Nigute inshundura zo kurinda umuhanda zishobora gukoreshwa igihe kirekire mugukoresha hanze? Urushundura rwo kurinda umuhanda rukoreshwa cyane muri iki gihe, ariko kurwanya ruswa y'urushundura rwamye ruteye impungenge. Vuba aha, hot-dip galvanizing yinzira zo kurinda umuhanda zarakozweho ubushakashatsi. Ibi ntibitanga gusa ireme kandi ryongera ubuzima bwa serivisi. Urushundura rugoramye rwa mpandeshatu rwakoreshejwe cyane mukurinda imitako kumihanda nyabagendwa, umuhanda munini, gari ya moshi, ibibuga byindege, inganda, inganda, aho gutura, ibyambu na terminal, oase ya komini, ibitanda byindabyo zo mu busitani, na oase. Urubuga rwa Guardrail nuburyo bwo gushiraho umurongo wa interineti no guhinduka ibicuruzwa byateye imbere. Igabanijwemo cyane mubyiciro bitatu: galvanised, spray-coated and dip-coated. Iki gicuruzwa gisudira hamwe nu cyuma cyiza cyo hasi cya karubone. Ibintu byangirika birimo amashanyarazi, gusya bishyushye, gutera plastike, no kwibiza plastike. Ibicuruzwa nibyiza, bikomeye kandi byangiritse neza. Inzobere muri gari ya moshi, umuhanda munini, hamwe n’imyanda, ifite ibiranga kuramba, ubwiza, icyerekezo cyagutse, nuburyo bwiza bwo kurinda.
Urubuga rwa guardrail nigicuruzwa cyo kurinda umwuga. Biraramba, byiza, bifite icyerekezo cyagutse, kandi bifite uburyo bwiza bwo kurinda. Umubiri wa mesh ushyirwa muri beto nkimwe mu nkingi, kandi muri rusange, igiciro cyumushinga ni gito. Imbaraga-nyinshi muri rusange itajegajega, ibara ryumubiri wibara rya plastike rifite imbaraga zo kurwanya ruswa kandi bigira ingaruka nziza, bigatuma umurizo wa net umurizo uhuza neza kandi mwiza. Ibiranga ibicuruzwa: kurwanya ruswa, kurwanya gusaza, kurwanya ikirere, kurwanya izuba, nibindi. Kurwanya ruswa, muburyo bwo gukwirakwiza amashanyarazi ashyushye, gutera plastike, no kwibiza plastike, bikoreshwa cyane nkindi nzitizi kumihanda minini ya gari ya moshi ifunze, kandi ikoreshwa mumarembo muri zone ziterambere. Iki gicuruzwa gikoreshwa cyane cyane mu bwigunge no kurinda impande zombi za gari ya moshi. Nibicuruzwa byafunzwe kubibanza byumwuga wa gari ya moshi. Ifite ibiranga kuramba, ubwiza, iyerekwa no gufungura, kandi ifite ibikorwa byiza byo kurinda. Uruzitiro rwose rwa gari ya moshi rwubatswe hifashishijwe gusuka beto, irinda umutekano, inkingi zisukuye, igiciro gito cyumushinga kandi ni byose. Imbaraga-nyinshi muri rusange itajegajega, ibara ryumubiri wibara rya plastike rifite imbaraga zo kurwanya ruswa kandi bigira ingaruka nziza, bigatuma umurizo wa net umurizo uhuza neza kandi mwiza.
Mugihe ushyira urushundura, ishami ryubwubatsi rigomba gufata neza ibishushanyo bitandukanye byubwubatsi hamwe nimyanya nyayo yimiyoboro itandukanye yashyinguwe kumuhanda. Mugihe cyubwubatsi, ibyangiritse kubikoresho byubutaka ntibyemewe. Niba umuhanda wa gari ya moshi urinzwe mu nkingi, Iyo ari ndende cyane, inkingi ntigomba gukururwa no gukosorwa. Urufatiro rugomba kongera gushyirwaho mbere yo gutwara, cyangwa umwanya winkingi ugomba guhinduka. Mugihe wegereye ubujyakuzimu mugihe cyubwubatsi, hagomba kwitonderwa kugenzura ubukana bwinyundo. Kubirindiro bya gari ya moshi, hagomba gushyirwaho flanges, kandi hagomba kwitonderwa aho flanges zumuyoboro urinda umutekano no kugenzura ubutumburuke bwo hejuru bwinkingi. Umuyoboro wa Guardrail ni umushinga wo gushyiraho ibikoresho byumutekano wa gari ya moshi nigice cyingenzi cyubwiza bugaragara bwimihanda. Ubwiza bwimbere bwumuhanda wa gari ya moshi urinda ibikoresho bibisi no gutunganya. Imiterere yacyo igaragara kubikorwa byubwubatsi. Mugihe cyubwubatsi, tugomba kwitondera guhuza imyiteguro yubwubatsi hamwe n umushoferi wikirundo, guhora tuvuga uburambe, no gushimangira imicungire yubwubatsi, kugirango ubwiza bwubwubatsi bushoboke. Ibicuruzwa byumuhanda urinda ibara bifite amabara meza, isura nziza no kurengera ibidukikije, kurwanya ruswa cyane, kurwanya umunyu, kurwanya ubushyuhe nubushyuhe, guhangana nikirere, amabara meza, imbaraga nyinshi, ubuzima bwa serivisi ndende, hamwe no gufata neza no gusana.
Kubyerekeranye nigiciro cyo kuvura gishyushye cyo kuvura inshundura zo mu muhanda: ikiguzi cyo gushyushya imishwarara yo gukumira ingese kiri munsi yikiguzi cy’andi marangi; uburebure bwurushundura rwumuhanda: mubidukikije byumujyi, ubusanzwe bushyushye-dip galvanised anti-rust Ubunini bw ingese burashobora kumara imyaka irenga 50 budasanwa; mu mijyi cyangwa mu nyanja, ibisanzwe bishyushye-bigabanya anti-rust birashobora kumara imyaka 20 bitasanwe; ubwizerwe bwurushundura rwinzira nyabagendwa ukoresheje ubu buryo bwo kurwanya ruswa nibyiza: Igice cya galvanised gihujwe nicyuma kandi gihinduka igice cyicyuma, bityo uburebure bwikigero bwizewe ugereranije;
Igipfundikizo cyurushundura gifite uburebure burambye: igipande cya galvanise kigizwe nuburyo bwihariye bwa metallurgjique, bushobora kwihanganira ibyangiritse mugihe cyo gutwara no gukoresha; uburinzi bwihariye: buri gice cyigice cyashizweho gishobora gushyirwaho zinc, kabone niyo gishobora kurindwa muburyo burambuye mubiruhuko, inguni zikarishye nahantu hihishe; hot-dip galvanizing ya netrail izigama umwanya n'imbaraga: inzira ya galvanizing iroroshye kuruta ubundi buryo bwo kubaka coating, kandi irashobora gukumira ishyirwaho ryizamu ahazubakwa. Igihe gisabwa cyo gushushanya hejuru. Ubushuhe bushyushye bwa galvanisiye bwera kandi bufite zinc nyinshi, zihenze gato. Muri rusange, ibishishwa byavanze bifite amabara menshi kandi bifite imiti myiza yo kurwanya ruswa.
