FRP Manhole Covers & Heavy-Duty Composite Frames

Jiuding's official English export site describes the business as Jiuding New Material Co., Ltd., formerly Jiangsu Jiuding New Material Co., Ltd. The company states that it was established in 1994 and listed on the Shenzhen Stock Exchange in 2007 under stock code 002201. Its published scope covers fiberglass yarn and fabrics, grinding-wheel reinforcement materials, FRP products, pultruded profiles, gratings, flanges and custom thermoset composite components.

Techstorm Advanced Material Corporation Limited is a Shanghai-headquartered developer and manufacturer of high-performance thermoset materials and identifies itself on its official site by Shanghai Stock Exchange code 601026.SH. Its published portfolio spans wind energy, general composites, new-energy vehicles and industrial adhesives, electrical insulation, and photovoltaics. For general composites, Techstorm lists resin systems for filament-wound cylinders, cable core rods and glass- or carbon-fiber wind-blade spar-cap pultrusion, flame-retardant aircraft seating, carbon-fiber prepreg, and HP-RTM or prepreg battery covers.

Weihai Guangwei Composites Co., Ltd. (Shenzhen Stock Exchange code 300699), part of Guangwei Group, publishes an integrated chain spanning precursor, carbon fiber, fabrics, resin and prepreg through composite components, production equipment, testing and engineering. The current official site identifies operating units including Weihai Tuozhan Fiber, the General New Materials business, Guangwei Energy New Materials, Guangwei Composite Technology and Guangwei Precision Machinery. Its published portfolio covers T300- through T1100-class high-strength fibers, M40J- through M65J-class high-modulus fibers, multi-fiber prepregs, pultruded wind-blade spar caps, plates, tubes and shaped components. China Composites Expo lists the same Chinese and English entity at booth 6V01 for 2026. Identity, products and capabilities are company- or organizer-published and have not been independently site-audited by GetFRP.

Nanjing Tianming Composite Materials Co., Ltd. says on its current official website that it began in 2001 and manufactures fiberglass mats. The published product center covers chopped-strand, continuous-filament, composite, needle-punched and surface mats, together with roving, chopped glass and a TML thermoplastic composite sheet. It explicitly identifies mat constructions for vacuum infusion, pultrusion and compression molding. The China Composites Expo N directory supports the Tianming exhibitor identity and its chopped, continuous, needle and composite mat range. GetFRP assigns chopped strand mat, fiberglass mat and related fiberglass-product demand only to those actual catalog products. The site also says Tianming acts as an agent for some roving and other fiberglass products, so buyers must confirm the legal manufacturer and plant for each offered grade rather than assuming every catalog item is made on Tianming's mat lines.

Lectra Systems (Shanghai) Co., Ltd. is the Shanghai entity published on Lectra's current China contact page, at Qinzhou North Road in Xuhui. Lectra's global Vector TechTex page describes automated cutting from low- to high-ply technical materials. Q2 and iX2 explicitly cover a diverse range including carbon fibers; iQ50 and iQ80 balance production capacity and flexibility; iX6 and iX9 address hard fabrics and high-productivity cutting. The page also publishes CAD-to-cutroom automation, nesting and material optimization, sensors and connected Industry 4.0 functions. China Composites Expo's L directory lists the Shanghai exhibitor. Carbon fiber and other composites are workpiece materials handled by the equipment, not reinforcement, prepreg, sheet or finished composite products manufactured by Lectra. GetFRP therefore excludes those material-supplier keywords. Group-product scope must not be confused with the Shanghai legal entity's exact quotation, importer, installation, software, service and warranty responsibilities, which buyers should establish contractually.

Nanjing Mingfeng Composite Materials Co., Ltd. says on its official website that it was founded in 2002 and manufactures pultruded and molded fiberglass products. The current catalog explicitly lists round and rectangular tube, rod, channel, I-beam, molded and pultruded grating, insulation ladders, tool handles, epoxy fiberglass rod, guardrail, flagpole, greenhouse support and other custom products. The China Composites Expo N directory also supports the exhibitor identity and its profile, tube, grating, ladder, handle, radome and molded-part scope. GetFRP maps fiberglass grating, pultruded fiberglass profiles and fiberglass-reinforced pipe demand only to those actual catalog items. Educational articles on the site discuss broader FRP applications such as tanks, cooling towers and flues; they are not treated as proof that Mingfeng currently manufactures every discussed product.

Nanjing Haoli Hydraulic Equipment Co., Ltd. states that it was founded in 1999 and entered the composites field in 2000. Its current official catalog covers hydraulic, servo-hydraulic and caterpillar-puller pultrusion machines plus pultrusion-winding, resin-injection, automatic cut-off, mat-cutting, take-up, braided-pultrusion cable-conduit and die equipment. The China Composites Expo N directory supports the exhibitor identity and FRP pultrusion-equipment scope. Haoli sells the machinery, tooling and process support used to manufacture composite profiles. The website's statement that a machine can pull glass- or carbon-fiber sections describes compatible workpieces; it is not evidence that Haoli supplies carbon fiber, fiberglass, pultruded profiles, conduits or other finished composites. GetFRP therefore does not assign material or finished-product demand keywords to this equipment profile.

