-
Intengo yefekthri yamantongomane aphezulu enziwe e-China
Amantongomane e-Hex (abuye abizwe ngokuthi amantongomane e-hex aqediwe) atholakala ku-ASTM A563-A futhi ahambisana namabhawodi ensimbi ekhabhoni ephansi njenge-ASTM A307, ASTM F1554 grade 36, SAE grade 2, kanye ne-AASHTO M183.Amantongomane e-SAE ebangeni lesi-5 kanye nebanga lesi-8 nawo ayatholakala ngephethini eqediwe.Njengoba i-hot-dip galvanizing ngokuvamile yengeza u-2.2 kuya ku-5 wamamilimitha wogqinsi engxenyeni ewuchungechunge yesibambiso, amantongomane e-hex afakwe uthango athintwa ukuthi abe ngaphezulu ukuze kunxeshezelwe ukugqunywa okumelana nokubola kumabhawodi.
