Tepi yomatira, yomwe imadziwika kuti zomatira, ndi chinthu chomwe chimagwiritsa ntchito nsalu, mapepala, filimu, ndi zinthu zina ngati maziko.Zomatirazo zimagwiritsidwa ntchito mofanana pamwamba pa gawo lapansili, kukonzedwa kukhala mzere, ndiyeno amapangidwa kukhala koyilo kuti apereke.Tepi yomatira imakhala ndi magawo atatu: gawo lapansi, zomatira, ndi pepala lotulutsa (filimu).

Mtundu wa gawo lapansi ndiye mulingo wodziwika bwino wa tepi zomatira.Malinga ndi magawo osiyanasiyana omwe amagwiritsidwa ntchito, matepi omatira amatha kugawidwa m'magulu asanu ndi limodzi: tepi yochokera pamapepala, tepi yopangira nsalu, tepi yotengera mafilimu, tepi yachitsulo, tepi ya thovu, ndi tepi yopanda gawo.

Kuonjezera apo, matepi omatira amathanso kugawidwa malinga ndi mphamvu zawo komanso mtundu wa zomatira zomwe zimagwiritsidwa ntchito.Malinga ndi mphamvu zawo, tepi yomatira imatha kugawidwa mu tepi yotentha kwambiri, yamagulu awiri, tepi yotsekemera, ndi tepi yapadera, ndi zina zotero;Malinga ndi mtundu wa zomatira, tepi yomatira imatha kugawidwa mu tepi yotengera madzi, tepi yotengera mafuta, tepi yosungunulira, tepi yotentha yosungunuka, ndi tepi ya mphira wachilengedwe.Tepi yomatira imakhala ndi ntchito zambiri m'moyo watsiku ndi tsiku wa anthu komanso zochitika zamakampani.Ndi kuwongolera kosalekeza kwaukadaulo wopanga tepi zomatira, ntchito zatsopano zapangidwa mosalekeza za tepi yomatira.Yakula kuchokera ku kusindikiza koyambira, kulumikizana, kukonza, chitetezo ndi ntchito zina kupita kuzinthu zosiyanasiyana zophatikizika monga kutsekereza madzi, kutchinjiriza, conductivity, kukana kutentha kwambiri, kukana dzimbiri, ndi zina zambiri.
