About Surealong Group Corporation - Metal Products Supplier in China

China‑based Surealong Group Corporation lists six active product entries in its catalogue, all falling under metal fabrication and related welding components. The catalogue includes generic entries such as “Surealong Metal Fabrication Stamping Parts” and “Stamping Parts Welding Parts”, as well as three items that specify HS codes: sheet metal stamping parts (HS 7326.90) made from carbon steel SPCC, stainless steel 304 and aluminium 5052; aluminium stamping parts (HS 7616.99) using aluminium alloys 6061‑T6 or 5052‑H32; and a broader stamping part (HS 7326.19) covering stainless steel (SS304/SS316), carbon steel (SPCC/SGCC), aluminium (6061/5052), copper, brass and bronze. Each entry references the material families rather than a single alloy, indicating a flexible production capability across common engineering metals. The supplier is classified as an imported tier with a harbor trust tier, suggesting it operates through established Chinese export channels. The product count and material diversity point to a focus on components for downstream manufacturing such as automotive, appliance and machinery assemblies.

Product Range and Specialties of Surealong Group Corporation

Surealong’s catalogue groups its offerings into metal stamping parts and associated welding supplies. The sheet metal stamping items (HS 7326.90) typically conform to grades like SPCC (cold‑rolled carbon steel) with tensile strength around 270 MPa, while stainless‑steel variants such as SS304 meet ASTM A240 specifications and offer corrosion resistance for food‑grade or medical devices. Aluminium stamping parts (HS 7616.99) using 6061‑T6 are commonly supplied with a T6 temper that provides a minimum tensile strength of 290 MPa and are favoured for lightweight structural components. In the broader HS 7326.19 category, manufacturers often ship parts in standard 1 kg to 25 kg batches, packed in wooden crates or export‑grade pallets, and may apply surface treatments such as anodizing or phosphate coating to meet industry finish standards. Buyers usually request material certificates that reference ASTM, EN or GB standards, and may also specify dimensional tolerances in the range of ±0.1 mm for precision stamping.

Trade and Export Information - Surealong Group Corporation

China remains one of the world’s largest exporters of metal stamping components, with the majority of shipments destined for automotive assemblers in Europe, machinery manufacturers in Southeast Asia, and consumer‑electronics producers in North America. HS 7326 and HS 7616 chapters cover a broad selection of finished metal products, and customs authorities frequently request certificates of origin and compliance with RoHS or REACH when the parts contain copper or brass alloys. Typical export logistics involve 20‑ft or 40‑ft containers, each holding up to 20 metric tonnes of stamped parts, secured on wooden pallets with shrink‑wrap to protect against moisture. While Surealong does not list specific certifications, Chinese metal fabricators commonly operate under ISO 9001 quality‑management systems and may provide CE marking documentation for EU‑bound goods. Payment terms in the sector often use LC (Letter of Credit) or documentary collection, and buyers should verify the Incoterm (e.g., FOB Shanghai or CIF Los Angeles) before finalising logistics.

Sourcing from Surealong Group Corporation - Buyer Guidance

When sourcing from Surealong, buyers should request a mill test report (MTR) that details chemical composition and mechanical properties for each alloy listed in the catalogue. For stainless‑steel parts, an additional corrosion‑resistance test report (e.g., ASTM A193) may be required, while aluminium components often need a T6 temper verification and a hardness test (Brinell HB 70‑100). Sample orders are typically limited to a single piece per alloy to confirm dimensional tolerances and surface finish before bulk production. Verify that the supplier can provide material certificates aligned with GB/T, ASTM or EN standards, and confirm packaging details such as crate dimensions and moisture‑proofing if the parts will be shipped to humid climates. Finally, ensure that the HS code declared on the commercial invoice matches the product description to avoid customs delays.

What metal alloys are covered by Surealong’s sheet metal stamping parts?

The sheet metal stamping parts are listed with carbon steel SPCC, stainless steel 304 and aluminium 5052, matching common engineering grades used in automotive and appliance panels.

Which HS codes apply to Surealong’s aluminium stamping products?

Aluminium stamping parts are classified under HS 7616.99, which covers other aluminium articles not specified elsewhere in the chapter.

What certifications should a buyer request for these metal stamping components?

Buyers should ask for ISO 9001 quality‑management certification, a mill test report (MTR) referencing ASTM or GB standards, and, where applicable, CE or RoHS compliance documentation.

What are typical packaging methods for the stamped parts?

Export shipments are usually packed in wooden crates on standard pallets, wrapped with shrink‑film to protect against moisture, and loaded into 20‑ft or 40‑ft containers.

What is a common minimum order quantity (MOQ) for these parts?

MOQ levels vary by alloy but generally range from 500 kg to 2 tonnes per order, with smaller sample quantities available on request.

What lead times can a buyer expect for a standard aluminium stamping order?

Standard lead times are 30‑45 days from order confirmation, assuming material availability and no custom tooling changes.

How are welding supplies related to the stamping product line?

Surealong lists “Stamping Parts Welding Parts” as a separate catalogue entry, indicating that welding consumables compatible with the stamped components can be supplied alongside the metal parts.
