    High Quality Dx51d Z30-275g Cold Rolled Galvanized Steel Coils for Roofing Sheet

    Is cold rolled steel stronger than galvanized steel?
    Cold-rolled steel has superior directional strength, which is valuable for certain high-load applications.


    What is the difference between GI and hot-dip galvanized?
    The key difference between galvanized and hot dip galvanized is that most galvanized materials have a smooth

    and sharp finishing, whereas hot sip galvanized structures have a rough finishing. Galvanization is a process

    of preventing metal surfaces from corrosion.


    Which is better galvanized or hot dipped galvanized?

    As mentioned, pre-galvanized components are usually only immersed in the galvanizing bath for a very short time, resulting in a relatively thin coating. The thicker zinc coating produced by hot dip galvanization offers improved rust and corrosion protection versus pre-galvanization.
