Kukhazikika kwa ASTM A285 kwa mbale zokakamiza, chitsulo cha kaboni, mphamvu zotsika komanso zapakatikati

makulidwe: 6mm mpaka 300MM,
m'lifupi: 1500mm kuti 4050mm,
Utali: 3000mm kuti 15000mm

Zolemba Zotsatiridwa:

ASTM Sandards:

A20/A20M: Zofunikira zonse za mbale zachitsulo zotengera zokakamiza.

Zofunikira Zonse ndi Zambiri Zoyitanitsa:

Kuyesa ndi kuyesanso njira, njira, kulolerana kwa kukula, misa, khalidwe ndi kukonza zolakwika, kuyika chizindikiro, kutsitsa ndi kuyitanitsa zidziwitso ziyenera kutsatira A20/A20M.
Kuphatikiza pazofunikira, zofunikira zina zowonjezera zilipo.
Ma coils amachotsedwa ku A285 mpaka atadulidwa kukhala mbale.
