T1: MeneneTarin bututun ƙarfe na ASTM A252?
Su bututun ƙarfe ne da ake amfani da su wajen haƙa ƙasa, tushe, gadoji, tashoshin jiragen ruwa, da kuma wuraren aikin gini.
Q2: Menene maki a hannun jari?
Aji na 1, 2, da 3 - Gr.1 ya dace da ɗaukar nauyi mai sauƙi, Gr.2 aikace-aikace ne don gini gabaɗaya, Gr.3 busarwa mai nauyi.
Q3: Nawa ne girman da kuke da shi?
Diamita: 4"–24" (114–610mm)
Kauri daga bango: 5–25mm
Tsawon: 6-12m ko kuma gwargwadon buƙatunku
T4: Shin an yi wa waɗannan tarin fenti magani?
Eh - An yi amfani da galvanized mai zafi, an shafa shi da fenti ko kuma an yi masa fenti da epoxy don kare tsatsa.
T5: Wane irin takardar shaida ake bayarwa?
Duk tarin sun haɗa da MTC Binciken ɓangare na uku yana samuwa.

An haɗa shi da madaurin ƙarfe
Isarwa mai yawa ko pallets na katako.
Tare da iyakoki na ƙarshe da maganin hana tsatsa
Q7: Zan iya samun girma dabam dabam?
Eh za mu iya ba ku diamita na musamman, tsayi da maki don aikinku.
Q8: Yadda ake zaɓar maki mai kyau?
Dangane da ƙarfin kaya, yanayin ƙasa da amfani da gini. Taimako daga injiniyanci.
Q9: Menene lokacin isarwa na yau da kullun?
Kwanaki 15-30, ya danganta da yawa da kuma keɓancewa.
