Ko te mekameka tuku GL i hangaia hei paerewa ISO/BS/ANSI, ko te manaakitanga tino pai i puta mai - i maioha mo tona kounga, ohaoha- kua nui ake te whakaputanga.
Kei roto i ta maatau momo mekameka nga tauira tino rongonui penei i te roera roera (kotahi, takirua me te toru) me nga pereti taha tika, te raupapa taumaha, me nga hua o te mekameka kawe kawe, te mekameka ahuwhenua, te mekameka wahangu, te mekameka taima, me te maha. etahi atu momo ka kitea i te raarangi. I tua atu, ka whakaputahia e matou he mekameka me nga taapiri me nga pikitia a nga kaihoko me nga whakaritenga.
Mo nga taonga hangahanga, ka tukuna nga mekameka GL ki te rino me te kowiri tira (mo te mahi i roto i nga taiao kino, me te kai, nga hua matū me nga rongoa), te rino whakakikorua nickel (e tika ana mo te mahi o waho), te zinc whakakikorua, te rino piauau ranei.
I te wa o te mahi whakangao, ka whakamahia e matou nga mana tino kaha ki runga i nga waahanga pereti hono, te whakakorikori me te peening pere, nga whakamatautau i mua i te taumaha me te pakeke kia pai ai te kounga.
