I-Model T4200 iwuhlu lwamaphrofayili e-aluminium eklanyelwe ukuqeda, ukuvala nokuvikela izinga lamathayela, imabula, igwadle, ukhuni nezinye izinhlobo zephansi.Ngenxa yokuguquguquka kwayo, i-Model T4200 nayo iphelele njengejoyinti lokuhlukanisa, isibonelo, phakathi kwamathayela aphansi kanye nokhaphethi noma ukhuni, njengephrofayili ye-perimeter equkethe ama-doormats, nokuvikela izinyathelo zamathayela e-ceramic namapulatifomu.Ingxenye ekubukweni kwephrofayela iboleka ubuhle phansi kodwa ayihlaseli, ihlangana ngaphandle komthungo ebusweni.
Imodeli ye-T4300 yochungechunge (iphrofayili ye-T-shape) iwuhlu lwamaphrofayili akhethekile wokuqaqa, ukuvikela kanye nokuhlobisa izinga laphansi ngezinhlobo ezahlukene zezinto, njengamathayela, imabula, igwadle noma ukhuni.Lolu hlu lwamaphrofayili ezitezi zokuphakama okufanayo lungasetshenziswa futhi ukufihla noma yikuphi ukungapheleli ngenxa yokusika noma ukubekwa kwezinto ezihlukene.I-cross-section ethile yenza i-Model T4300 ibe ilungele ukuvala noma yikuphi ukuthambekela okuncane okubangelwa ukuhlangana kwezinhlobo ezahlukene zamaphansi.I-cross-section emise okwe-T iphinde idale ihange eliphelele elinama-sealant nama-adhesive.
Uchungechunge lwe-Model T4400 luwuchungechunge lwamaphrofayili e-threshold afihla noma yikuphi ukungapheleli kokusika noma ukubeka ezigabeni zaphansi zezinto ezahlukahlukene, njengokuxhunywa kokhuni namathayili.I-convex surface yalawa maphrofayili isiza ukulungisa noma yimuphi umehluko ongu-2-3mm ngobude phakathi kwezinhlobo ezimbili zephansi.Ngaphezu kwalokho, kulula kakhulu ukuzibeka nge-adhesive noma nge-screw-fixing.
Imodeli ye-T4500 yochungechunge iwuchungechunge lwamaphrofayili e-threshold ane-flat cross-section, eklanyelwe ukufihla ukujoyina phakathi kwezingxenye ezimbili zephansi lezinto ezahlukene.Ngaphandle komumo oyi-convex, ingasetshenziswa ngaphansi kweminyango futhi indawo engashibiliki egoqekile isiza ukukhulisa ukuphepha.Imodeli T4500 itholakala aluminium nobubanzi kusuka 15mm kuya 40mm.
