Galvanized Carbon Steel Coil: Ku yaal & Versatile ee Dhibaato

Dhulka carruurta carruurtayga waxaa la jiray mid ka qarsoomay carruurta carruurla iyo ugu dhexeeya carruurta carruurla ah ee ku jira zinc coating, si aad ugu yahay karaama ah oo dhan leh koonfurta carruurta carruurla ah ee dhexdeeda iyo carruurta carruurla ah ee dhexdooda. Dhulka wuxuu ku jirin hot dip galvanized, immerses in molten zinc si aad ugu yahay dhacdo dheer iyo zinc iron alloy layer (60 275g/m²) ee ku jiraan protection carruurta carruurla ah ee sacrificial—waxaan idinka soo jeedaa zinc carruurta carruurla ah ee dhexdooda, si aad ugu yahay degdeg ah haddii coating ay ku sameeyeen. Cold rolled ama hot rolled carbon steel wuxuu yeelay substrate, marka ay low carbon grades (carbon ≤0.20%) ku jirin carruurta carruurla ah ee dhexdooda. Process carruurta carruurla ah waxaa lagu baabbiyay paintability, si aad ugu yahay coatings kale (polyester, fluorocarbon) leh aesthetic appeal iyo protection kale. Xaqiiqda carruurta carruurla ah (400 550 MPa) iyo yield strength (235 355 MPa) waa mid ka heli karaama ah, marka aan zinc coating ay ku sameeyen weight kale. Galvanized coils waxaa la jiray in lagu ammaansaday construction (roofing, wall cladding), automotive (chassis components, underbody parts), iyo infrastructure (highway guardrails, signage), sababtoo ah ee coastal areas ama industrial zones ee ku jira high humidity/pollution. Salt spray tests (up to 1,000+ hours) waxaa lagu baabbiyay corrosion resistance, markaas bend tests waxaa lagu baabbiyay coating adhesion during forming. Haddii environmental regulations ay ku sameeyen, waxaan idinka soo jeedo manufacturers eco friendly galvanizing processes (low zinc consumption, water based post treatment) si aad ugu yahay sustainability goals.
