flashing

Colored stone metal tile accessories - flashing board is composed of aluminum zinc coated steel plate as the substrate, colored sand particles, and acrylic resin. Popular explanation: Flashing refers to the waterproofing method of roof parapets, eaves, or high and low roof walls. Its main function is to ensure that the parapets, eaves, and high and low roof walls are not washed away by rainwater, and to protect the waterproof layer of other parts of the roof (from water ingress). The contact between the flashing board and rainwater requires high anti-corrosion requirements, and generally requires aluminum zinc plating treatment.
