FAQ
What is the typical lifespan of a color steel wall panel roof system?
A properly installed color steel wall panel or roof system from ChinaCNU Steel can have a service life of 20-30 years. The longevity depends on the quality of the PPGI coating, the local environment (e.g., coastal or industrial areas), and regular maintenance. Our panels use high-quality galvanized base steel and durable paint systems for enhanced corrosion resistance.
Can you customize the dimensions and color of the PPGI insulated panel?
Yes, customization is a core service. We can tailor the panel width, total thickness, core density, and the color of the PPGI insulated panel to match your architectural plans or brand colors. Please provide your specific requirements during inquiry for a precise quote.
What are the advantages of using an EPS core in a sandwich panel for cold storage?
Using an EPS sandwich panel for cold storage offers excellent thermal insulation with a low K-value, effectively maintaining temperature and reducing energy costs. EPS is also moisture-resistant, lightweight for easier installation, and cost-effective compared to some other core materials, making it a popular choice for temperature-controlled environments.
What is the packing method for export to ensure the panels arrive undamaged?
We use robust, weather-proof export packing. Panels are stacked on wooden pallets or in a sturdy steel frame, securely strapped, and wrapped in multiple layers of waterproof plastic film. This method, proven through our exports to over 50 countries, protects the panels and the color steel wall panel surface from moisture, scratches, and transit damage.
