PRANCE metalwork is a leading manufacturer of metal ceiling and facade systems.
what is the difference between metal panels and acm panels
Single-skin metal panels are fabricated from a single layer of aluminum or steel, whereas ACM panels consist of two thin aluminum skins bonded to a core material. This fundamental difference yields several performance distinctions in aluminum ceiling and facade applications:
Rigidity and Flatness
ACM panels exhibit superior stiffness and planar flatness due to the composite core. Single-skin panels can ripple or warp over large spans.
Weight
ACM panels combine light weight with high bending strength. Single-skin sheets may require thicker gauges to achieve similar rigidity, increasing weight.
Formability
The composite core allows ACM panels to be bent, curved, and perforated with less risk of cracking. Single-skin panels have limited formability and higher risk of buckling.
Appearance
ACM panels provide uniform finishes on both faces and hidden fastener installations for clean visual effects. Metal panels often use exposed ribs or concealed-fastener flange designs.
Acoustic and Thermal Performance
ACM cores can enhance sound dampening and provide minimal insulation value. Single-skin metal panels offer negligible acoustic benefits without additional backing.
Overall, ACM panels deliver enhanced performance, versatility, and aesthetics compared to single-skin metal panels in modern aluminum ceiling and facade systems.
