Iibhodi ezinamaziko zihlala zihlelwa ngeendlela ezahlukeneyo ngokwendawo yesicelo, ukuphakama kwamaza ebhodi, ukwakheka komjikelo, kunye nezinto.
Iindlela zokuhlela eziqhelekileyo zezi zilandelayo:
(1) Ngokutsho kokuhlelwa kweengxenye zesicelo, ihlukaniswe kwiipaneli eziphahleni, iipaneli zodonga, iiplanga zomgangatho kunye neepaneli zesilingi. Ekusetyenzisweni, ipleyiti yentsimbi yombala isetyenziswa njengebhodi yokuhombisa eludongeni ngaxeshanye, kwaye isiphumo sohombiso soyilo sinoveli kwaye sisodwa.
(2) Ngokokuhlelwa kokuphakama kwamaza, yahlulwe ibe yipleyiti ephezulu yamaza (ukuphakama kwamaza ≥70mm), ipleyiti yamaza ephakathi kunye nepleyiti ephantsi yamaza (ukuphakama kwamaza <30mm)
(3) Ukwahlula ngokwezinto eziphathekayo - zahlulwe kwi-hot-dip galvanized substrate, i-hot-dip galvanized substrate ye-aluminium, kunye ne-hot-dip galvanized substrate ye-aluminium.
4 Amagqabi aphakathi kunye namaza aphakamileyo anezinki asetyenziswa njengezigqubuthelo zomgangatho; iibhodi zamaza amaza aphantsi zisetyenziswa njengeepaneli zodonga.
