Q: What does SGCC Z12 mean?
A: SGCC Z12 is a specific grade designation for galvanized steel. SGCC refers to the base material, which is a commercial quality hot-dip galvanized steel. Z12 indicates the coating weight of the zinc applied to the steel, with Z12 representing a coating weight of 120 grams per square meter on both sides.

Q: What is the significance of a thickness of 0.351250MM for galvanized steel plate sheets?
A: The thickness of 0.351250MM refers to the gauge or thickness of the galvanized steel plate or sheet. In this case, the steel has a thickness of 0.35 millimeters. The width of 1250 millimeters indicates the width of the sheet. These dimensions determine the size and weight of the steel sheet and can impact its use in different applications.

Q: What is JISG3302?
A: JISG3302 is a Japanese Industrial Standard that specifies the requirements for hot-dip zinc-coated steel sheets and coils. It covers the mechanical properties, chemical composition, dimensions, and other specifications for galvanized steel products.

Q: What is meant by "Big Spangle" in galvanized steel?
A: "Big Spangle" refers to the appearance of the galvanized steel surface after the spangle pattern is formed during the galvanization process. Spangles are the visible crystalline patterns that form on the surface of galvanized steel due to the solidification of the zinc coating. Big Spangle indicates larger, more visible spangle patterns on the steel surface, which can provide a unique aesthetic appearance.

Q: What are the advantages of galvanized steel?
A: Galvanized steel offers several advantages, including:

• Excellent corrosion resistance, particularly in outdoor or humid environments.
• High strength and durability, making it suitable for structural applications.
• Heat resistance, allowing it to withstand high temperatures.
• Easy and cost-effective maintenance, as the zinc coating provides long-lasting protection.
• Aesthetic appeal, especially with the presence of spangle patterns.
• Recyclability, as galvanized steel can be recycled and reused.

Q: What are the common applications of SGCC Z12 Gi galvanized steel plate sheets with Big Spangle?
A: Common applications of SGCC Z12 Gi galvanized steel plate sheets with Big Spangle include construction and architecture (roofing, wall cladding, structural frameworks), automotive industry (car body panels, chassis components), electrical enclosures, and various industrial applications such as manufacturing equipment, agricultural machinery, storage tanks, and pipelines. The Big Spangle designation is often used in architectural or decorative applications for its unique visual appearance.
