Cold Rolled GI/GL/PPGI/PPGL Galvanized Steel Coil

Cold Rolled GI/GL/PPGI/PPGL Galvanized Steel Coil
Galvanized Steel Coils is specially designed steel sheets that are employed in several furbishing and manufacturing purposes.
Steel coils are thin sheets that can be rolled up into incessant coils. The galvanized coil is employed outdoor, as it shows anti rusting tendencies. Most significantly, it is used in constructing strong roofing system.
