Ibintu bigira ingaruka kumubyimba wibyuma bya zinc bifata cyane cyane: ibice byicyuma cyo gusya ibyuma, ubukana bwubuso bwicyuma cya feri, ibirimo nogukwirakwiza ibintu bikora silicon na fosifore mugusya ibyuma, guhangayikishwa imbere kwicyuma, hamwe nuburinganire bwa geometrike yibikorwa byicyuma. Ibipimo ngenderwaho mpuzamahanga nu Bushinwa bishyushye bigabanijwemo ibice ukurikije ubunini bwisahani. Impuzandengo yubunini hamwe nuburinganire bwaho bwa zinc bigomba kugera kubyimbye bijyanye kugirango hamenyekane imikorere yo kurwanya ruswa ya cinc. Igihe gisabwa kugirango ugere kubushyuhe bwumuriro hamwe na zinc-fer yo guhanahana kuringaniza ibyuma byo gusya ibyuma byububiko butandukanye buratandukanye, kandi ubunini bwikibumbano bwakozwe nabwo buratandukanye. Impuzandengo yikigereranyo cyo gutwikiriye mubisanzwe ni agaciro k'uburambe mu nganda hashingiwe ku buryo bwavuzwe haruguru, kandi ubunini bwaho ni agaciro k'uburambe busabwa kugira ngo harebwe ikwirakwizwa ry'uburinganire bwa zinc hamwe n'ibisabwa kugira ngo ruswa irinde ruswa. Kubwibyo, igipimo cya ISO, igipimo cy’abanyamerika ASTM, igipimo cy’Ubuyapani JS hamwe n’Ubushinwa bifite ibisabwa bitandukanye gato ku bunini bw’uburinganire bwa zinc, busa. Ukurikije ibivugwa muri hot-dip galvanizing isanzwe GB B 13912-2002 ya Repubulika yUbushinwa. Ibipimo bya zinc kubicuruzwa bishyushye bishyushya ibyuma bisya ni ibi bikurikira: Kubyuma bishyushye byibyuma bishyushye hamwe nubunini burenze cyangwa bingana na 6mm, impuzandengo ya zinc igereranije yubushyuhe bwa gravine yicyuma igomba kuba irenze microni 85, naho uburebure bwaho bugomba kuba burenze microni 70. Kubyuma bishyushye byashyizwemo ibyuma bifite uburebure buri munsi ya 6mm kandi birenze 3mm, impuzandengo ya zinc itwikiriye ibyuma bishyushye bigomba gushyirwa hejuru ya micron 70, naho uburebure bwaho bugomba kuba burenze microni 55. Kubyuma bishyushye bishyushye byibyuma bifite uburebure buri munsi ya 3mm kandi birenga 1.5mm, impuzandengo ya zinc itwikiriye hejuru yicyuma gishyushye kigomba kuba hejuru ya microne 55, naho uburebure bwaho bugomba kuba burenze microni 45.

Ubunini bwikibiriti gishyushye gishyizwe hejuru yicyuma kigena imikorere yo kurwanya ruswa yo gusya ibyuma. Abakoresha barashobora guhitamo umubyimba wa zinc uri hejuru cyangwa munsi yubusanzwe. Biragoye kubona igifuniko kinini mubyakozwe mu nganda zibyuma byoroshye kandi bifite ubuso butarenze 3mm. Byongeye kandi, umubyimba wa zinc utagereranijwe nubunini bwicyuma gifata ibyuma bizagira ingaruka kumubano uhuza igifuniko na substrate hamwe nubwiza bwikigaragara. Igicu kibyibushye cyane kizatera igifuniko kugaragara nabi kandi byoroshye gukuramo. Gusya ibyuma ntibishobora kwihanganira kugongana mugihe cyo gutwara no kwishyiriraho. Niba hari ibintu byinshi bya silicon na fosifore mubikoresho fatizo byo gusya ibyuma, biragoye cyane kubona igifuniko cyoroshye mubikorwa byinganda. Ni ukubera ko ibintu bya silikoni biri mubyuma bigira ingaruka muburyo bwo gukura bwurwego rwimyunyu ngugu hagati ya zinc na fer, bizatera ((icyiciro cya zinc-fer alloy layer layer) gukura byihuse kandi (hejuru yubuso, bikavamo igipfundikizo kijimye kandi kijimye, bigatuma habaho ibara ryumukara hamwe nubusembwa bubi. Byerekanwe muburyo bushyushye bwa galvanizing yo gusya ibyuma nigiciro cyingirakamaro cyatanzwe nyuma yumubare munini wubushakashatsi, hitabwa kubintu bitandukanye nibisabwa, kandi birumvikana.
