The Look of Precious Metal, The Backbone of Steel
For the highest aesthetic and functional demands, CNB provides stainless‑steel‑clad and copper‑clad steel plates. Unlike simple film lamination, these composites are produced by explosive welding or advanced hot‑roll bonding, creating a true metallurgical bond at the interface. This allows the material to be used in pressure vessels, heat exchangers, and structural decorative elements where a permanent, inseparable bond is essential.

Technical Features

• Stainless‑Clad Steel: 304, 304L, 316L cladding on carbon steel base (Q235B, Q345B). Clad thickness 2‑3mm, total thickness 8‑50mm for pressure vessels, or thin decorative sheets (0.3‑0.6mm on SGCC) for elevator doors, columns, and furniture.

• Copper‑Clad Steel: Red copper (T2) or brass clad on steel. Used in luxury copper doors, temple decoration, chemical vessels, and conductive components.

• Bond Strength: Shear strength >210 MPa; no separation under thermal cycles or deep drawing.

Specifications

• Base Metal: Carbon steel, galvanized steel

• Cladding Metal: Stainless steel (304, 316L), copper (T2, brass), titanium, aluminum

• Total Thickness: 0.8mm (decorative) to 50mm (heavy plate)

• Width/Length: Up to 2500mm width, length customized
