A METHOD OF FORMING A STRUCTURAL PANEL

摘要

A method of forming a structural panel (58) which includes the steps of forming a plurality of transversely spaced apart longitudinally extending expandable or perforated zones (54) in a sheet material (32) and deforming the sheet material to form a corrugated member. The corrugated member then has alternating oppositely disposed transversely spaced apart longitudinally extending crest regions (44) and connecting regions connecting adjacent crest regions to each other. The connecting regions are formed at least partially by the expandable or perforated zones (54). An apparatus (10) for forming such a structural panel (58), and a structural panel (58) when formed in accordance with the method is also provided.
