Changzhou Pro-Tech Industry is a source-reviewed supplier profile for fiberglass cloth, with every search topic tied to company-published product or process evidence and separated from buyer-side verification requirements.
Changzhou Pro-Tech Industry Co., Ltd., the English trading name used by Changzhou Putai Fiberglass Products Co., Ltd., is based in Changzhou, Jiangsu. Its current Chinese and English websites say the company was established in 2007 to manufacture industrial fabrics from glass, carbon, aramid, basalt and hybrid fibers; the Chinese profile separately traces the team's composite-material activity to 1995. The published catalog spans woven and multiaxial fabrics, combination and core mats, 3D fabrics, flow mesh and carbon-fiber textiles. The company reports annual output above 20,000 tonnes and business relationships in more than 30 countries and regions. These history, capacity and market-coverage statements are company-published and have not been independently verified by GetFRP.
The reviewed product and process scope makes this supplier relevant to buyer searches for fiberglass cloth. These phrases describe products or processes supported by the cited public scope; they do not expand the supplier's catalog or replace technical qualification.

This procurement profile is built for materials engineers and converters evaluating reinforcement form, sizing compatibility, package quality and downstream process stability. It organizes Changzhou Pro-Tech Industry Co., Ltd.'s published products, processes, certificate references and official sources around the primary topic “Changzhou Pro-Tech Industry Fiberglass woven roving and woven fabrics.” 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.
Changzhou Pro-Tech Industry Co., Ltd. currently lists 8 product or service groups and 6 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.
Putai's official directory lists 0°/90° and ±45° biaxials, triaxials, quadraxials, unidirectionals, woven-roving combination mat, stitched chopped-strand mat, core combination mat, 3D hollow woven fabric, fiberglass flow mesh, and carbon woven, multiaxial, unidirectional and spread-tow fabrics. The expo profile additionally identifies jumbo-width combination fabrics and knitted mat for polyurethane pultrusion, with applications in marine craft, rail, automotive, tanks, trenchless pipe rehabilitation, wind energy and sports. Some individual product pages publish areal weights, fiber orientations, standard or maximum widths and packaging examples, but these values must not be generalized across the portfolio. Buyers should qualify the exact grade's legal manufacturer and production site; fiber brand, grade and sizing; warp, weft or directional areal weights and tolerances; chopped and core layer construction; stitching yarn and gauge; width and roll length; resin compatibility; wet-out or flow behavior; mechanical properties; test methods; lot CoA; current TDS; packaging; MOQ; lead time; and current ISO 9001 certificate.
Evaluate Changzhou Pro-Tech Industry Co., Ltd. as a potential composite reinforcement supplier for fiberglass cloth, verify the public evidence and prepare a comparable RFQ.
Changzhou Pro-Tech Industry 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.
For Unidirectional, biaxial, triaxial and quadraxial stitched fabrics, 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 Changzhou Pro-Tech Industry Co., Ltd. should be identified explicitly rather than treated as automatically equivalent.
This product broadens the supplier's public portfolio, but GetFRP does not infer approval from a product name alone. Ask Changzhou Pro-Tech Industry 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.
A useful RFQ for 3D sandwich woven fabrics and biaxial core complexes should describe the buyer's application without disclosing unnecessary proprietary detail, then state the measurable product requirements. Compare Changzhou Pro-Tech Industry Co., Ltd.'s response against the same dimensions, quantity, inspection, documentation, Incoterm and delivery assumptions used for every shortlisted supplier.
Changzhou Pro-Tech Industry Co., Ltd. publishes Weaving of glass, carbon, aramid, basalt and hybrid fibers 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.
The relevance of Unidirectional and multiaxial warp stitching depends on the requested product and acceptance criteria. During qualification, request a process flow, critical control points, inspection or test method, operator or equipment qualification where applicable, nonconformance handling and a recent example that represents the offered production route.
For sourcing purposes, Stitch bonding of chopped layers, woven rovings and core layers is a capability signal rather than independent verification. Confirm capacity, tooling or fixture availability, setup and changeover assumptions, lot definition, sample approval and traceability. The quotation should identify any limitation that could affect geometry, performance, appearance or delivery.
Buyers evaluating 3D hollow and sandwich-fabric manufacture should connect the process claim to evidence: an equipment list, controlled procedure, representative report, production photograph or witnessed sample may each answer a different risk. Changzhou Pro-Tech Industry Co., Ltd. should also explain how the result is checked before release and recorded for the shipment.
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.
Changzhou Pro-Tech Industry 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.
Changzhou Pro-Tech Industry 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.
Changzhou Pro-Tech Industry Co., Ltd.'s listed products may be relevant to lightweight consumer-electronics parts. Buyers should define cosmetic standards, fiber orientation, resin and coating, radio or thermal requirements, tool and color approval, dimensional gauges, drop or durability tests, assembly interfaces, high-volume process controls and intellectual-property boundaries.
Changzhou Pro-Tech Industry Co., Ltd.'s source record currently includes Changzhou Pro-Tech Official Website, Changzhou Putai Company Profile, Changzhou Putai Product Directory, China Composites Expo Exhibitor Profile. These links let a buyer distinguish company-published information from GetFRP's own qualification guidance and return to the original context when a claim changes.
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 2026-08-13. 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.
