Guy Hlau ASTM A475
Galvanized Hlau yog tsim rau ASTM B498; ASTM A 475; BS 183 thiab lwm yam. Cov hlau zinc coatings siv los ntawm cov txheej txheem galvanizing yog ib txoj hauv kev zoo los tiv thaiv corrosion hauv hlau. Galvanized hlau rau daim ntawv thov cable muaj nyob rau hauv Chav Kawm A txheej; Class B txheej thiab Class C txheej.Class A txheej yog smoother, tab sis tsawg corrosion resistant dua hnyav galvanized coatings thiab feem ntau yog siv nyob rau hauv ib txwm hlau ua hauj lwm daim ntaub ntawv. Qee cov neeg siv kawg suav nrog lub tawb, lub thoob tuav, lub tsho hangers thiab pob tawb.Class B thiab Class C txheej yog siv nyob rau hauv tej yam kev mob uas atmospheric corrosion yog heev. Cov neeg siv kawg suav nrog cov kab kev txhawb nqa qoob loo uas siv tshuaj lom neeg, pas dej ua ke los yog cov saw mesh hauv thaj chaw ntug dej hiav txwv.

Tensile zog (Mpa)
Lub zog tensile yog txhais raws li lub siab tshaj plaws load tiav nyob rau hauv lub tensile xeem, muab faib los ntawm tus ntoo khaub lig-sectional cheeb tsam ntawm cov hlau xeem daim. Galvanized Hlau yog tsim los ntawm cov xov hlau mos, nruab nrab thiab tawv qib. Cov lus hauv qab no qhia txog qhov tensile ntau yam raws li qib:
