Frequently Asked Questions (FAQ)
1. What does the 10-year color warranty cover?
Our warranty covers excessive fading (ΔE > 5), chalking (ASTM D4214 rating
2. What is a Mill Test Report (MTR) and why is it important?
An MTR is a quality document that lists the mechanical properties, chemical composition, and coating analysis of the steel coil used in your panels. It ensures traceability and verifies that the material meets agreed specifications. We provide an MTR for every batch, giving you full transparency.
3. Can I get a sample panel before placing a bulk order?
Yes, we offer sample panels (typically 300mm x 300mm) with your selected color and coating. Samples are free but shipping charges may apply. Contact our sales team to arrange.
4. What is the minimum order quantity (MOQ)?
Our standard MOQ is 2 tons per color and gauge. For smaller trial orders or custom projects, please inquire; we can sometimes accommodate based on availability.
5. How do you ensure the color consistency across different batches?
We use spectrophotometers to measure ΔE values during production and maintain strict records. All batches are produced under the same paint formula and substrate specification. The mill test report includes color data for your verification.
6. What kind of installation system do these panels use?
Our metal wall panels are designed for both concealed fastener (standing seam) and exposed fastener (corrugated) systems. We can also provide matching flashing, trim, and fasteners upon request.
7. Are these panels suitable for coastal or high-corrosion environments?
Yes. We recommend using Galvalume substrate (AZ180 or higher) with a premium PVDF coating for maximum corrosion resistance. Additional edge protection options are available.
