Iyo substrate yesimba yakavharwa simbi sheet inogadzirwa ne zinc-aluminium-magnesium (ZM) alloy coating.Pahwaro hwechinyakare galvanizing tekinoroji, imwe chikamu chealuminium uye magnesium inowedzerwa kuita zinc-aluminium-magnesium alloy coating.Iyo eutectic chimiro chine aluminium uye magnesium inoumbwa mujasi, iyo inobudirira inovandudza kusimba kwekuora uye kuramba kwemamiriro ekunze kwejasi.Iyo ine imwe otomatiki yekuzviporesa basa rekucheka, kukwenya uye kukuvadza kunogadzirwa panguva yesimbi pepa kugadzira, kutakura uye kuisa.Ongororo dzinoratidza kuti mushure memunyu wekupfapfaidza ngura, zvigadzirwa zvekuora zvine magnesium nealuminium zvinoonekwawo pakuchekwa kwendiro yesimbi.Iyo yakaderera conductivity uye dense yemhando yezvigadzirwa zvecorrosion izvi zvinoparadzanisa kucheka kubva kune ambient mvura uye oxygen, ichigadzira inoshanda yekudzivirira layer.Naizvozvo, kunyangwe iyo resin yekuputira yakakuvadzwa, iyo zinc-aluminium-magnesium alloy layer ichine yakanakisa corrosion resistance uye mamiriro ekunze.Kusvika kumwero wakati, izvi zvinodzivirira njodzi dzekuora dzinokonzerwa nekukwenya, kuveura, uye kurova zvinowanzoitika panguva yekuiswa kwesimbi pepa.
