lamevaltsitud metalltoode, mille maksimaalne paksus ja minimaalne laius sõltuvad kokkuleppeliselt metalli liigist ning toote laiuse ja paksuse suhe on üle ligikaudu 50; tavaliselt nimetatakse alla 6,5 mm paksuseid tooteid õhukeplekiks (sheet) ning 6,5 mm paksuseid ja paksemaid paksplekiks (plate) (vt plekk/lehtmetall, õhukeplekk, paksplekk, foolium), a flat-rolled metal product of some maximum thickness and minimum width arbitrarily dependent on the type of metal; it has a width-to-thickness ratio greater than about 50; generally, such flat products under 6.5 mm in thick are called sheets, and those 6.5 mm thick and over are called plates (see: sheets, sheet, plate, foil)
