Galvanized steel sheet DX51D

1. Product Overview
SGCC galvanized steel sheet is a hot-dip galvanized commercial quality product engineered for superior corrosion resistance in general manufacturing and construction applications. Its primary use lies in forming, bending, and light fabrication across HVAC, roofing, and electrical enclosures. The key value proposition is an optimal balance between cost efficiency and durable zinc-layer protection, reducing long-term maintenance. Strategically, it is a market benchmark for standardized, high-volume industrial supply chains requiring consistent mechanical formability.

2. Key Specifications & Technical Characteristics

• Material Standard: JIS G3302 SGCC (commercial grade)

• Zinc Coating Mass: typically Z08–Z27 (80–275 g/m², double-side)

• Base Metal Thickness: 0.20 mm – 2.30 mm

• Width Range: 600 mm – 1,250 mm (slit coils or sheets)

• Surface Finish: regular spangle, minimized spangle, or zero spangle

• Surface Treatment: chemical passivated (chromate or Cr³⁺), oiled / unoiled / anti-fingerprint

• Physical Form: flat sheet or coil, clean edges

• Packaging: moisture-proof paper + galvanized steel strapping + palletized seaworthy export bundle

• Shelf Life: 12 months in dry, non-condensing storage (optimized)

3. Core Industrial Applications

• HVAC industry: air conditioner casings, ventilation ducts – SGCC enables consistent deep drawing without flaking.

• Construction & roofing: corrugated roofing sheets, wall panels – outperforms bare steel in humid/salt-laden environments at lower cost than stainless.

• Electrical enclosures: switchgear cabinets, junction boxes – offers reliable grounding and paint adhesion.

• Automotive parts (non-exterior): brackets, inner body panels – superior formability vs. full-hard galvanized alternatives, reducing die wear by ~15–20%.

4. Competitive Advantages

• Quality consistency: 100% zinc coating weight verification per coil; zero spangle control ensures uniform surface for painting.

• Supply reliability: dual-source mill contracts with <10 days average lead time for standard dimensions.

• Logistics capability: direct container or break-bulk loading from three regional ports (Asia, Middle East, Europe).

• Price competitiveness: hedge-ready pricing with volume-based quarterly rebates; lower total landed cost vs. CGCC or prepainted options for bare-end uses.

• Sustainability: 100% recyclable substrate; optional Cr³⁺ passivation compliant with EU REACH and RoHS.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): BULK 20MT per size/coating configuration

• Loading capacity: ~25 MT per 20’ dry container (coils up to 1,250mm width); ~22 MT for slit sheets on pallets
