Aluzinc & Galvalume Steel Chev
Lub galvalume & aluzinc steel ntawv hauv coil siv cov ntawv txias-kuav los tiag steel ntawv ua substrate thiab solidified los ntawm 55% txhuas, 43.4% zinc thiab 1.6% silicon ntawm 600 degree. Nws ua ke nrog kev tiv thaiv lub cev thiab kev ua haujlwm siab ntawm txhuas thiab electrochemical tiv thaiv zinc. Nws tseem hu ua aluzinc steel kauj.

Qhov zoo:
Muaj zog corrosion kuj, 3 npaug ntawm galvanized steel kauj.
Qhov ntom ntawm 55% aluminium yog me dua qhov ntom ntawm zinc. Thaum lub luj yog tib yam thiab lub thickness ntawm lub plating txheej yog tib yam, thaj tsam ntawm cov galvalume steel ntawv yog 3% los yog loj tshaj li ntawm cov galvanized steel ntawv.
1) Qhov twg lub zog tawm los yog txhais, qhov tseem ceeb siv rau lub zog siab zog ReH.
2) Rau txhua hom hlau, tshwj tsis yog S550GD, qhov ntev ntawm 140 MPa tuaj yeem xav tau rau lub zog tensile.
3) Raws li cov khoom thickness, qhov tsawg kawg nkaus qhov tseem ceeb ntawm elongation ntawm pob txha raug txo raws li hauv qab no: 0.50 mm < t < 0.70 mm ( minus 2 units), 0.35 mm < t < 0.50 mm ( rho tawm 4 units ), thiab t < 0.35 mm ( rho tawm 7 units ).
