Galvanized corrugated roofing sheets are a core metal cladding material in the construction industry. Manufactured from hot-rolled or cold-rolled steel substrates through hot-dip galvanizing and roll-forming processes, they boast high strength, excellent corrosion resistance, and cost-effectiveness. They are widely used in industrial plants, warehousing buildings, and prefabricated construction projects.
Classified by galvanizing process, zinc coating weight, and function, these products include various types. Among them, hot-dip galvanized products account for over 82% of the market, while PV-compatible models are the fastest-growing category. Installation must follow the six-step standard procedure: preparation, line marking, laying, fixing, sealing, and inspection. During use, load control and regular zinc coating maintenance are essential.
As a key roofing material for prefabricated buildings, it holds a 42% market share. Compared to color-coated sandwich panels and aluminum-zinc alloy corrugated sheets, this product has distinct advantages in cost and strength. In 2024, the domestic market volume reached 8.2 million tons, with exports to Southeast Asia increasing by 15% year-on-year.
In the future, the industry will develop in four major directions: green/low-carbon initiatives, high-end upgrades, intelligent integration, and market consolidation. Environmentally friendly processes and high-strength, multi-functional products will become mainstream, and the market share of leading enterprises will continue to rise.
