Corrugated sheet is a building material with a corrugated structure, manufactured through processes such as roll forming and cold bending. Common materials include aluminum, galvanized steel sheet, and rock wool composites. Its corrugated structure significantly improves the sheet’s bending and compressive strength while maintaining its lightweight properties, making it suitable for various building applications.
In the construction industry, corrugated sheets are mainly used for roofing and walls of large-span steel structure factories, airport terminals, and other buildings, providing waterproofing, fireproofing, and corrosion protection, while enhancing structural rigidity. For example, aluminum corrugated sheets are lightweight, high-strength, and have good weather resistance, making them suitable for roofing, walls, and interior and exterior decoration in industrial and civil buildings; galvanized corrugated sheets are commonly used for roof coverings, drainage system accessories, and the enclosure structures of industrial storage facilities. Rock wool corrugated sheets, due to the excellent thermal insulation, sound insulation, and fire resistance (fire resistance rating A) of their core rock wool, are often used for industrial equipment insulation, cleanrooms, or roofing and partitions in buildings with high safety requirements.
In industrial applications, corrugated sheets are widely used for insulation layers in power plant chimneys, anti-corrosion wall panels in chemical plants, logistics facilities (such as lockers and shelves), and agricultural greenhouses, offering advantages such as wear resistance, ease of installation, and thermal insulation. Composite corrugated sheets combine corrugated steel sheets with insulation materials, possessing energy-saving, fire-resistant, and corrosion-resistant properties, making them suitable for various industrial plants and warehousing facilities.
Furthermore, corrugated sheets are used in rail transit and public buildings (such as stadiums and hospitals) for roofing, curtain walls, or ceilings. Their modular design facilitates rapid construction, and some types are recyclable, meeting the needs of sustainable development.
