Description

Corrugated steel plate, also known as Corrugated Roofing Steel Sheet, roofing steel sheet, or arched corrugated steel roof, is a thin-walled steel sheet formed by mechanical roll forming with a continuous corrugated cross-section. Corrugated Metal Roofing Sheet is commonly used for roofing industrial plants, warehouses, stadiums, and other buildings, serving both structural load-bearing and enclosure functions.

Classification of Corrugated Steel Plate:

1. By Structural Form: Corrugated steel plates are divided into arched corrugated steel roofs (beamless arches/space tiles, spans 6–40m, integrated load-bearing and enclosure) and ordinary profiled (corrugated) steel sheets (mostly used for lightweight roofs or walls, without an integrated arched structure).

2. By Cross-Section Waveform: Common corrugated steel plates include U-shaped, V-shaped (such as the MIC series), trapezoidal, and corrugated (such as the 760/820/900 types). Arched roofs often use U/V-shaped channel plates, while ordinary roofs often use trapezoidal or corrugated profiled sheets.

3. By Material and Coating: Corrugated Steel Plates include hot-dip galvanized steel sheet (GI), aluminized zinc steel (GL/Galvalume), and color-coated steel sheet (PPGI/PPGL). The substrate thickness is typically 0.4–1.5 mm (≥0.6 mm for load-bearing buildings), and the coating weight is 60–275 g/m².

4. By Application: Corrugated Steel Plates are categorized into building roofs (e.g., arched or high-wave panels for factories, grain depots, and stadiums), industrial enclosures (low-wave height, economical profiled sheets), and special applications (e.g., agricultural greenhouses, temporary structures, metal curtain walls).

Applications of Corrugated Steel Plates:

1. Industrial and Warehousing Buildings: Such as factories, warehouses, grain depots, material yards, and hangars, due to their beam-free and purlin-free construction, spans of 6–40 meters, open spaces, and good load-bearing and wind/snow resistance.

2. Public and Commercial Facilities: Corrugated Steel Plates are suitable for stadiums, exhibition halls, farmers’ markets, schools, hospitals, etc., offering both rapid construction and aesthetic appeal.

3. Agriculture and Temporary Facilities: Used for livestock sheds, greenhouses, cold storage facilities, and post-disaster/temporary buildings; weather-resistant, corrosion-resistant, and easy to install.
