Product Description
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.
