Product Description
Corrugated Roof Sheet is a variety of wave-shaped pressed panels made of colour-coated galvanized steel sheets by rolling and cold bending. Corrugated sheet has the characteristics of light weight, high strength, rich colour, convenient and quick construction, earthquake, fire and rain resistance, long service life and maintenance-free, and is suitable for building walls and external decoration of large-span steel roofs for warehouses of industrial and civil buildings.

| Surface | Description |
| Zero Spangle | Add zinc flower promotion elements to the zinc liquid. When the zinc layer solidifies, no zinc flowers are formed. The grains are very fine and smooth |
| Small Spangle | Control the solidification process of the zinc layer to obtain zinc flowers that are relatively uniform and small in size but still visible to the naked eye |
| Regular Spangle | Zinc flowers of various sizes formed during the natural solidification process without controlling the zinc layer |
| Large Spangle | The substrate roughness is too low, there are few nucleation points, and the ratio between the nucleation rate and the grain growth rate during the crystallization process is small, resulting in the formation of larger zinc grains |
