Dibadda Galvanized Steel Coil leh Konteenera | Duruursan & Korosiya Kacaysan

Dhulka steel galvanized loo sameyn karaa dhammaan standard kuwa ugu yeero leh ee ka mid ah formability, corrosion resistance, iyo impact toughness. Dhaqanka waxaa la jirin sharcii qasaar—exposure to saltwater marka uga soo saarayo, temperature fluctuations, iyo mechanical stresses—sidoo kale waxaa u dhacay zinc coatings Z275 ama lacagta (kasta oo ah Z350) marka hore ee carruurta. Dhulka ka mid ah ayaa lagu baahnaa yield strength dheer (kan tan ayaan <300 MPa) si deep drawing lahayd corner posts iyo corrugated side panels sidoo kale ma ahan cracking. ASTM A653 Grade 80 waa maxayd ah, ku jira minimum tensile strength 550 MPa iyo elongation >18% si ay ugu yimid ductility. Qeybka fabrication ayaa lagu sameyn karaa roll forming for side walls, spot welding for panel connections, iyo edge deburring si aan coating damage. Corrosion protection waxaa lagu hubi karaa paint systems addition over galvanized layer, xusuus sidoo kale food grade containers. Container manufacturers waxaa lagu sameyn karaa flatness tolerances (<3mm/m) si aan proper stacking iyo sealing. Trendyada reerku waxaa lagu sameyn karaa galvalume (Zn Al) coatings si aan heat reflectivity carruur ah refrigerated containers iyo lightweight high strength steels si aan increase payload capacity sidoo kale ma ahan durability.
