Mu rwego rwo kunoza umutekano w'inyubako, Hong Kong yasobanuye neza amabwiriza yose agenga ikoreshwa ryaimirundo y'ubutaka ya galvanised: ibicuruzwa bifite ubugari bwa zinc urwego rwa ≥ 85 μ m kandi byujuje ibisabwa na GB/T 13912 bigomba gutoranywa. Inyigo z’ubutaka zigomba gukorwa mbere yo kubaka, kandi abakozi bemewe bagomba gukoresha ibikoresho byihariye mu gushyiraho ibintu bisanzwe, kugenzura neza uburebure n’ubujyakuzimu bw’aho bashyingura. Nyuma yo gushyiraho, ni ngombwa gupimwa mu buryo bworoshye no gukanda ndetse no kugenzura ubuziranenge bw’inkongi. Ibicuruzwa bidafite ubuziranenge birabujijwe byimazeyo kwinjira aho hantu kugira ngo hirindwe ingaruka mbi z’umutekano ziva aho byaturutse.

Hong Kong yashyizeho uburyo bw'igihe kirekire bwo kugenzuraimirundo y'ubutaka ya galvanised, bisaba igenzura rihoraho ry'ibice byagaragaye, kongera inshuro nyuma y'ikirere kibi, no gusana ku gihe ingese n'ibyangiritse ku rukuta rwa zinc. Muri icyo gihe, shyiraho igitabo cy'imikoreshereze y'ibikoresho, usobanure neza igihe ntarengwa cy'imyaka 30 y'akazi, kandi utange itegeko ryo gusimbuza ibirundo by'ubutaka byarangiye cyangwa byangiritse. Guverinoma izashimangira kandi igenzura ryihariye n'amahugurwa ku bakora kugira ngo bongere inyungu zabo mu gukumira ingese, gukumira inkongi z'umuriro, no kudahungabana.
