Stucco Embossed Aluminum Sheet for Decoration, Insulation & HVAC
Aluminum embossed sheet 1050 1060 1100 offers excellent corrosion resistance, formability, and thermal performance, ideal for insulation jacketing, HVAC ducts, refrigeration, decoration, and packaging. Available in stucco and other patterns, thickness 0.25–2.0 mm, widths up to 1600 mm, with stable surface quality and consistent embossing depth.
Aluminum embossed sheet in alloys 1050, 1060, and 1100 belongs to the 1xxx series commercially pure aluminum. Embossed (usually stucco) texture is mechanically rolled onto the surface, creating a decorative, slip‑resistant, and rigidity‑enhancing pattern.
These grades are widely used in:
- Thermal insulation jacketing for pipes, vessels, and equipment
- HVAC air-conditioning ducts and ventilation systems
- Refrigeration and cold storage lining
- Decorative panels and cladding for buildings and interiors
- Packaging and automotive heat shields
1050/1060/1100 share similar properties: high thermal conductivity, outstanding corrosion resistance, excellent formability, and non-toxic, lightweight characteristics.
