Applications of SGLCC Galvalume Steel Coil
The versatility of SGLCC galvalume steel makes it ideal for:
Construction: Roofing sheets, wall panels, gutters, downspouts, structural profiles
Home Appliances: Refrigerators, washing machines, air conditioners, microwave ovens
Industrial: Ventilation ducts, silos, storage tanks, automotive parts, electrical enclosures
Agriculture: Greenhouse frames, livestock shelters, grain storage bins
Key Advantages of SGLCC Galvalume Steel Coil
Unmatched Corrosion Resistance: The 55% Al-Zn-Si coating combines aluminum's barrier protection and zinc's sacrificial anode effect, offering 2–6 times longer service life than conventional galvanized steel (SGCC). The normal lifespan reaches 25 years in atmospheric environments.
Excellent Heat Resistance & Reflection: Withstands continuous high temperatures up to 315°C without discoloration or coating degradation. Reflects ~70% of solar radiation, reducing building energy consumption by 15–20%.
Superior Formability & Paint Adhesion: The smooth, silver-white spangled surface (regular/zero spangle available) ensures easy stamping, bending, and welding. The coating bonds tightly with paints, enabling long-lasting color retention for pre-painted applications.
Packaging and Shipping
Adopting a professional industrial packaging solution that is moisture-proof and scratch resistant, each batch of steel is tied and fixed with customized wooden frames/steel strips, combined with anti rust coatings and cushioning pads to ensure zero damage during transportation. Clear product model, batch number, and storage identification on the outer packaging, supporting customized enterprise logos and information labels. Environmentally friendly and recyclable packaging materials practice green concepts, reducing transportation and disassembly costs.
Frequently Asked Questions (FAQ)
Q1: What is the difference between SGLCC and DC51D+AZ?
A: SGLCC (JIS G3321) and DC51D+AZ (EN 10326) are equivalent grades for commercial-quality galvalume steel coils. Both use cold-rolled substrates with 55% Al-Zn-Si coatings, offering identical corrosion resistance and formability.
Q2: What coating weight options are available for SGLCC galvalume coils?
A: Standard coating weights range from AZ30 (30 g/m²) to AZ275 (275 g/m²). Common options include AZ70, AZ100, AZ150, and AZ200. Higher coating weights provide better corrosion resistance for harsh environments.
Q3: Can SGLCC galvalume steel be used in coastal or high-humidity areas?
A: Yes. The 55% Al-Zn coating offers excellent resistance to salt spray and moisture. For coastal regions, we recommend AZ150+ coating weight with anti-fingerprint (AFP) treatment to extend service life.
Q4: What is the minimum order quantity (MOQ) for SGLCC galvalume coils?
A: The standard MOQ is 25 tons (one full coil). Smaller trial orders (10–25 tons) can be negotiated based on availability.
Q5: Is SGLCC galvalume steel suitable for pre-painted applications?
A: Absolutely. The coating's excellent paint adhesion ensures pre-painted SGLCC coils retain color and resist peeling for 15+ years. We offer pre-painted galvalume coils with RAL color options.
Q6: What is the typical lead time for SGLCC galvalume coil orders?
A: Standard production lead time is 15–20 days after deposit confirmation. Urgent orders (10–15 days) can be arranged for regular specifications.
Q7: Does GNEE STEEL provide third-party inspection reports?
A: Yes. We support SGS, BV, or other third-party inspections before shipment, providing detailed test reports for chemical composition, mechanical properties, and coating quality.
Q8: What packaging is used for SGLCC galvalume coils?
A: Standard export packaging includes waterproof paper + plastic film + metal strapping with edge protectors to prevent damage during sea/land transportation. Custom packaging is available upon request.
