Product Introduce<\/h2><\/div>\n\n\n\n

SGCC is the designation of hot-dip galvanized<\/a><\/span> steel plates in the Japanese Industrial Standard JIS<\/span> <\/a>G3302. Simply put, SGCC stands for “cold-rolled<\/span><\/a> commercial grade hot-dip galvanized steel<\/a>“. It is a universal galvanized steel<\/a> plate made from ordinary carbon structural steel as the substrate, through cold rolling and hot-dip galvanizing processes. The surface is covered with a uniform zinc layer, providing excellent corrosion resistance.<\/p>\n\n\n\n

Applications of SGCC Galvanized Steel<\/h2><\/div>\n\n\n\n

With excellent corrosion resistance, formability, and cost-effectiveness, SGCC is widely used in multiple industries. JIS G3302 defines it as a “commercial grade (CQ)” material suitable for forming processing.<\/p>\n\n\n\n

Architecture and Infrastructure:<\/strong><\/p>\n\n\n\n

Roof panel, corrugated board
Steel doors, floor slabs, structural purlins
Cable trays, ventilation ducts, guardrails
External wall cladding, building curtain wall<\/p>\n\n\n\n

Home appliances and electronics:<\/strong><\/p>\n\n\n\n

Computer case, office furniture frame
Refrigerator back and side panels
Air conditioning casing (indoor\/outdoor unit)
Washing machine casing, microwave oven, water heater
TV backboard, dehumidifier<\/p>\n\n\n\n

Automobiles and Transportation:<\/strong><\/p>\n\n\n\n

Non load bearing structural components, such as chassis guards, fenders, and side anti scratch strips
Bus interior and exterior panels, truck cab panels, trunk lid<\/p>\n\n\n\n

Agriculture and Industry:<\/strong><\/p>\n\n\n\n

Agricultural equipment casing and storage bin
Electrical control cabinet, distribution box
General sheet metal processing and stamping parts<\/p>\n\n\n\n

Advantages of SGCC galvanized steel<\/h2><\/div>\n\n\n\n

Excellent anti-corrosion protection<\/strong> – the zinc layer acts as a sacrificial barrier. Even if the surface is scratched, the surrounding zinc will still protect the exposed steel substrate through electrochemical action. The service life can reach 30-50 years in general environments.<\/p>\n\n\n\n

Good formability<\/strong> – SGCC can be cut, bent, stamped, and welded using standard methods. After appropriate surface treatment, it is also compatible with powder coating and paint.<\/p>\n\n\n\n

High cost-effectiveness<\/strong> – Compared to stainless steel or aluminum, SGCC has much lower material costs and provides sufficient corrosion resistance for most applications. In terms of price, the basic grade is about 450-600 US dollars per ton, and the high coating is about 750-870 US dollars per ton.<\/p>\n\n\n\n

Widely available<\/strong> – SGCC is a standard grade for steel suppliers worldwide, with most thicknesses and widths available in stock.<\/p>\n\n\n\n

Environmentally friendly<\/strong> – both steel and zinc can be 100% recycled, and the hot-dip galvanizing process does not use harmful solvents or volatile organic compounds.<\/p>\n\n\n\n
