C8 Prepainted Matt Galvanized Steel Roofing Sheets

"C8" color-coated metal sheeting is not a standard tile profile code; rather, it is an industry colloquialism for the YX130-300-600 overlapping color-coated steel tile profile (a designation stemming from early roll-forming equipment numbering or manufacturers' internal naming conventions). It belongs to the category of exposed-fastener, trapezoidal-overlap profiled steel sheets. Utilizing an aluminum-zinc alloy-coated or galvanized steel substrate, its surface is finished with organic coatings—such as Polyester (PE) or Fluorocarbon (PVDF)—thereby serving a dual function of structural load-bearing support and decorative, waterproof roofing. Model: YX130-300-600 "C8" is its common market designation. Rib Height / Wave Height: 130mm ， Determines drainage capacity and resistance to wind uplift. Rib Pitch / Wave Pitch:300mm ，Influences installation density and overlap stability. Effective Width: 600mm ， The actual net width of roof coverage provided. Thickness Range:0.3mm–0.7mm (0.4mm is most common) Thickness directly impacts structural strength and service life. Coating Type: PE (Polyester), SMP (Silicon-Modified Polyester), PVDF (Fluorocarbon) PVDF offers the highest weather resistance and is recommended for coastal or industrial environments.
