Ukuze unciphise izakhiwo ze-anisotropic zokhuni lwemvelo futhi uqinisekise izakhiwo ezifanayo kanye nokuma okuzinzile, i-plywood ngokuvamile inamathela ezimisweni ezimbili eziyisisekelo zesakhiwo: ukulinganisa; kanye ne-perpendicularity yezintambo ezisezingqimbeni eziseduze. Isimiso sokulinganisa sidinga ukuthi ama-veneers akunoma yiluphi uhlangothi lwendiza emaphakathi ye-plywood ye-symmetry alingane, kungakhathaliseki ukuthi yiziphi izakhiwo zokhuni, ukujiya kwe-veneer, inani lezendlalelo, ukuma kwefayibha, okuqukethwe komswakama, nezinye izici. Ngaphakathi kweshidi elilodwa le-plywood, ama-veneers ohlobo olulodwa nogqinsi angasetshenziswa, kanye nama-veneers ezinhlobo ezahlukene nogqinsi. Nokho, noma yiziphi izingqimba ezimbili ezilinganayo ze-veneer nhlangothi zombili zendiza emaphakathi yokulinganisa kufanele zibe zohlobo olufanayo nogqinsi. Amaphaneli obuso nangemuva avunyelwe ukuthi abe yizinhlobo ezahlukene.
Ukuze i-plywood ivumelane nazo zombili lezi zimiso eziyisisekelo, kufanele ibe nenani eliyinqaba lama-plies. Ngakho-ke, i-plywood ijwayele ukwakhiwa ngezinombolo ezingavamile ze-plies, njengezintathu, ezinhlanu, noma eziyisikhombisa. Amagama ezingqimba ze-plywood yilezi: i-surface veneer ibizwa ngokuthi i-faceboard, i-veneer yangaphakathi ibizwa ngokuthi i-coreboard; ibhodi elingaphambili libizwa nge-topboard, kanti ibhodi elingemuva libizwa nge-backboard. I-coreboard enemicu ehambisana ne-faceboard ibizwa ngokuthi ibhodi eliwumgogodla omude noma ibhodi eliphakathi. Lapho uhlanganisa ibhodi lomgodi lingenalutho, ingaphezulu nebhodi elingemuva kufanele libheke ngaphandle.
