load cases to the responsible designer. Request product data tied to the quoted material. - Check the connections: Identify bolt holes, bearing faces and mating sections. Agree machining tolerances separately from overall section tolerances. Match the section drawing with structural evidence Document chemical and outdoor exposure together with sustained loads and project test requirements. Ask the reviewer to assess the proposed material evidence under the stated service conditions. Review resin selection alongside structural requirements (/guides/frp-resin-selection) The outside shape of an FRP angle, channel or beam does not establish its structural properties. Reinforcement direction and the proposed material system matter. Matching a steel section envelope or another supplier’s drawing is not evidence of equivalent strength, stiffness or connection behavior. | Design question | Evidence to request | | --- | --- | | Will the section carry the load? | Properties applicable to the ordered section and material, with the load case, supports and design method identified. | | Will deflection be acceptable? | A calculation or applicable table including the relevant bending and shear effects; a strength value alone does not answer this. | | Will connections and supports work? | Connection geometry, bearing areas, holes, bracing and load-transfer details reviewed for the intended installation. | Manufacturer design guides such as the references below explain why direction, deflection and support assumptions need separate review. Their numerical properties and load tables apply to their own systems. Request the corresponding evidence for the Zhongsheng section proposed in the quotation; the catalogue form list is not a structural design approval. Keep the drawing revision, quantities, required evidence and approval owner in the order schedule. Add structural requirements to the FRP profile RFQ (/guides/frp-profile-rfq-checklist) TECHNICAL REFERENCES - Strongwell: introduction to EXTREN structural shapes: https://www.strongwell.com/wp-content/uploads/2015/05/Introduction-To-Extren.pdf — Supports general distinctions between directional structural properties, deflection and pressure service.

PRODUCT FORMS AND CATALOGUE EXAMPLES - I-beams: 1½ × 3, 2 × 4, 3 × 6 and 4 × 8 in width × height examples - Channels - Angles - T-sections APPLICATIONS TO REVIEW - Industrial framing components - Platform and railing components subject to design review PROCESS TO REVIEW - Review the member schedule: Confirm drawings, lengths, quantities and critical interfaces. - Review qualification evidence: Agree the material data and any project testing needed. - Approve fabrication scope: Record holes, cuts, finish and inspection requirements. - Check the shipment: Compare identification and inspection documents with the order. 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 - Section drawings and member schedule - Lengths and quantities by member mark - Design requirements and required test methods - Hole, cut and connection drawings - Exposure, finish and color requirements - Destination and delivery sequence ACCEPTANCE EVIDENCE TO AGREE - Measure flange, web and overall section dimensions. - Check length, hole locations and specified straightness. - Verify identification against the member schedule. - Review agreed material and test documentation. 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 a steel section be replaced by matching dimensions? Matching dimensions alone do not establish equivalent behavior. Have the project designer assess stiffness, strength and connections using the proposed FRP data. Are structural grades certified? No certification is assumed here. Specify the required grade, test basis and documentary evidence in the RFQ.
