Q: What does SGCC-Z18 mean?
A: SGCC-Z18 refers to a galvanized steel coil with a zinc coating weight of 180 grams per square meter. SGCC is the designation for hot-dip galvanized steel in Japan, and the "-Z18" indicates the zinc coating weight.
Q: What is the thickness of the galvanized steel coil?
A: The thickness of the galvanized steel coil is 0.8mm, which refers to the thickness of the steel sheet before the galvanizing process.
Q: What is JISG3302?
A: JISG3302 is the Japanese Industrial Standard for hot-dip galvanized steel sheets and coils. It specifies the requirements for the mechanical properties, chemical composition, dimensions, and coating weight of galvanized steel products.
Q: What is mini spangle?
A: Mini spangle refers to the appearance of the zinc coating on the galvanized steel surface. It indicates that there are smaller and more closely spaced zinc crystals, resulting in a smoother and more uniform surface finish.
Q: What are the main properties of SGCC-Z18 0.8mm thick galvanized steel coil with mini spangle?
A: The main properties include corrosion resistance, strength, formability, and a smooth and uniform surface finish.
Q: What are the common uses of SGCC-Z18 0.8mm thick galvanized steel coil with mini spangle?
A: The galvanized steel coil with mini spangle is commonly used in various applications, including roofing, cladding, gutters, downspouts, HVAC ductwork, appliances, automotive components, and general manufacturing.
Q: Can a galvanized steel coil with mini spangle be painted or coated?
A: Yes, a galvanized steel coil with mini spangle can be painted or coated with various finishes for additional protection or aesthetic purposes. The smooth and uniform surface facilitates good adhesion of the paint or coating.
Q: Is the galvanized steel coil with mini spangle suitable for outdoor applications?
A: Yes, the galvanized steel coil with mini spangle offers excellent corrosion resistance and is suitable for outdoor applications where exposure to harsh weather conditions is expected. The zinc coating acts as a protective barrier against rust and corrosion.
Q: Can the galvanized steel coil with mini spangle be welded?
A: Yes, the galvanized steel coil with mini spangle can be welded using appropriate welding techniques and procedures. However, it is important to take precautions to prevent damage to the zinc coating during the welding process.
