RAL Color ASTM Standard Prepainted Galvnized Steel coil For roofing
and sandwich steel panel sheet
Prepainted galvanized steel coil is to paint on the galvanized
steel base materials in order to prevent the materials from rust,
which is more reliable than hot dip galvanized steel coils.
Prepainted galvanized steel coil is produced by the process of
painting organic coating on the both sides of galvanized steel
surfaces, usually with primer plus paint on top and back with
primer according to customer’s different requirements. It has good
characteristics of corrosion resistance, proper decoration etc.
Usually prepainted galvanized steel coils are used in production of
roofing sheets, sandwich panels, decoration panels and many other

1. Excellent corrosion resistance: The zinc layer provides a good
protection of Pre-painted Galvanizeed Steel Sheet.
2. High heat resistance: The reflective surface of the material
aids in efficiently reflecting the sunlight away and in turn
reducing the amount of heat transmitted. The thermal reflectivity
converts into energy savings.
3. Aesthetics: Prepainted Galvanized steel sheet is available in
plethora of patterns and multiple size-s as the requirements that
given by our customers.
4. Versatility: can be used in the various areas.
