Gukata aluminiyumu, ibishishwa bidasanzwe bigomba gutorwa. Mubisanzwe, ubwoko bwibintu, ubwoko ， ubunini numubare w amenyo yicyuma kiboneka byose birakenewe.

Icyuma cyihariye kidasanzwe nkicyo cyo guca acrylic, ibiti bikomeye, plexiglass, nibindi ntibikoreshwa rwose, kuko ingaruka rwose ntabwo ari nziza, kandi izangirika vuba, bitari ngombwa. Kuberako icyuma kidasanzwe cyakozwe mbere hakurikijwe gukata ibiranga ibyuma bya aluminiyumu.

Muri byo, hari ibindi bisabwa muguhitamo, nkumubare w amenyo, icyitegererezo nibindi. Nyuma yo guhitamo icyuma kibonerana, menya neza guhitamo icyuma kiboneka gifite amenyo aringaniye, ntabwo ari ubukonje bukonje bwa ceramic, ibyuma byihuta byihuta cyangwa ikindi kintu. Niba uhisemo ibitari byo mu ntangiriro, ntuzabona ibisubizo byiza nyuma.

Muri icyo gihe, ubwoko bwicyuma cyatoranijwe nabwo ni ingenzi cyane, cyane cyane harimo urukurikirane rwibipimo nka diameter yo hanze yicyuma kibisi, aperture, umubyimba, umubare w amenyo, nibindi. Aya makuru afite uruhare runini kuri Ingaruka. Niba hari ihuriro ryatoranijwe nabi, ingaruka zo kugabanya igice runaka ntizishimishije.

Kurugero, niba diameter yinyuma yatoranijwe yabonetse ari nini cyane, ibikoresho ntibishobora gushyirwaho; niba diameter yo hanze ari nto cyane, ubushobozi bwo gukata buzacika intege, kandi ntibishobora gucibwa icyarimwe. Kubijyanye n'ubunini bw'icyuma kibisi, bifitanye isano n'ubuzima bwa serivisi. Niba ari muremure, igipimo cyigihombo kizagabanuka, kandi ubuzima bwikibabi cyongerewe uko bikwiye. Ariko, niba bidakenewe igihe kinini, ntabwo ari ngombwa guhitamo icyimbye cyane.
