Cov tshuaj muaj pes tsawg leeg ntawm cov hlau txiav txim siab nws cov khoom siv tshuaj thiab, rau qee qhov, nws lub hom phiaj. Yog li, rau cov khoom txias sib sau ua ke siv cov pa roj carbon tsawg uas muaj txog li 0.08% C. Cov ntsiab lus tsis tshua muaj cov pa roj carbon monoxide ua rau kev sib sib zog nqus ntawm cov hlau.
Nrog rau cov kev xav tau rau cov khoom siv ntawm cov khoom siv txias txias, ntau qhov yuav tsum tau txiav txim siab nws txoj kev tsim nyog tau tsim. Lub microstructure ntawm cov ntawv hlau txiav txim siab ductility, ceteris paribus, decapitated sheet hlau yog tsim nrog ib tug tuab ntawm 0.25-2.0 hli thiab muab nyob rau hauv daim ntawv ntawm 510 × 710, 600 × 2000, 710 × 1420, 710 × 2000, 750 × 1500, 1000 × 2000 thiab 1250 × 2500 mm, raws li txoj cai nyob rau hauv lub annealed mob. Sheet hlau nrog lub thickness ntawm 0.25-2.0 hli kuj muab galvanized.

Nrog rau qhov txias dov ib daim ntawv ua los ntawm alloyed, structural steel, structural alloyed ntxiv-zoo steel rau tshwj xeeb lub hom phiaj, corrosion-resistant thiab kub-resistant, tsawg-carbon hluav taws xob, siliceous hluav taws xob steels, tin, yog tsim; nrog rau cov kab xev txias (piv txwv li, grain-oriented), hluav taws xob rau cov hlau nplaum, cov cuab yeej, caij nplooj ntoos hlav thiab lwm yam.
