Steel me tuhinga ona

Ko tētahi taua rauemi ko te parahi i ahakoa tona taimaha (kiato toharite = 7860 kg / mita pūtoru) ngā marama, kua nga āhuatanga e tika ana mō te whakapaipai hanga. I roto i tēnei tuhinga ka arotahi tatou i runga i te momo o ngā hua maitai pērā i ngā wāhanga maitai hurihia. I roto i ngā, ka kia whakaaro reira kokonga whakarewa

Na, he aha te mea te reira?

Metal kokonga - ko te momo o ngā wāhanga hurihia. Kei te whānui whakamahia te reira i roto i te hanga. whakarewa Area-waho, he he kurupae L-āhua, e ai kia hanga o ngā momo o te maitai.

koki whakarōpū

• Piko (raraunga tirohanga whiwhi i roto i te whakamahi o te mīhini pukapuka hanga motuhake). e kore e ēnei koki whakamahia hei wāhanga o te hanganga tautoko, engari anake i roto i te wā i reira kahore he hiahia ki te pato'ii te pikaunga teitei, me te te taumata tiketike o te mauroa me te tika.

Hei whakanui i te kaha me te ātete ki awenga waho, kia kitea ai te whakarewa rohe galvanizing tukanga.

mutunga

tuku te mākete hou ki te whakarewa kiritaki koki pea katoa, te rahi o e tei runga i te momo o te maitai e i whakamahia i roto i tona ahumahi. Tikanga, te raraunga i homai i roto i te tepu hāngai (i runga i te rahi o te kokonga rārangi - ona raraunga taimaha me te rīpene kiato).
