About Davin International Co., Ltd. - Aluminum Composite Panel Supplier in China

Davin International Co., Ltd. is based in China and currently lists five active products in its catalogue. The company focuses on aluminum‑based building components, specifically aluminium extrusion profile, aluminum frame, solar frame, aluminum angle, and aluminum extrusion. The aluminium extrusion entry is recorded under HS code 7604.29 and is manufactured from aluminum alloy 6063 or 6061. These items fall within the broader aluminum composite panel market segment identified as the supplier’s top category. The catalogue does not provide HS codes for the other four items.

The listed aluminium extrusion profile and angle are standard extruded sections used for framing and structural applications. The aluminum frame and solar frame are typically supplied for façade systems and photovoltaic mounting, respectively. All products are described using generic material terms without specific dimensions, surface finishes, or certifications in the source data. The supplier’s imported tier and harbor trust tier indicate that it sources products for resale rather than manufacturing.

Product Range and Specialties of Davin International Co., Ltd.

The catalogue includes aluminium extrusion profile, aluminum angle, aluminum frame, solar frame and a generic aluminium extrusion. In the industry, extrusion profiles and angles are produced from alloys 6061‑T6 or 6063‑T5, with tolerances of ±0.2 mm on dimensions and surface roughness Ra ≤ 0.8 µm. Frames for building façades and solar mounting are often supplied in standard lengths of 2 m, 3 m or cut‑to‑size, with optional anodizing or powder‑coat finishes to meet corrosion requirements. The generic aluminium extrusion listed under HS code 7604.29 conforms to ASTM B221 and EN 755‑2 specifications, which define mechanical properties such as tensile strength ≈ 310 MPa for 6061‑T6 and 240 MPa for 6063‑T5.

Typical export quantities are packed in wooden crates or on pallets, with a 20‑ft container holding roughly 12 tonnes of extruded aluminium and a 40‑ft container up to 24 tonnes. Buyers often request detailed drawings, alloy certification sheets and surface‑treatment reports to verify compliance with project specifications.

Trade and Export Information - Davin International Co., Ltd.

China is one of the world’s largest exporters of aluminium extrusions and related building components. Buyers from the European Union, United States, Middle East and Southeast Asia regularly import HS chapter 76 products for construction, façade systems and solar‑energy projects. Commonly required certifications include ISO 9001 quality‑management, ASTM B221 test reports for alloy composition, and CE marking for products used in EU construction. Export shipments are usually arranged under FOB Shanghai or Ningbo, with CIF options to major ports such as Rotterdam, Los Angeles, Dubai and Singapore. Packaging standards call for moisture‑resistant wooden crates, internal bracing and shrink‑wrap to protect profiles during sea transit.

Sourcing from Davin International Co., Ltd. - Buyer Guidance

When sourcing aluminium extrusions from Davin International, request the material test report confirming the alloy (6061 or 6063) and temper designation (T6, T5, etc.). Ask for dimensional tolerance certificates, surface‑finish specifications and, where applicable, CE conformity or ISO 9001 audit copies. Verify that the supplier can provide samples of the extrusion profile, angle or frame before confirming bulk orders, and confirm packaging details (crate size, pallet configuration) to ensure safe container loading. Typical minimum order quantities range from 5 tonnes for standard profiles to 15 tonnes for custom‑cut solar frames, with lead times of 30‑45 days from order confirmation.

What aluminium alloys are offered in the listed extrusion products?

The catalogue specifies aluminium alloy 6063 or 6061 for the extrusion product, which are the standard alloys used for architectural and structural extrusions.

Which HS code applies to the aluminium extrusion item?

The aluminium extrusion is classified under HS code 7604.29, covering aluminium extrusion products of other shapes.

What certifications should I request before purchasing?

Buyers typically ask for an ISO 9001 quality‑management certificate, an ASTM B221 material test report for alloy verification, and CE marking documentation if the goods are intended for the EU market.

How are the aluminium frames and solar frames usually shipped?

Frames are commonly packed in wooden crates or on pallets, shrink‑wrapped for moisture protection, and shipped in 20‑ft or 40‑ft containers under FOB or CIF terms.

What are the typical dimensions and tolerances for aluminium angles?

Industry standards for aluminium angles specify tolerance of ±0.2 mm on width and thickness, with standard section sizes ranging from 20 mm × 20 mm to 100 mm × 100 mm, depending on the project.

Can I obtain samples of the extrusion profile before a large order?

Suppliers usually provide a short sample of the extrusion profile, including a cut‑to‑size piece and accompanying material test report, to allow verification of dimensions and alloy before confirming bulk quantities.

What are the common lead times for custom solar frames?

Custom solar frames generally require 30‑45 days from order confirmation, depending on the complexity of the design and any special surface‑treatment requests.

Which markets most frequently import these aluminium building components?

The main import markets are the European Union, United States, Middle East and Southeast Asian countries, where aluminium extrusions are used for façade systems, solar‑panel mounting and general construction applications.
