Shandong Dingcheng Liye Top 5 Steel Lines: Hot Rolled, Cold Rolled, Galvanized, PPGI and Stainless

One Steel Export Partner, Five Core Product Families

As a specialized manufacturer and exporter of flat steel products, Shandong Dingcheng Liye Materials Co., Ltd (official export platform: metalsteelsheets.com) has built its reputation around five core product lines that global B2B buyers order most: hot rolled steel, cold rolled steel, galvanized/galvalume steel, PPGI/PPGL steel and stainless steel. Headquartered in Shandong, China and exporting 50%-60% of its output, the company serves distributors, importers, contractors and OEM factories across Southeast Asia, the Middle East, Africa, South America and Europe.

1. Hot Rolled Steel

The backbone of every construction and fabrication project. Dingcheng supplies hot rolled coils and plates in widely specified grades, with stock available for fast loading.

• Grades: ASTM A36, Q235B, SS400, SS490/SS540, SPHC/SPHD/SPHE, S275/S355
• Thickness: 0.8-12mm and above; Width: 1000-2200mm; length cut to request
• Standards: ASTM, JIS G3101, EN10025, GB
• Typical use: steel structures, bridges, ships, tanks, heavy machinery and further cold rolling

2. Cold Rolled Steel

Where surface quality and dimensional precision matter, cold rolled steel (CRC) delivers. Ideal for buyers who need a clean base material for stamping, enameling or painting.

• Grades: SAE1006/1008/1010, SPCC/SPCD, DC01-DC04
• Features: tighter thickness tolerance (±1%), improved surface finish, good formability
• Typical use: home appliances, automotive parts, furniture, lockers, lighting and steel doors

3. Galvanized & Galvalume Steel (GI/GL)

Corrosion protection starts here. From flat galvanized sheets (e.g., DX51D+Z Z150 4x8 sheets) to corrugated GI/GL roofing sheets, this line protects structures against humidity and coastal environments.

• Coating: hot-dipped zinc (GI) and zinc-aluminum (GL, e.g., AZ150) with regular, minimized or zero spangle
• Forms: flat sheets, coils, corrugated roofing sheets in multiple profiles
• Typical use: roofing, wall cladding, purlins, ductwork, silos and agricultural buildings

4. PPGI / PPGL Steel

Pre-painted steel adds color, durability and branding to metal buildings. Dingcheng offers prepainted galvanized/galvalume coils and roofing sheets in a wide RAL color range with consistent film thickness.

• Base: hot-dip galvanized or galvalume, top-coated with polyester, SMP or PVDF systems
• Forms: PPGI/PPGL coils and cut-to-size roofing sheets
• Typical use: color steel roofing, sandwich panels, ceiling tiles, home appliances and metal furniture

5. Stainless Steel

For hygiene-critical and high-corrosion applications, the stainless line covers the classic 200/300 series with a range of finishes suitable for further fabrication.

• Grades: 201, 304/304L, 316/316L sheets, plates and coils
• Finishes: 2B, BA, No.4, HL and mirror options
• Typical use: food processing, chemical equipment, marine hardware, elevators and architectural decoration
