Import Cold Rolled, Galvanized — Buy in Bulk from Supplier in China

Cold rolled and galvanized steel from Qingdao Baosen Steel Co., Ltd. is a dual-process material offering enhanced strength and corrosion resistance for industrial use. The cold rolling process refines grain structure and improves surface finish, while hot-dip galvanizing applies a zinc coating typically 50 to 150 micrometers thick to protect against rust in humid or saline environments. This product is supplied in coil or sheet form, with thicknesses commonly ranging from 0.3 mm to 3.0 mm and widths up to 1,500 mm, depending on the order specification.

The base material is low-carbon steel, often grade Q195, Q235, or SPCC, which provides good formability and weldability for fabrication. Zinc coating adherence is measured by triple-spot tests, with a minimum adherence of 60 g/m² per side standard for commercial-grade galvanized steel. Surface treatments may include passivation or oiling to prevent white rust during transit, and the material meets ASTM A653 or EN 10346 standards for structural applications.

This steel is used in construction for roofing, wall cladding, and structural framing, as well as in automotive body panels, appliance casings, and electrical enclosures. Importers typically source it in full coils or cut-to-length sheets, with packaging in waterproof paper and steel straps for export. Buyers confirm coil weight, inner diameter, and packaging method with the supplier to ensure compatibility with their handling equipment.

Qingdao Baosen Steel Co., Ltd. is based at No. 61 Haier Road in Qingdao, Shandong Province, China. The company operates as an imported-tier supplier with a harbor trust tier, indicating verified export capabilities. Its address and operational base in a major port city suggest strong logistics support for bulk shipments and timely dispatch.

The supplier’s profile does not specify response rate or average response time, so buyers should expect to initiate contact directly for technical or trade inquiries. No additional details on production capacity, certifications, or client history are provided in the listing, so these must be confirmed through direct communication.
