The product list includes carbon fiber roll‑wrapped tubes, telescopic poles, 3K rectangular tubes, antenna masts, water‑fed poles, and various custom carbon composite parts. Fiberglass offerings comprise colorful pipes, hot‑sale tubes, and related accessories such as water‑fed pole brushes and adaptors. Each entry is classified under the supplier’s top categories of Carbon and Fiberglass Products. The catalogue does not provide HS codes, but the items fall within standard composite material classifications used in international trade.

Product Range and Specialties of Weihai Xinbo Composite Products Co., Ltd.

The catalogue comprises 13 items split between carbon‑fiber and fiberglass solutions. Carbon products include roll‑wrapped tubes, telescopic poles, 3K rectangular tubes, antenna masts, water‑fed poles, and roll‑wrapped carbon sheets, as well as custom composite components. Fiberglass items consist of colorful pipes, standard tubes, and accessories such as brushes and adaptors for water‑fed poles.

In the carbon‑fiber market, 3K fabrics are widely used for moderate strength applications, typically offering tensile strengths of 3.5‑4.0 GPa and modulus around 230 GPa. Roll‑wrapped tubes are often manufactured to wall thicknesses of 0.5‑2 mm and diameters from 20 mm up to 200 mm, compatible with aerospace, automotive, and wind‑energy structures. Fiberglass GRP tubes generally meet ASTM D2583 specifications, with tensile strength 200‑350 MPa and density near 1.9 g/cm³, suitable for conduit, signage, and outdoor installations.

Trade and Export Information - Weihai Xinbo Composite Products Co., Ltd.

China is a major exporter of carbon‑fiber and glass‑reinforced polymer components, shipping primarily to North America, Europe, and Southeast Asian markets where aerospace, automotive, and renewable‑energy sectors drive demand. The products listed fall under HS chapter 68 for composite articles, which are subject to standard customs valuation and may require import permits where aerospace applications are concerned.

Buyers typically request ISO 9001 quality‑management certification, ISO 14001 environmental compliance, and where applicable CE marking for EU market entry. Composite parts are usually packed in wooden crates or reinforced cardboard with moisture‑barrier liners to protect the fibers during sea freight, and shipments are commonly arranged on 20‑ft or 40‑ft containers under FOB or CIF terms. Chinese exporters often provide material test reports, including tensile strength and fiber volume fraction, to satisfy buyer due‑diligence.

Sourcing from Weihai Xinbo Composite Products Co., Ltd. - Buyer Guidance

When sourcing carbon‑fiber tubes or 3K woven sheets from this supplier, request a mill test report that confirms tensile strength, modulus, fiber content, and resin system. Verify that the roll‑wrapped tubes meet the specified wall‑thickness and diameter tolerances before confirming order quantities. For fiberglass pipes, ask for compliance with ASTM D2583 or equivalent standards and for a visual inspection of surface finish.

Because the catalogue does not list certifications, buyers should obtain copies of ISO 9001 or other quality‑system certificates directly from the supplier. Samples of typical lengths are usually provided on a paid basis, allowing verification of fiber lay‑up and finish before full‑scale production. Confirm packaging details and container loading plans to ensure the composite items are protected during transit.

What types of carbon‑fiber products does Weihai Xinbo offer?

The supplier lists carbon‑fiber roll‑wrapped tubes, telescopic poles, 3K rectangular tubes, antenna masts, water‑fed poles, and 3K woven sheets, as well as custom composite parts.

Are custom carbon‑composite parts available?

Yes, the catalogue includes a line for custom carbon composites, indicating the ability to produce tailored shapes or lay‑up configurations on request.

What standard specifications apply to the 3K carbon‑fiber sheets?

3K carbon‑fiber fabrics are commonly specified with a tensile strength of 3.5‑4.0 GPa, modulus around 230 GPa, and a fiber areal weight of roughly 300‑400 g/m². Buyers should verify these values on the mill test report.

Which certifications should a buyer request for these composites?

Buyers should ask for ISO 9001 quality‑management certification, ISO 14001 environmental compliance, and any CE or aerospace‑specific approvals required for the target market.

What packaging is used for shipping carbon‑fiber tubes?

Exporters typically pack carbon‑fiber tubes in reinforced cardboard or wooden crates with moisture‑barrier liners, securing the items with foam or straps to prevent fiber damage during sea freight.

What is the typical lead time for a fiberglass pipe order?

Lead times for standard fiberglass tubes usually range from 4 to 8 weeks after order confirmation, depending on quantity and any required surface finishing.

How can a buyer obtain a material test report?

Request a mill test report from the supplier before finalizing the order; the report should detail tensile strength, modulus, fiber volume fraction, and resin type for the specific batch.

What are the minimum order quantities for roll‑wrapped carbon tubes?

The supplier does not publish MOQs in the catalogue, so buyers need to inquire directly for the minimum length or weight requirements for roll‑wrapped tubes.
