Copper Roofing Panels 1000mm Width 0.8mm Thickness Mill Finish ASTM B370 Compliant
Product Spotlights
As a dedicated manufacturer with over 25 years of experience in metal processing, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Copper Roofing Panels – 1000mm width, 0.8mm thickness, mill finish, and fully compliant with ASTM B370. Our factory, established in 1998 and exporting to over 15 global markets, brings precision engineering and rigorous quality control to every panel we produce. These copper panels are designed to deliver exceptional durability, natural beauty, and long-term performance for residential, commercial, and industrial roofing projects. Backed by annual export values exceeding US$5 million, we ensure that each batch meets the highest international standards.
Our copper roofing panels are crafted from high-purity copper (C11000/C10200), offering excellent corrosion resistance, malleability, and a distinctive aesthetic that ages gracefully over time. The 1000mm width reduces the number of seams required, speeding up installation and minimizing potential leak points. With a thickness of 0.8mm, these panels strike the perfect balance between strength and workability, making them suitable for both flat and pitched roofs. The mill finish provides a natural copper surface that develops a protective patina over years of exposure, eliminating the need for painting or additional coatings.

Advantages & Customer Benefits
- Enhanced Aesthetics: The natural copper mill finish provides a warm, elegant look that complements both modern and traditional architecture. Over time, the patina evolves, offering a unique and attractive appearance.
- Superior Weather Resistance: Copper forms a protective oxide layer that resists moisture, salt spray, and UV radiation, making it ideal for coastal, humid, or extreme climate regions.
- Low Maintenance: No need for painting, sealing, or coating; the natural patina acts as a self-protecting layer, reducing long-term maintenance costs.
- Eco-Friendly & Recyclable: Copper is 100% recyclable without losing its properties, contributing to LEED points and sustainable building practices.
- Cost-Effective Lifecycle: Although initial investment is higher than steel or aluminum, copper roofing’s 50–100 year lifespan and minimal maintenance deliver excellent return on investment.
- Versatile Applications: Suitable for roofing, wall cladding, gutters, flashings, and decorative elements – both residential and commercial.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between mill finish and other finishes?
A: Mill finish is the natural surface of copper as it comes from the rolling process – uncoated and untreated. It will develop a patina over time (dark brown to green). Other finishes like pre-patinated or coated are available upon request, but our standard panels are mill finish. -
Q: Can these panels be used for standing seam metal roofing?
A: Yes, these 1000mm wide panels are commonly used in standing seam systems. They integrate well with standard seamers and clips. We can also provide panels with pre-formed edges if needed. -
Q: How do I prevent galvanic corrosion when using copper with other metals?
A: Copper should be separated from dissimilar metals (e.g., steel, aluminum) using dielectric barriers or flashings. We recommend consulting with a roofing professional for proper detailing. -
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ is typically 500 square meters for standard sizes. For custom lengths or special requirements, MOQ may vary – please contact us for details. -
Q: Are samples available before placing a bulk order?
A: Yes, we offer free samples of 300mm x 300mm or along with freight charges. You can request samples to evaluate the color, thickness, and finish. -
Q: How long does shipping take to North America?
A: Typical sea freight from Tianjin or Qingdao to major US West Coast ports takes about 20–25 days. For East Coast ports, it may take 30–35 days. We can arrange faster shipping if needed. -
Q: Does the panel come with a warranty?
A: We offer a limited warranty against manufacturing defects. The exact warranty period can be discussed during order confirmation. Copper's natural patina is not a defect. -
Q: Can I get panels with a different thickness or width?
A: Yes, we can customize thickness from 0.5mm to 1.2mm and width from 600mm to 1200mm. Please specify your requirements when inquiring.
