Nanjing Spare Composites is a source-reviewed supplier profile for fiberglass rebar, fiberglass panels, and fiberglass grating, with every search topic tied to company-published product or process evidence and separated from buyer-side verification requirements.
SPARE's Chinese website presents the business as Nanjing Spare New Materials Co., Ltd., while its official English export site operates under the Nanjing Spare Composites brand and names Nanjing Spare Composites Yizheng Co., Ltd. in the site footer. The company's published history says Nanjing Spare was founded in May 1995 and the Yizheng company was established in 2011. Its public product scope centers on pultruded glass-fiber composite profiles, gratings, bridge and infrastructure components, with custom development, machining, testing and installation support.
The reviewed product and process scope makes this supplier relevant to buyer searches for fiberglass rebar, fiberglass panels, fiberglass grating, and pultruded. 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 engineering and procurement teams comparing a finished FRP or composite component against a controlled drawing, service condition and inspection plan. It organizes Nanjing Spare Composites's published products, processes, certificate references and official sources around the primary topic “Nanjing Spare Composites Pultruded FRP Profiles.” 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.
Nanjing Spare Composites currently lists 6 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.
SPARE's official catalogs cover standard and custom pultruded profiles; pultruded and molded grating; bridge components; ladder rails; tool handles; epoxy pultrusions; connectors; covers; cooling-tower structures; handrails and fencing; window and door profiles; rebar and wall cladding; solar-panel frames; cable trays; and vehicle composite profiles. The Chinese company profile states that its Nanjing and Yizheng facilities total about 47,000 m², employ around 300 people including more than 40 technical staff, operate more than 40 pultrusion lines and have annual processing capacity of about 10,000 tonnes. The English site describes almost 50 pultrusion lines plus molding, injection molding, secondary machining, automated paint finishing, independent inspection and R&D centers. Because the two official sites differ on line count and operating-entity wording, buyers should confirm the contracting entity, current capacity, resin system, fire and load data, dimensional tolerances, certification scope, MOQ, lead time and batch traceability during RFQ, sample approval and factory audit.
Evaluate Nanjing Spare Composites as a potential composite product manufacturer for fiberglass rebar, verify the public evidence and prepare a comparable RFQ.
Nanjing Spare Composites 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 Pultruded and molded FRP grating, decking and covers, 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 Nanjing Spare Composites 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 Nanjing Spare Composites 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 FRP handrails, fencing, ladder rails, tool handles, and window and door profiles should describe the buyer's application without disclosing unnecessary proprietary detail, then state the measurable product requirements. Compare Nanjing Spare Composites's response against the same dimensions, quantity, inspection, documentation, Incoterm and delivery assumptions used for every shortlisted supplier.
Nanjing Spare Composites publishes Continuous FRP pultrusion 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 Molding and injection-molding equipment 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, Custom-profile engineering, tooling and product development 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 Secondary machining and automated spray finishing 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. Nanjing Spare Composites 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.
Nanjing Spare Composites's published scope creates a potential fit for window, door or building-envelope programs. Buyers should confirm the exact profile series, section drawing, glazing and hardware configuration, whole-assembly thermal basis, air and water performance, finish, fire claim and the certificate or report that represents the offered system.
Nanjing Spare Composites's listed grating or platform products may be relevant to industrial access systems. Qualification should identify molded or pultruded construction, resin, panel and mesh geometry, surface, support span, load and deflection limit, cut plan, clips, fire or smoke requirement and the test basis behind any published load table.
Nanjing Spare Composites's listed reinforcement products may be relevant to corrosion-sensitive concrete or civil works. Buyers should state fiber type, nominal area, guaranteed tensile property, modulus, bond surface, bend geometry, test method, design code, lot traceability and packaging. FRP reinforcement should not be specified or handled as if it were interchangeable with steel.
Nanjing Spare Composites's source record currently includes SPARE Official Chinese Website, SPARE Chinese Company Profile, SPARE Product Directory, SPARE Official English Export Website. 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 3 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 2026-08-06. 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.

According to its official website, F1 Composites is FengDu New Material's international export company. It supplies pultruded FRP profiles, gratings, fiberglass window and door systems, and custom pultrusions for overseas projects, with English-language engineering, quality documentation, export coordination and international delivery support.
Nanjing Hitech Composites Co., Ltd. publishes an integrated HICOMA and Lica offer spanning pultruded carbon- and glass-fiber profiles, high-performance reinforcement fabrics and structural adhesives. Its current official catalog explicitly lists carbon-fiber plate, rod, tube, channel, rebar and prestressed plate systems; fiberglass beams, channels, angles, tubes, plates, rebar and grating; carbon- and glass-fiber fabrics; and bonding products for wind blades, carbon plate and civil structures. The China Composites Expo directory independently supports the Nanjing exhibitor identity and its pultruded-composite and epoxy-adhesive scope. GetFRP therefore assigns only demand phrases supported by those actual products, including carbon-fiber products, plates, rods, tubes and fabrics, pultruded fiberglass profiles and fiberglass grating. An application, system or performance label is not treated as a substitute for the offered grade, section drawing, laminate architecture, adhesive TDS or project engineering.
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.
