About Union Metal Intermational Co., Ltd. - Stainless Steel Sheets Supplier in China

Union Metal Intermational Co., Ltd. is based in China and lists six active stainless‑steel sheet products. The catalogue includes 304 stainless steel with an 8 k mirror finish, 201 stainless steel offered as super‑mirror panels, AISI 316L mirror sheet, titanium‑coated 304 sheet, standard etched 304 plate, and a 201 hairline‑etched sheet. Each entry specifies the grade and surface treatment but provides no further dimensional data. The products fall under the stainless‑steel sheet segment, which is commonly classified under HS Chapter 73, heading 7208 for flat‑rolled products.

The supplier’s list reflects common industrial finishes such as mirror, super‑mirror, hairline, and etched, which are used in architectural cladding, food‑processing equipment, and decorative applications. Grades 304, 201 and 316L are the most frequently exported stainless‑steel grades from China, meeting ASTM A240 and EN 10088 specifications for chemical composition and mechanical properties. Surface roughness for mirror finishes typically targets Ra ≤ 0.2 µm, while hairline and etched finishes are described by visual texture rather than numeric roughness. No HS codes are provided in the source data, so only the general HS 7208 family is referenced.

Product Range and Specialties of Union Metal Intermational Co., Ltd.

The catalogue covers six distinct stainless‑steel sheet variants: 304 8 k mirror finish, 201 super‑mirror panels, AISI 316L mirror sheet, titanium‑coated 304 sheet, standard etched 304 plate, and 201 hairline‑etched sheet. All items are flat‑rolled sheets intended for secondary processing or direct installation. In the broader market, stainless‑steel sheets are supplied in thicknesses from 0.2 mm to 6 mm, with width up to 2000 mm and length up to 12 m, and are often ordered in bundles on wooden pallets or shrink‑wrapped for export.

Industry practice classifies these grades by corrosion resistance and formability: 304 offers general‑purpose corrosion resistance, 201 provides a lower‑cost alternative with higher manganese content, and 316L adds molybdenum for improved chloride resistance. Mirror finishes are produced by successive polishing stages to achieve a reflective surface, while etched or hairline finishes are created by chemical or mechanical treatment to produce a decorative texture. Buyers typically request mill test certificates that confirm compliance with ASTM A240, chemical composition limits (e.g., C ≤ 0.08 % for 304), and tensile strength values (e.g., 515 MPa for 304).

Trade and Export Information - Union Metal Intermational Co., Ltd.

Stainless‑steel sheets from China are regularly shipped to construction, automotive, appliance, and food‑equipment manufacturers in Europe, North America, and Southeast Asia. The relevant HS classification is 7208, which covers flat‑rolled stainless‑steel plates, sheets and strip, of width ≥ 600 mm. Export logistics commonly use 40‑ft containers with sheets packed on pallets, protected by cardboard separators and moisture‑resistant film. Incoterms such as FOB Shanghai or CIF European ports are typical, with buyers often requiring compliance with ISO 9001 quality‑management systems and CE marking for end‑use in the EU.

Regulatory considerations include the EU REACH registration for alloying elements, and US ASTM standards for structural applications. Importers frequently ask for third‑party inspection reports (e.g., SGS, Bureau Veritas) confirming surface finish, thickness tolerance (±0.1 mm typical), and mechanical properties. Because the catalogue does not list specific certifications, buyers should verify that the supplier can provide the necessary test documentation before shipment.

Sourcing from Union Metal Intermational Co., Ltd. - Buyer Guidance

When sourcing stainless‑steel sheets from Union Metal Intermational, request a mill test certificate (MTC) that details chemical composition, mechanical properties, and heat‑treatment condition for each grade. Verify surface‑finish specifications by asking for a surface‑roughness report (Ra or Rz values) and, for mirror finishes, a visual inspection sample or high‑resolution photograph. Buyers should also obtain a packaging and handling statement that confirms the sheets are palletized, shrink‑wrapped, and protected against moisture during transit.

Typical minimum order quantities for flat‑rolled sheets range from 1 ton to 5 tons depending on thickness and grade, with lead times of 15‑30 days after order confirmation. Request a pre‑shipment inspection report that includes dimensional checks (thickness, width, length) and a random sample test for corrosion resistance (e.g., salt‑spray test). Ensure that any required certifications such as ISO 9001, CE marking, or REACH registration are supplied as part of the documentation package before finalizing the purchase.

What stainless‑steel grades are listed by Union Metal Intermational?

The supplier lists grades 304, 201 and AISI 316L, each offered with specific surface treatments such as mirror, super‑mirror, titanium‑coated, etched or hairline finish.

Are mill test certificates available for these products?

The facts do not specify documentation, so buyers should request an MTC for each grade to confirm chemical composition and mechanical properties in line with ASTM A240.

Which HS code applies to the stainless‑steel sheets?

Stainless‑steel flat‑rolled sheets are generally classified under HS Chapter 73, heading 7208, which covers plates, sheets and strip of stainless steel.

What surface‑finish specifications are typical for mirror‑finish sheets?

Mirror finishes usually target a surface roughness of Ra ≤ 0.2 µm and are produced by multiple polishing stages to achieve high reflectivity.

What packaging format is used for export?

Export shipments are commonly palletized, with sheets separated by cardboard and wrapped in moisture‑resistant film, then loaded into 40‑ft containers.

Which Incoterms are most often used for Chinese stainless‑steel sheet exports?

Buyers typically see FOB Shanghai or CIF ports in Europe and North America, allowing the buyer to arrange freight and insurance as needed.

What certifications should a buyer request for these sheets?

Buyers should request ISO 9001 quality‑management certification, CE marking for EU markets, and any REACH registration documentation for alloying elements.

What are typical lead times and MOQ for these products?

Lead times are usually 15‑30 days after order confirmation, with minimum order quantities ranging from 1 ton to 5 tons depending on grade and thickness.
