Izinkomba zokukhetha I-beam le-Amerika fokweni ukutholwa kwazo

I-American Standard I beam iyisilinda esetshenziswa kakhulu esekwa imikhumbi, imicwaya, ukwenza imikhina kanye nezinye izinhawu.

Ukukhetha ukulinganisa

Ngokwesicelo sekuhlalwa kanye nezidingo zokudizajn, khetha leli linganiso. I-American Standard steel I beam inezinhlobo eziningi, njenge W4×13, W6×15, W8×18, nj.sq. Linye izingxenye iyachaza ubukhulu bendawo yokuphakama nebwelo.

Ukukhetha Amathuluzi

I-American Standard I-beams ngokuvamile zenzelwa ngokwezindlela zokwenza izilinda. Xa ukhetha, qaphela ubukhona nobukhosi bezinhlobo ukuthi kuyafaka imiphakathi yekusebenzisa.

Ukuphathwa Kwemvelo

Inqanawe yamathambo we-American Standard I-beam ikhonakala ukuthiweni ngokwehliswa noma ukuphitha ukuze kuvikeleke kakhulu. Uma kusotha, ungalandela inqubo yokuthiweni kungaba neyodwa ukulingana nezimo zokumelene nezinye izimo.

Ukukhetha kweSithunzi

Khetha izinkhuzo eziphumelelayo nezineke ukuthenga amathambo we-American Standard I-beam ukuze uhlangabele kakhulu kwezinhlobo nezisevisi zemva kwekho. Ungabheka izinkomba evela kumathketi, imininingo yesiphiwo noma izinye izinkomba ngokukhetha.

Ukuphelela Ukubuyiselwa

Ngaphambi kokuthenga, ungafula isiphiwo ukuthiwe ukhokhe ishethemba sokulinganiswa nezithuba zokulungiswa ukuze uhlangabele ukuthi i-American Standard I-beam ethengile ifakwe kakhulu kwezinye izimo nezidingo.

Ukuhlangabele ukuthi i-I-beam ethengile ifakwe kakhulu kwezimo zaseMerika, ungaqonda lezi zindlela zilandelayo:

Bheka izimo ezinhle zaseMerika

Ukuqonda izistandela ze-US efanayo, njengama-ASTM (American Society for Testing and Materials) izistandela, ukuze uqonde izi-specification fakwe izi-performance eziqinisekisiweyo kwi ibe yamagama.

Khetha aba-supplier abaqinisekisiweyo

Khetha aba-supplier abanezinhlobo yobungqina nezinhlobo zokuphucula ukuze iqinisekise ukuthi i-beam yamagama eyakhiwa yabo iyafaka amathuluzi we-American Standard.

Nika ama-certificate nezimemo zokuvikwa

Hlola aba-supplier ukuthenjwe ama-certificate wokubiloko nezimemo ezincazelo zokuvikwa kwezinye zezinhlanzi zokwenza i-steel i beam ukuze iqinisekise ukuthi ziyafaka amathuluzi we-AFSL.

Qinisekisa ukuvikwa kwemiboniso

Ungakhetha ukuthatha imiboniso yezinye zezinhlanzi ezikhethiweyo fakwe ukuvikwa ukuthi izi-properties zazo nezinhlobo zazo zokuchemikhulu ziyafaka amathuluzi we-AFSL ngokwenza ama-laboratory tests nezinye izivikelo.

Thulela usizo kweqembu lokuvikwa le-tjirdi

Inkampani yokuvikwa ye-tjirdi yokuqaphela kungenzeka ukuthi ivikwe nekuhlolwe i-beam zamagama ezikhethiweyo ukuze iqinisekise ukuthi iyafaka amathuluzi we-AFSL.

Beke kumaqondo nezindaba zabo zokugcina

Ungabeke kumaqondo nezindaba zabo zokugcina ukuze ubone lokho abathiwe ngokuhlanganisa noba kakhulu ngokunikezwa kwezindawo neqoqa lezinto ukuze wenze ukhetho olungileyo lokuthenga.
