Our SGCC/SGLCC Galvalume Steel Coil is widely used in various industries, thanks to its versatile performance and durability. Here are the key application areas:

 

1. Construction Industry

Ideal for roofing, wall panels, purlins, canopies, ventilation ducts, and steel structure auxiliary materials in residential, commercial, and industrial buildings. Its excellent corrosion resistance makes it particularly suitable for coastal areas, industrial zones, and airports, where harsh environmental conditions require long-lasting materials.

 

2. Home Appliance Manufacturing

Used for air conditioner outer casings, refrigerator back panels, oven liners, and washing machine parts. The high heat resistance and corrosion resistance of Galvalume steel ensure the longevity and reliability of home appliances.

 

3. Automotive Industry

Suitable for exhaust pipe heat shields, fuel tank parts, and other components that require high temperature resistance and corrosion protection. Its good processing performance allows for complex forming to meet automotive manufacturing standards.

 

4. Other Industrial Applications

Widely used in granaries (anti-mildew), solar brackets (outdoor corrosion resistance), cable trays, and agricultural equipment. It is also an excellent substrate for pre-painted steel coils (PPGL), expanding its application scope further.

 

Below are the most common questions about our SGCC/SGLCC Galvalume Steel Coil. If you have any other questions, please feel free to contact us for a detailed answer.

 

1. What is the difference between SGCC and SGLCC Galvalume Steel Coil?

SGCC is a commercial-grade Galvalume steel coil, mainly used for general applications such as simple roofing and home appliance parts, with standard mechanical properties. SGLCC is a high-strength Galvalume steel coil, featuring higher yield and tensile strength, suitable for structural applications that require load-bearing capacity, such as steel structure purlins and automotive components.

 

2. How long is the service life of your SGCC/SGLCC Galvalume Steel Coil?

The service life depends on the coating weight and application environment. Under normal atmospheric conditions, the service life is 15-20 years with AZ60 coating weight. In coastal or industrial areas with harsh environments, choosing AZ90 or higher coating weight can extend the service life to 25-30 years.

 

3. Can you provide customized specifications for Galvalume Steel Coil?

Yes, GNEE STEEL offers fully customized solutions. We can adjust the thickness, width, coating weight, surface treatment, and steel grade according to your specific project requirements. Please provide your detailed specifications, and we will provide a tailored quote and sample.

 

4. What standards do your SGCC/SGLCC Galvalume Steel Coils comply with?

Our products strictly comply with international standards, including ASTM A792M (US standard), DIN EN10327 (European standard), JIS G3321 (Japanese standard), and GB/T 14978 (Chinese standard). We can also provide test reports and certificates to meet the import requirements of your country.

 

5. What is the lead time for your Galvalume Steel Coil?

The lead time depends on the order quantity and specifications. For standard specifications, the lead time is 7-15 working days. For customized orders, it is 15-25 working days. We will confirm the exact lead time with you after receiving your order.

 

6. Do you provide samples before bulk order?

Yes, we provide free samples (up to 2 pieces) for your quality inspection. You only need to bear the shipping cost. The sample lead time is 3-5 working days. After you confirm the sample quality, we will start production of your bulk order.
