A: Ewe, iikhoyili zegalvanized zinokuthi zifakwe, kodwa ingqwalasela ekhethekileyo kufuneka ithathelwe ingqalelo ngenxa yengubo ye-zinc. I-Zinc inokukhupha imfucu eyingozi xa ishushu, ngoko ke umoya ofanelekileyo kunye neendlela zokukhusela ziyimfuneko ngexesha lenkqubo ye-welding.

Umbuzo: Yintoni intsingiselo yesipantshi kwiikhoyili ezenziwe ngamagalvanized?

A: I-Spangle ibhekiselele kulwakhiwo oluyikristale olubunjwe kumphezulu wentsimbi ekhandisiweyo ngexesha lenkqubo yokugalela. Ukubonakala kwe-spangle kunokuchaphazela umgangatho wobuhle bemveliso egqityiweyo, kodwa ayichaphazeli ukuxhatshazwa kwentsimbi.

Umbuzo: Zeziphi iintlobo zentsimbi ezisetyenziselwa ukuvelisa iikhoyili ezenziwe ngegalvanized?

A: Ii-coil ze-galvanized zenziwa ngokuqhelekileyo kwi-carbon-low-carbon or cold-rolled carbon steel, ukubonelela ngesiseko esiqinileyo se-zinc coating. Ukukhethwa kwentsimbi kuchaphazela usetyenziso lokugqibela lwemveliso yegalvanized kunye neempawu zomatshini.

Umbuzo: Liliphi ixesha eliphambili loku-odola iikhoyili ezenziwe ngamagalvanized kwi-warehouse yentsimbi?

A: Ixesha elikhokelayo loku-odola iikhoyili ezinobumba linokwahluka ngokuxhomekeke kumthengisi kunye neenkcukacha zekhoyili ezifunekayo. Ngokubanzi, amaxesha okukhokela anokuqala ukusuka kwiintsuku ezimbalwa ukuya kwiiveki ezininzi, kuxhomekeke ekufumanekeni kwesitokhwe kunye nexesha lokucubungula.

Umbuzo: Iikhoyili zegalvalume zahluke njani kwiikhoyili ezenziwe ngegalvanized?

A: Iikhoyili zeGalvalume zigqunywe nge-aluminiyam kunye ne-zinc, zibonelela ukuxhathisa okufanayo kwe-corrosion kwii-coil ze-galvanized kodwa kunye nokusebenza okuphuculweyo kwiindawo ezithile. I-Galvalume idla ngokukhethwa ukuphahla kunye nezicelo zangaphandle.

Umbuzo: Ngaba kukho iigeyiji ezahlukeneyo ezikhoyo kwiikhoyili ezenziwe ngamagala?

A: Ewe, iikhoyili zegalvanized zifumaneka kwiindidi ezahlukeneyo ze-gauge, ezinokuthi zichazwe ngokweemfuno zesicelo. I-gauge ichaphazela amandla kunye nokuqina kweemveliso ezigqityiweyo ezenziwe kule mibhobho.

Umbuzo: Yintoni ukubaluleka kwenkqubo ye-pickle ekudaleni iikhoyili zegalvanized?

A: Inkqubo ye-pickle ibalulekile njengoko ihlambulula indawo yentsimbi engenanto ngaphambi kokuba ifakwe. Eli nyathelo lisusa nayiphi na i-oxidation okanye i-contaminants, ukuqinisekisa ukuba i-coating ye-zinc ibambelela ngokufanelekileyo kwaye yandisa ukuxhathisa ukubola.
