Henan Zhongsheng lists radome profiles and ladder rungs among its custom products. These examples identify product forms, not universal radio-frequency, electrical or structural qualifications. Provide the operating requirements so the proposed section and material can be reviewed together. 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 = Controlled cross-section drawing plus length, holes and mating dimensions; label mm or inches. Catalogue form examples: Configuration = Radome / antenna-cover profiles and ladder-rung profiles 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 - Custom hollow section with internal webs on a factory line.

Image: https://pultrx.com/images/frp-profiles/phenolic-fiberglass-profiles.webp SELECTION - State the functional requirements: For a radome, define the required RF assessment; for a rung, identify assembly and test requirements. Ask for applicable evidence. - Control design changes: Assign drawing revisions and agree sample approval, tooling charges and rights to supplied design files. PRODUCT FORMS AND CATALOGUE EXAMPLES - Radome and antenna-cover profiles - Ladder-rung profiles APPLICATIONS TO REVIEW - Antenna-cover components - Ladder components requiring assembly qualification PROCESS TO REVIEW - Review the design package: Define geometry, function and critical interfaces. - Agree the technical proposal: Confirm material, finish, secondary operations and qualification scope. - Approve sample criteria: Set dimensional and functional checks before production authorization. - Review production delivery: Match parts, revisions and agreed records to the accepted 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 - Controlled drawing and mating-part details - Service environment and functional requirements - Quantity, lengths and secondary operations - Material, color and surface preferences - Sample approval and project testing requirements - Delivery date, destination and packaging needs ACCEPTANCE EVIDENCE TO AGREE - Verify drawing revision and critical dimensions. - Check nominated mating parts and mounting features. - Inspect appearance against an approved reference. - Review contracted functional tests and lot records. 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 Is a new die required for every order? The factory must assess the drawing and available tooling. Any tooling cost and ownership terms should appear separately in the offer. Does a ladder-rung listing certify a finished ladder? No. Component supply does not establish assembly certification. Agree the product and assembly testing responsibilities for your project.