Nantong Endura Composites Co., Ltd. supplies molded fiberglass FRP grating, grating cover panels, pultruded grating and pultruded structural profiles under the Endura identity, together with pipe, tank and rotational structures made through an integrated pultrusion-and-winding route. The current official site describes glass reinforcement with unsaturated resin and places these families in chemical platforms, municipal walkways, wastewater treatment, photovoltaic maintenance, building and power applications. The China Composites Expo directory independently supports the exhibitor identity and its grating, cover, profile and engineering-service scope. GetFRP assigns only product-demand phrases that the official catalog actually supports: fiberglass and FRP grating, pultruded fiberglass profiles and fiberglass-reinforced pipe. Corrosion, load, fire, electrical or service-life performance must be checked against the selected resin, reinforcement architecture, section, thickness, span and current product-specific evidence. No establishment year, certification or approval is inferred from a website copyright line.

Glotech Electronics (Suzhou) Corp. is Glotech Industrial's Suzhou producer and seller of electronic-grade fiberglass fabrics. The current official group website says the Suzhou subsidiary was established in 2000 and took over the parent company's electronic-fiberglass-fabric business; its footer publishes a Suzhou New District address, telephone and company-domain email. China Composites Expo lists the matching Chinese and English entity. The official catalog covers standard, lightweight, ultra-thin and multilayer-laminate fiberglass cloth, publishing styles 7628, 2116, 1080, 2165, 7667, 7637, 7638, 2125, 2313 and 2113, together with electronic- and industrial-grade quartz yarn and fabric. GetFRP maps only the fiberglass and quartz-fiber scope directly supported for the Suzhou business. The group website also presents Type IV composite cylinders made by Taiwan-based Deyu Composite. That separate subsidiary's LPG, CNG and pressure-vessel scope is not assigned to Glotech Electronics (Suzhou).

Hangzhou Holycore Composite Material Co., Ltd. is a Lin'an, Hangzhou supplier of lightweight sandwich panels, honeycomb cores and CKD truck-body solutions. Its current English website publishes the Hangzhou Holycore identity, a company-stated 2012 founding, Lin'an address, telephone and company email, and describes Holycore as part of Holley Group and Wazam New Materials. China Composites Expo lists the matching Chinese and English entity, emphasizing PP honeycomb panels and finished composite parts. The current catalog covers HolyPan, UDPan, CFRT PET and XPS panels, PP honeycomb cores, FRP honeycomb, PET and XPS sandwich panels, GWT glass-fabric reinforced PP sheet, flat, embossed and anti-slip FRP sheet, decorative panels and truck-body CKD kits. GetFRP assigns measured-demand phrases such as fiberglass sheets and fiberglass panels only where a listed product explicitly has an FRP or fiberglass skin or sheet; it does not relabel every honeycomb core as a fiberglass product.

Nabertherm Ltd. (Shanghai), identified in Chinese exhibition material as Nabertherm's Shanghai industrial-furnace company, is the China sales-company entry published on the current Nabertherm website. The reviewed official navigation covers air-circulation and drying ovens, radiation-heated chamber furnaces, high-temperature solutions, protective-gas and vacuum systems, laboratory muffle and tube furnaces, debinding and sintering systems, melting and holding furnaces, custom furnace engineering and process-control documentation. The China Composites Expo N directory independently supports the Shanghai exhibitor identity. This is an equipment profile: carbon fiber, fiberglass, resin, ceramic, metal powder or any other workpiece processed in a furnace is not a material manufactured by Nabertherm. The exhibition category also is not evidence that the Shanghai entity offers composite-curing autoclaves, so GetFRP does not publish an autoclave product or inject material-product keywords.

Liaoning Yuwei Technology Co., Ltd. says on its current official website that it was founded in 2009 in Liaoyang and develops and produces specialty epoxy resins and reactive diluents. The published range explicitly covers phenoxy, hydrogenated bisphenol-A, heat-resistant multifunctional, dimer-acid-modified, brominated, halogen-free flame-retardant, crystalline and bisphenol-A liquid and solid epoxies, plus multiple glycidyl-ether diluents. Composite adhesive and reinforcement material is one published application. China Composites Expo's L directory retains the legacy exhibitor name Liaoyang Xinyu Chemical Co., Ltd. The domain and business range provide a research trail, but the current website does not publish a legal name-change or succession document. GetFRP therefore builds the profile for the current Yuwei entity and does not state that the two names are a proven identical legal person. Capacity, patent, management-system and performance statements are company-published; certification fields remain empty until current certificates are matched to entity, site, scope and validity.

