Igiceri gisize amabarasubstrate

Substrate ya electro-galvanised: igifuniko cyoroshye, kandi kurwanya ruswa kwayo ntabwo ari byiza nkibya hot-dip galvanised substrate;

Hot-dip galvanised substrate: Isahani yicyuma yoroheje yinjizwa mubwogero bwa zinc yashongeshejwe kugirango igipande cya zinc gifatanye hejuru.Isahani ya galvanised ifite gufatana neza no gusudira neza.
Gushyushya-Al-Zn substrate:
Igicuruzwa gishyizwe hamwe na 55% AL-Zn, gifite imikorere myiza yo kurwanya ruswa, kandi ubuzima bwacyo bukubye inshuro zirenga enye icyuma gisanzwe.Nibicuruzwa bisimbuza urupapuro.

Igiceri cya PPGI cyangwa igiceri cya PPGLIbiranga:

(1) Ifite igihe kirekire, kandi irwanya ruswa irashobora kuba ndende kuruta icyuma gisya;

.
(3) Ifite amashanyarazi meza;
(4) Ifite imikorere yo gutunganya no gutera spray isa nimpapuro zicyuma;
(5) Ifite imikorere myiza yo gusudira.
(6) Ifite igiciro cyiza-cyimikorere, imikorere irambye nigiciro cyapiganwa cyane.
