Definition
Corrugated metal decking — a brand name (PT Cladding) that has become generic for corrugated galvalum or steel sheet with a trapezoid profile. Spandek is lighter and cheaper than genteng metal, used for industrial buildings, carports, and temporary structures. It provides no insulation but excellent rapid weather protection.
Example
An Indonesian warehouse or factory typically uses spandek roofing over steel trusses — the corrugated profile spanning 1.5–2 metres between purlins, fastened with self-tapping screws, providing watertight coverage at minimal cost.
