Steel grating plate, inozivikanwawo sesimbi grating plate, imhando yechigadzirwa chesimbi chinoshandisa simbi yakati sandara kuyambuka kuronga pane imwe nzvimbo uye nembariro dzakachinjika, uye inobatanidzwa kuita sikweya grid nepakati. Inonyanya kushandiswa kugadzira mavharo emugero, simbi yechimiro chepuratifomu mahwendefa, simbi manera nhanho mahwendefa, nezvimwewo. Mazariro akachinjika anowanzo gadzirwa neakamonyoroka sikweya simbi.
Simbi grating mahwendefa anowanzo gadzirwa nekabhoni simbi uye ane inopisa-dip galvanized pamusoro, izvo zvinogona kudzivirira oxidation. Inogonawo kugadzirwa nesimbi isina tsvina. Iyo simbi grating ndiro ine zvivakwa zvakaita semhepo, kuvheneka, kupisa kupisa, anti kutsvedza, uye kuputika-chiratidzo.
