Company overview

This procurement profile is built for materials engineers and converters evaluating reinforcement form, sizing compatibility, package quality and downstream process stability. It organizes Changhai Co., Ltd.'s published products, processes, certificate references and official sources around the primary topic “Changhai Fiberglass roving.” The objective is to help a buyer decide whether to open a controlled RFQ, not to turn a broad company catalog into an unsupported approval.

Changhai Co., Ltd. currently lists 3 product or service groups and 1 manufacturing or support capabilities in this reviewed record. The public scope indicates what to investigate, while the buyer remains responsible for drawings, design calculations, standards, current certificates, sample approval and order-specific commercial confirmation. Claims below are attributed to the attached source set unless GetFRP explicitly labels them as qualification guidance.

SOURCE-REVIEWED PROCUREMENT PROFILE

How to evaluate Changhai Co., Ltd. for Fiberglass roving

Evaluate Changhai Co., Ltd. as a potential composite reinforcement supplier for Fiberglass roving, verify the public evidence and prepare a comparable RFQ.

Published product scope, translated into buying checks

Fiberglass roving

Changhai Co., Ltd. includes this product in its published supply scope. Treat that listing as a starting point: request the current datasheet or drawing, material and construction, available grades or dimensions, guaranteed properties, production site, quotation revision and evidence that represents the exact item offered.

Fiberglass products

For Fiberglass products, buyers should convert the catalog description into an acceptance specification. Confirm standard and custom options, raw-material system, critical tolerances, surface or finish, test basis, sample route, MOQ, lead time and packing. Any alternative proposed by Changhai Co., Ltd. should be identified explicitly rather than treated as automatically equivalent.

Chemicals

This product broadens the supplier's public portfolio, but GetFRP does not infer approval from a product name alone. Ask Changhai Co., Ltd. for the grade or model designation, manufacturing route, current technical file, production and test location, batch traceability and the limits that apply to published performance values.

Manufacturing and service capability review

Tank furnace drawing

Changhai Co., Ltd. publishes Tank furnace drawing as part of its capability scope. Buyers should ask which site and equipment perform the work, the practical size or material limits, the normal control records and whether the proposed order uses the same route. Subcontracted stages should be visible in the quality plan.

Application fit to evaluate

These are sourcing contexts suggested by the published product scope, not confirmed project references. Validate the exact application, design basis and evidence in the RFQ.

Corrosion-resistant piping and process equipment

Changhai Co., Ltd.'s public scope suggests a potential route for piping, tanks or corrosion-resistant process equipment. The RFQ should define service chemistry, temperature, pressure or stiffness class, liner, structural wall, joints, supports, nozzles, inspection and transport. Project-specific design and evidence remain necessary before the supplier can be treated as a fit.

Composite reinforcement and laminate production

Changhai Co., Ltd.'s reinforcement range can be screened for laminating, pultrusion, winding, molding or conversion programs. Buyers should confirm grade, sizing, architecture, width, tex or areal weight, package, splice and moisture limits, then run a representative processing trial before approving the material for repeat production.

Composite matrix and process-chemistry programs

Changhai Co., Ltd.'s chemistry portfolio can be evaluated for the named composite process only after the processing window and cured-property basis are aligned. Request current data sheets, grade and site identity, viscosity or mix control, cure and exotherm, storage, batch certificate fields and test evidence based on the intended reinforcement and construction.

Supplier qualification checks

Specify fiber chemistry, grade, sizing, linear density or areal weight and the intended resin and process.
Confirm roll, bobbin, pallet or tow package dimensions against the buyer's creel and handling equipment.
Set tolerance and splice limits for width, weight, moisture, fuzz, broken ends and visual defects.
Request a production-lot sample and run it under representative process speed, temperature and tension.
Link certificates of analysis to lot numbers and define retention samples and complaint traceability.
Review moisture barrier, edge protection, pallet loading and storage limits for the transport route.

Category-specific sourcing guidance

Reinforcement qualification should include processing behavior, not only finished-laminate strength. Fuzz, wet-out, tension stability, drape, stitching and package build can determine line uptime and scrap. A disciplined trial records machine settings, resin batch, environmental conditions and observed defects so a successful sample can become a repeatable incoming specification rather than an informal preference.

Published tensile strength, modulus and elongation may refer to a fiber strand, a fabric method or a cured laminate. Those values are not interchangeable. Buyers should record the test method, specimen preparation, conditioning, direction and statistical basis, then identify which values are guaranteed on the certificate of analysis and which are informational design inputs.

Supply continuity matters for high-volume reinforcement. Confirm grade-change notifications, sizing-change control, plant allocation, minimum production run, safety stock and the process for approving an alternate manufacturing line. Packaging should preserve tension and prevent moisture or edge damage throughout inland transport, ocean freight and warehouse storage.

What to include in an RFQ

  1. 1Product definition: identify the requested Fiberglass roving, drawing or grade revision, dimensions, material construction, quantity and expected annual demand.
  2. 2Performance: state the loads, environment, temperature, chemical, fire, electrical, appearance or service-life requirements that actually control selection.
  3. 3Process and source: ask whether Tank furnace drawing is performed by Changhai Co., Ltd. at the named production site and disclose subcontracted stages.
  4. 4Standards and evidence: name the required standard edition, test methods, report scope, laboratory or witness expectation and acceptance values.
  5. 5Quality plan: define the approved sample, incoming-material records, in-process controls, final inspection, sampling level, traceability and treatment of nonconforming product.
  6. 6Commercial boundary: request tooling or setup, MOQ, lead time, payment, warranty, Incoterm, export documents, packing dimensions and responsibility for transport damage as separate items.
  7. 7Change control: require written approval before changes to material, formulation, reinforcement, production site, tooling, critical process, specification or certificate status.

Evidence and review scope

Changhai Co., Ltd. does not yet have a complete official source set attached to this profile. The page can support discovery, but buyers should not rely on it for approval until the legal identity, official website and product evidence are documented.

The profile lists 1 company-published certification or test references. A listing is not the same as validation: request the complete current document, issuer, legal holder, production site, product and grade scope, standard edition, report specimen and validity date before citing it in a project or purchase order.

GetFRP last recorded a public-source review date of not recorded. Public websites and catalogs can change after review, so commercial decisions should use newly downloaded files and direct supplier confirmation. GetFRP's public or claimed status describes profile ownership and identity controls; it does not certify every product statement or predict order performance.

    Changzhou Tianma Group Co., Ltd. is based in Xinbei District, Changzhou, Jiangsu. Both the official website and China Composites Expo identify this legal entity, while the website also notes its former identity as Building Materials Factory 253. The site traces the enterprise lineage to a state-planned project begun in 1960 and calls the business the cradle of China's FRP industry; 1960 is therefore presented here as the start of the organizational lineage, not the current legal entity's registration date. The published portfolio spans glass-fiber yarns and products, unsaturated polyester and vinyl ester resins, gelcoats and auxiliaries, SMC/BMC, finished FRP products, and wind-energy and photovoltaic composites. China Composites Expo lists the exhibitor as CHANGZHOU TIANMA GROUP CO., LTD. and publishes booth 7M06 for 2026. History, industry-position, scale, capacity, market and product-performance statements are company- or organizer-published and have not been independently verified by GetFRP.
