3. Product Applications

3.1 Architectural Decoration

Used in roof panels, wall cladding, door/window frames, and interior decorative components. The brilliant surface enhances aesthetic appeal, while corrosion resistance ensures long-term durability in diverse climatic conditions.

3.2 Apparel & Ornament Industry

Processed into high-end apparel decorations, badges, and accessories. Easy chemical coloring and excellent ductility support versatile design customization, meeting luxury brand requirements.

3.3 Infrastructure Engineering

C11000 water-stop strips are engineered for construction joints in civil engineering. They deliver reliable waterproofing and sealing performance, ensuring structural anti-seepage in bridges, tunnels, and buildings.

3.4 General Manufacturing

Regular strips serve as raw materials for electronic components, hardware parts, and precision instruments. Stable structural performance and (for copper) excellent conductivity meet diverse production needs.

Note: All parameters are tested under standard conditions (23?, 1 atm). Custom slitting, tempering, and surface treatments are available. Contact our technical team for ASTM compliance certificates or samples.