Lianyungang Weide Composite Materials Facilities Co., Ltd. says on its current official website that it was established in 2001 and develops and manufactures composite-production equipment. The published range covers continuous-filament-winding FRP pipe lines, high-pressure hydrogen-cylinder winding lines, four-axis and horizontal winding machines, high-pressure epoxy-pipe lines, centrifugal-casting GRP pipe lines, lighting-pole lines and supporting manipulators, curing ovens, resin-supply, intelligent feeding, conveying, joint-making and quality-assurance systems. China Composites Expo's L directory lists the matching exhibitor. Weide sells the machinery used to make pipes, cylinders and poles; those outputs are not presented as Weide-manufactured FRP or carbon-fiber products. GetFRP therefore excludes reinforcement, FRP-pipe and finished-cylinder supplier keywords. Capacity, performance, import-substitution, service-life and mechanical-property statements are supplier claims that must be validated against the quoted configuration, representative trials, FAT, SAT and contractual acceptance records.

Changzhou Rixin Molding Technology Co., Ltd. is based in Zhulin, Jintan District, Changzhou, Jiangsu. Its official website says the company was founded in 2009 and develops, manufactures and sells SMC/BMC compounds and compression-molded parts. It also designs SMC production lines and provides integrated SMC/BMC technical services. Published applications include automotive, building materials, sanitary products, rail, agriculture, marine equipment, electric power, water infrastructure and new energy. The China Composites Expo lists the company as CHANGZHOU RIXIN SMC/BMC CO., LTD., while the Rixin Group English site uses Changzhou Rixin Molding Technology Co., Ltd. This is a standalone legal-company profile, separate from GetFRP's Changzhou Rixin Group exhibitor profile. Capacity, equipment, qualification and customer-validation statements are company- or organizer-published and have not been independently verified by GetFRP.

Ningbo Haigela New Material Technology Co., Ltd. publishes liquid-crystal-polyarylate (LCP) fiber and converted materials under the Higlar identity. Its current official product directory covers high-strength filament, chopped fiber, monofilament, ply-twisted or twisted yarn, colored, low-dielectric, multicomponent, soft and high-elasticity LCP variants, together with fabric, short-fiber paper and pulp paper. Individual pages expose HT and MF grade families rather than one interchangeable commodity. The China Composites Expo N directory independently lists the Ningbo exhibitor. The official Chinese and English company pages give inconsistent 2017 and 2018 establishment dates, so GetFRP leaves the field blank. Published references to 5G, robot cable, aerospace, radomes, protective clothing and sports fabrics describe possible applications; they do not prove that Haigela manufactures every downstream cable, radome, garment or sporting product.

Diab Technology (Changshu) Co., Ltd. is the Jiangsu, China entity currently identified in the footer and contact information throughout Diab's Chinese website. The official portfolio covers Divinycell PVC, PET, PES and PEI foam cores, ProBalsa balsa, finishing, pre-cut kits and composite consulting. China Composites Expo lists the matching entity as DIAB TECHNOLOGY (CHANGSHU) CO., LTD. under foam core, balsa and sandwich panels. Diab's long group history, worldwide sites and application references do not automatically establish the Changshu entity's incorporation date, capacity or individual delivery record. This profile therefore leaves the establishment year empty and does not transfer every group approval to the Changshu company. Product and performance information still requires grade-, thickness-, finish- and manufacturing-site-specific verification.

Nabaltec (Shanghai) Trading Co., Ltd. is the Shanghai trading company explicitly listed on Nabaltec's current official company page. The reviewed group catalog covers APYRAL ground, fine-precipitated, viscosity-optimized and surface-treated aluminum hydroxides for environmentally oriented flame-retardant systems; APYRAL AOH and ACTILOX boehmite functional fillers; NABALOX calcined, reactive, thermally conductive and high-purity aluminas; and GRANALOX spray-dried ceramic bodies. The China Composites Expo N directory independently supports the Shanghai exhibitor identity and functional-filler scope. GetFRP presents the Shanghai entity as a China sales, trading and technical-document interface. Production plants, capacity, management systems, certificates, R&D assets and guaranteed properties published for Nabaltec AG or other group sites are not automatically attributed to this Shanghai legal entity. Likewise, a filler's suitability for cable compounds, printed-circuit boards, thermoplastics, thermosets or ceramics does not mean that the Shanghai company manufactures those downstream composite products.

Zhejiang Huafeng New Material Co., Ltd. states on its official English website that it has developed, manufactured and sold new piping materials since 1998 and is headquartered in Hangzhou, Zhejiang. Its published range includes continuously wound GRP mortar and pressure pipe, GRP jacking pipe, water-supply, drainage and sewer pipe, FRP ductwork, flanges, tees, elbows, sleeves and manholes, plus communication and power cable protection pipe for municipal water, water infrastructure, petrochemical, marine and trenchless projects.
