Light Grey Sentri™ XP The latest SFS
achievement in superior coating technology, light grey is less noticeable
on the underside of raw galvanized steel and painted white decking. This
is a valuable cost savings for applications where the underside of the
deck will be exposed, such as in “big box” type retail stores and modern
warehouses. Light Grey Sentri XP, used on all #12 fasteners, eliminates
the need for white fasteners in these applications. There is not a lighter
e-coating used in the flat roof market today that compares with Sentri XP
light grey for combined corrosion resistance and aesthetic appearance.
