Prepainted galvanized steels with brand names of Molawan, ColoRite Standard, ColoRite Premium, and ColoRite FluoroCarbon are manufactured to meet the technical requirements of various industrial applications of prepainted galvanized steel, in terms of flexibility, stain resistance, corrosion resistance, surface hardness, and scratch resistance.

UNICOIL Prepainted Steel Brands

Our prepainted galvanized products are available in six standard colors (refer to the UNICOIL color chart). Other colors can be chosen from the "Classic RAL Picker," or you can send in a sample chip to UNICOIL for color matching. UNICOIL has a vast experience in color matching.

UNICOIL uses custom-formulated primers consisting of corrosion inhibitors and pretreatment to produce products with enhanced corrosion resistance. A full system of chrome-free products complying with RoHS (Restriction of Hazardous Substances) requirements are also available.

Customers with other Special requirements should contact a UNICOIL sales engineer or use the product recommendation form on our website.

UNICOIL uses only lead-free paints for all its products.

Product Packaging

 

Standard Packaging for Prepainted Steel Coils

Special Features of Prepainted Galvanized Steel Packaging

• Edges protected with cardboard edge protectors
• UV-resistant tubular plastic wrapping
• Stretch-film tight wrapping
• Steel outer ring
  • Vertical packing ("eye to the sky")
• Sturdy wooden pallets
• Product label with all relevant information

Seaworthy Packaging for Prepainted Steel Coils

Additional Special Features of Seaworthy Packaging

• Additional cardboard wrapping
• Outer steel sheet jacket
• Fumigated and bolted wooden pallets

Premium Packaging for Slitted Coils

Prepainted steel slitted coils are packed vertically ("eye to the sky," on pallets). Each slitted coil is separated by wooden spacers for ease of handling, and each such separated set of slitted coils is enveloped by a VCI (vapor-corrosion-inhibitor) paper and placed on a strong wooden pallet. A steel outer ring is put around the set of slitted coils, and the entire set of slitted coils is tightly strapped to strong wooden pallets to ensure protection from damage during handling and storage.
