The catalogue specifies materials such as an aluminum‑zinc alloy (55 % Al, 43.4 % Zn, 1.6 % Si), cold‑rolled carbon steel and zinc‑coated color steel. The supplier is classified as an imported, harbor‑tier supplier on the platform.

Product Range and Specialties of Se-Chang Steel Co., Ltd

The listed catalogue comprises hot‑dipped aluminized steel (AL) typically supplied in coil widths from 800 mm to 1250 mm and thicknesses between 0.5 mm and 2.0 mm, conforming to ASTM A792 for aluminum‑coated steel. Stainless steel sheets are generally offered in grades such as 304 and 316, meeting ASTM A240 specifications for corrosion resistance. The Alu‑Zinc alloy coated steel (GA) under HS 7210.61 is a dual‑metal coating used for enhanced formability and corrosion protection, often produced to ISO 1461 surface‑preparation standards with coating weights around 70‑120 g/m². Cold rolled steel coil (CR) under HS 7209.17 is a carbon‑steel product commonly supplied to ASTM A1011 tolerances, with typical thicknesses from 0.5 mm to 3.0 mm and surface roughness Ra ≤ 0.8 µm. Green & white board (color steel) under HS 7210.70 uses a zinc‑based base with polymeric colour layers, frequently meeting EN 10346 for coated steel sheets and supplied in standard coil lengths of 6 m to 12 m.

Trade and Export Information - Se-Chang Steel Co., Ltd

South Korea is a major exporter of flat‑rolled steel products, supplying automotive manufacturers, construction firms and appliance assemblers across East Asia, the Middle East and Europe. HS chapter 72 items such as 7209 and 7210 are subject to customs duties that vary by destination, and many importers require a Certificate of Origin and a Mill Test Certificate for compliance verification. Typical certifications sought for these steel grades include ISO 9001 quality management, ISO 14001 environmental management and product‑specific standards such as ASTM, EN or JIS. Export shipments are usually packed in standard 20‑ft or 40‑ft containers on wooden pallets, with shrink‑wrap protection; FOB or CIF terms are common. South Korean steel exporters often work with inspection agencies like SGS or Bureau Veritas to provide pre‑shipment inspections under the buyer’s chosen Incoterm.

Sourcing from Se-Chang Steel Co., Ltd - Buyer Guidance

When sourcing from Se‑Chang Steel, buyers should request the Mill Test Certificate for each steel grade, a chemical composition analysis and, where applicable, coating thickness reports that reference ASTM A792 or ISO 1461. Verify that the supplier can provide compliance documents for the specific standards required by the end‑use, such as ASTM A240 for stainless sheets or EN 10346 for colour‑coated steel. Confirm packaging details - coil length, pallet dimensions and whether shrink‑wrap or protective film is applied - and clarify the minimum order quantity, which for flat‑rolled steel typically starts at 5 metric tonnes. Lead times for cold‑rolled and coated coils from South Korea usually range from 30 to 45 days, depending on production scheduling and shipping terms.

What steel grades are available in the stainless steel sheets listed by Se‑Chang Steel?

The catalogue mentions stainless steel sheets without a specific grade, so buyers should ask for the exact ASTM or JIS grade, such as 304 or 316, and request the corresponding Mill Test Certificate.

Does Se‑Chang Steel provide coating weight data for the Alu‑Zinc alloy coated steel (GA)?

The product is identified with HS code 7210.61 and an aluminum‑zinc alloy composition; buyers should request a coating weight specification, typically expressed in grams per square metre, and a surface‑preparation report conforming to ISO 1461.

What documentation is needed to clear customs for the cold rolled steel coil (CR) under HS 7209.17?

Customs usually require a commercial invoice, a Certificate of Origin, and a Mill Test Certificate showing compliance with ASTM A1011. An inspection certificate from a recognized agency can further facilitate clearance.

Are there standard packaging practices for the green & white board steel (color steel) under HS 7210.70?

Color‑coated steel is commonly shipped on wooden pallets wrapped in shrink‑film, with coil lengths of 6 m to 12 m. Buyers should confirm pallet size, film thickness and whether edge protection is included.

What are typical minimum order quantities for Se‑Chang Steel’s flat‑rolled products?

For coil products from South Korean manufacturers, minimum orders often start at 5 metric tonnes per grade, though exact MOQ should be confirmed for each product line.

Which certifications should a buyer verify before purchasing stainless steel sheets from this supplier?

Buyers should request ISO 9001 for quality management, the Mill Test Certificate for the stainless grade, and any relevant ASTM or EN standards such as ASTM A240 or EN 10088 that match the intended application.

How long does it take to ship the Alu‑Zinc alloy coated steel from South Korea to Europe?

Lead times typically range from 30 to 45 days, covering production scheduling, inland transport to the port and sea freight under FOB or CIF terms, depending on the chosen Incoterm.

Can Se‑Chang Steel provide pre‑shipment inspection reports for the hot dipped aluminized steel (AL)?

While the catalogue does not list a specific inspection report, buyers can request a pre‑shipment inspection from agencies such as SGS or Bureau Veritas to verify coating thickness and dimensional tolerances.
