Precoated VCM Metal Sheets for Wall Panels

The waterproofing performance of coated metal panels varies depending on the product type, but generally, they all exhibit good water resistance, moisture resistance, corrosion resistance, and aging resistance. When selecting coated metal panels, factors such as physical properties, ease of installation, environmental friendliness, and cost should be considered based on the specific application scenario and requirements to ensure optimal waterproofing performance. Coated metal panels (such as PVDF fluorocarbon coated and PVC coated panels) are essentially decorative and protective composite panels, widely used in curtain walls, interior decoration, and other applications. Their "waterproofing" ability is reflected only in the moisture-proof and rust-proof barrier effect of the coating layer on the substrate, and does not replace the structural waterproofing layer in underground engineering or roofing. Durability testing of coated metal panels focuses on simulating environmental aging and mechanical damage, rather than resistance to water pressure; the core objective is to ensure the long-term integrity of the coating layer, thereby indirectly achieving "moisture and corrosion resistance."
