Prep-galvanized(or mill galvanized) steel is produced by unwinding steel coil and passing it continuously through a bath of molten zinc and then past air jets to remove excess zinc from the surface.The process is closely controlled to produce a thin, even and ripple free zinc coating with very few imperfections. Because this pre-galvanized steel coil must then be cut to shape during subsequent manufacture of support equipment, the edges of the finished components will have no zinc coating. This aspect, together with the relatively light zinc coating provided by the process, make pre-galvanized service supports suitable for indoor, low-corrosive environments(particularly where an aesthetically attractive appearance is important) but unsuitable for humid indoor or outdoor applications. XK strut channel use all the good quality pre-galvanized steel coil as Q195 , all the coil and plate we will check the galvanized thickness to meet clients different order.
