Steel with zinc-magnesium alloy coating

Maximum protection for the steel against corrosion in highly aggressive environments. The zinc-magnesium metal coating gives the steel exceptional surface protection, with corrosion resistance greater than that of other metal coatings. The automatic repair of the cut edges, where corrosion usually starts, makes this coating an optimal, unprecedented solution, providing a more uniform, lighter coating for structures and a longer useful life. Designed for all kinds of exterior work, especially when exposed to corrosion, whether environmental, saline, in alkaline environments, with chloride, ammonia, or due to extreme weather.

Pre-lacquered steel

Pre-lacquered steel is comprised of various layers that give the steel its aesthetic and functional characteristics. These layers are as follows: base metal, metal coating, pretreatment, primer and final coating, on both the upper and lower sides.
